Arbitrary Headcount Limit

"No no no, you don't understand. You see, I only had one ring left to protect my teammates from being in the Edge, so I had to leave the rest behind. I mean, what kind of idiot goes into battle with half his team behind? How stupid would you have to-... R-Rolf, why are you beating your head against the wall like that?"

Trope common in Real-Time Strategy games, in which the overall number of units or the count of a particular powerful, but not unique unit are limited by assigning a completely arbitrary Cap to them. This limit is often far lower than what the resources available or the technical limits of the game engine could allow. Particularly ridiculous when the rule can be broken through scenario design or using a perfectly legitimate game feature. Most often implemented as a way to enforce game balance.

It may be hardware related. Doing rendering, AI, collision, etc. for many units at once can slow a game down, particularly on high graphics settings, resulting in a need to limit how many units the player may have at any given time. Since developers have to take console hardware limitations into account, or multiple PC configurations, they will usually try to balance between gameplay, and allowing the game to still run smoothly.

Many Role Playing Games have this as well, centered around the three-to-six-person size of the active party—see Player Character Calculus for additional classification. In addition to the Hand Wave explanations common in Real-Time Strategy games, Role Playing Games can use the plot to explain the size limit. For example, in Final Fantasy IV, every time it looks like the party will grow beyond five, one of your current members will discover pressing business elsewhere. Or die. Or betray you.

  • Maniac Mansion is perhaps the only example in this genre. Dave has six friends who he can ask to help him rescue Sandy. He can only bring two no matter how motivated the other four seem.

    Fighting Games 
  • Until the Dreamcast came out, most console wrestling games only ever allowed 4 wrestlers in the ring at the same time, regardless of the match type. This included Royal Rumble matches, where you would fight through 29 other wrestlers but only 3 at a time.

    Platform Games 
  • The enemies in Yoshi's Island are subject to a headcount limit when spawned by pipes or other similar sources. Oddly, the limit depends on Yoshi - specifically, the number of eggs he has. If the pipe/whatever plus the number of eggs Yoshi has number six or more, it will stop spawning monsters. The real reason, of course, is because these spawn points really only exist to help Yoshi fill up on ammo.
  • The Lost Vikings 2 has five playable characters. However, only 3 are present per level. It is lampshaded throughout the game.

    RPG — Eastern 
  • Hand Waved in Chrono Trigger: When you gain a fourth party member (the maximum number of people allowed in your party are three), one of them has to stay behind to hold open a door, later on, when you're all together and travel through a time gate you end up at the End of Time. There you learn that no more than three people can travel to an era without getting redirected, so the remaining party members have to stay while the others are adventuring (Why can't they go through in two groups? Quiet, you.). However, you can switch them at will, and anytime you go to the End of Time, you can find them standing there.
    • Leads to a bit of Fridge Logic, taking more than 3 people sends you to the end of time, but the end of time has time portals to everywhere, so they would want every time portal trip they take to go there.
    • This is especially bad in Chrono Cross. There are forty-five recruitable characters, but only three people allowed on a team - and one of them has to be Serge (until New Game+). This simply does not leave much room for experimentation.
  • The Final Fantasy series is a repeated offender:
    Stone Dragon: BLARG! I'M A DRAGON! OR TWELVE!
    Red Mage: Impossible! Only a maximum of nine enemies may be onscreen!
    Stone Dragon: FUCK YOU.
    Red Mage: Run.
    • Final Fantasy IV as stated above is a prime example of RPGs that explain the party size limit with plot. However, the GBA remake brings just about anyone back to the party before the final dungeon (and the added bonus content), allowing the player to pick his favorites like in most of the later games. There is no real explaination as to why they can't just all go and bash the Big Bad in the head with superior numbers, though...
      • It does, however, have the most party members available in battle of the main series, with five. The other games have four, or only three.
      • Final Fantasy IV: The After Years takes this one step further in chapter 10 (or the first part of the final chapter on the Wii): Assuming you played all the previous chapters and kept all characters susceptible to a Final Death alive, you will start the chapter with ten characters. As you complete mandatory quests, six more will join you on your airship (again, assuming you played all the previous chapters). However, the game will not let you swap characters (yet) at all: your team is Rydia, Edge, Luca, and the Man in Black, which isn't even a full five characters, with no explanation given as to why you can't at least pick someone on your airship to fill that empty fifth spot. Later on, you get to pick your team of five (out of twenty-two), which is more standard.
    • In Final Fantasy VI, when the party is attempting to land on the Floating Continent from the airship, you are puzzlingly told that you can only take three people along, even though the party limit is four. You find out later that Shadow is down there waiting for you, and his presence is required at the end of the Floating Continent sequence, but still. At the time you can't help wondering what part of this whole plan would be messed up if one extra person went with you.
      • Before that, on the haunted train, you may recruit ghosts to have up to four party members, but if you try for a fifth member, Sabin objects that too many members would slow you down. Frankly, in an area that dangerous, I'd take slow over weak.
      • Later on in The Very Definitely Final Dungeon, though you still have the same party limit, you need to form three parties in order to reach the Big Bad. The 3 parties merge upon reaching the Big Bad into a party of 12, while you still fight in groups of four, once the ones in battle are all KO'd, they would be switched with the next in the line up.
    • In Final Fantasy VII, near the beginning of the game when the number of allies travelling with the main character exceeds the 'recommended' amount, they split into two groups and arrange to meet up at the next plot-relevant location because, technically, they are all wanted terrorists. It is essentially decided that, since the antagonists are searching for a group of 5 people, they wouldn't stop to question a group of 3 and a group of 2 moving separately.
      • Normally, the player controls one group of 3 characters during a battle, but when fighting the Big Bad the player is allowed to equip ALL 8 characters and may cycle between them at any point in the battle, if it seems like one group is struggling to make progress alone. Not unique, but certainly unusual among RPGs to allow the entire cast to take part in a fight.
      • Then, you have the Fort Condor proto-RTS sequences. The gist of these, according to the inhabitants of the fort, is that they have to hire mercenaries in order to repel attacks by the Shinra. Naturally, they ask you for your monetary contribution. Eventually, you are forced to take an active role as commander, and this involves buying the services of various units and placing them around the battlefield. Arbitrary Headcount Limit rears its ugly head here, because you are limited to placing a maximum of twenty. By the time you reach this sequence, it is entirely possible that you have enough money to fill every square foot of the battlefield with units.
    • Final Fantasy IX deals with this trope in several different ways. At the very beginning, you only have three or four characters in the party at a time, with the guest character getting a bridge dropped on him to make room for the fourth. Later on, when the fifth main character appears, the party splits up into two groups, each of which can accommodate the limit. When the two parties reunite, some of the characters are Put on a Bus for the rest of the disk to make room for the final party members. When the entire party unites at the start of Disk 3, they are frequently seen gathering in various dungeons, sometimes offering explanations as to why they split up again, but by the final few dungeons it's assumed that the entire party is travelling together, and the fact that whichever four characters the player isn't using don't seem to be doing anything is pretty much Hand Waved.
    • Final Fantasy X and Final Fantasy XII limit you to three characters at a time. X uses a Lazy Backup tag system where you can swap characters mid-battle, but if all three active characters get KO'd, you're screwed. XII allows unconscious characters to tag out at any time.
      • Final Fantasy XII: Revenant Wings however makes the arbitrary headcount 5 but that is because it is a real time strategy game. One does wonder however why the other 4 characters are not allowed in battle when your army size can be maximized to theoretically 45 members.
    • In Final Fantasy: All The Bravest, you start with an astounding 12 party slots, and as you level up or post to Facebook or Twitter through the game, you gain more party slots, until you end up with a grand total of 30 party members. All of your party members fight with you at once. (Shame they all die in one hit...)
  • In Phantasy Star IV, until the end of the game there are only five characters in your group at any given time, and when everyone finally gets together to fight the Big Bad, there are only five artifacts of power that'll let their wearers go into the lair. Of course, this is somewhat moot, as the fifth of those artifacts (the Rykros ring) was not actually equippable by any of the characters; no matter who you picked, your fifth party member didn't get one anyway.
    • The Quote at the top of the page referenced Phantasy Star 2 which did have an arbitrary limit on party size. Phantasy Star and Phantasy Star 3 both get around this by having the size reflect the maximum characters available at any given point. Phantasy Star 2 however just randomly limits the size of the party.
      • Rolf's solo adventure spinoff states he dislikes working with others and would rather have a small team if he HAS to bring one along, since small teams mean less chances for others to mess up. Since he is basically team leader, that is very likely the reason why he only brings a handful of people along. Apparently he's also totally cool with letting a bunch of complete strangers crash at his house for weeks at a time.
  • The entirety of the Tales Series has four as this number, with the actual party size ranging from six (Phantasia) to nine (Destiny). What, if anything, the extra members are doing while the others are fighting is never explained, barring a fight in Abyss where the two extra members have to secure an escape route.
    • Tempest, Innocence and Hearts have a limit of three. The GBA Narikiri Dungeon games also had four parties of three each, but since the actual party size was every character in the first five games...
    • Hearts also averts it, like Mugen no Frontier above, by introducing the "Link Attack" system, by which characters in the back party can be summoned in to use attacks or spells. Since characters Linked in can't be damaged or interrupted, it's useful for calling out a Raise Dead or Last Disc Magic with a charge time of "eternity".
    • If you go a long time without switching party members in Tales of Vesperia, you may get a skit where the inactive members complain about being left out of the action. Yes, the others really are just sitting on the sidelines.
    • In Tales of Xillia, you can only have four party members onscreen during a battle... but you can swap an inactive party member with an active one mid-battle.
    • Tales of Xillia 2 plays this straight again, only allowing four party members when you are out and about. The plot forces circumstances, so that only four members (three, since Ludger must always be in the party during the main arc) are in a location.
    • Tales of the Abyss does give some justification: the only thing preventing your allies' fonic artes from doing just as much damage to you as to the monsters are marks laid on the team by your spellcasters, and they can't mark too many people at once. Essentially, up to two of your party members are getting left out because they can't be made Friendly Fire Proof.
  • In Golden Sun The Lost Age, you eventually acquire a party twice as large as the cap of 4 in battle, the result is the ability to switch a single character from the team in battle with one in the 'on hold' team per turn, and should all 4 of your party get knocked out they would instantly be swapped with the back team. note 
  • Riviera: The Promised Land states that going into battle with more than 3 members would make things too crowded, but this does not explain why battling party members can't tag out.
  • In Brave Story: New Traveler, you can not control more than three people in the party, one of them being your character.
  • The Last Remnant has an extremely generous limit that increases over time.
  • In Skies of Arcadia, the four-person party is mostly explained by the plot — the main trio are bestest friends and stick together, while the fourth slot is occupied by whoever's present for the plot at the time. The game really runs into an Arbitrary Headcount Limit towards the end, however — you can pick who to take with you into The Very Definitely Final Dungeon, but taking more than one of the fourth-slot characters is forbidden. The crew of your Cool Airship is also limited. You can recruit 2 crewmembers for each position but only one can be on duty, even if the job is in no way exclusive like "sailor" or "merchant".
  • Parodied in Dragon Quest IV. At the beginning of chapter five when the hero first enters Branca, a four-person team is leaving the town. If you talk to them, one will tell you that their party is full and that you'll need to find another one to join.
    • By the time you have more than four characters in your party in chapter five, you'll have the wagon, which the inactive party members ride inside of. When you enter places that the wagon won't fit (like most caves and dungeons), the reserve characters stay with the wagon to keep your party size at four. Presumably, they're watching over your stuff and making sure monsters don't eat the horse or something. When the wagon is present, you can swap out party members at any time in battle, and if your whole active party gets wiped out, the reserves will leap out to continue the fight.
    • Dragon Quest V oddly reduces the active party size to three (with an additional five in the wagon), despite the game's introduction of Mons meaning that you could end up with dozens of potential party members to choose from. The DS remake brings it back up to four active members... but also greatly expands the number of monsters you can recruit. Given that the wagon will be with you when you fight the final boss, there's no logical reason why shouldn't just dogpile him, but naturally the game won't let you.
    • Dragon Quest VII, is absolutely horrible about this, sticking to the series' usual four-person party... when there's only about six main characters anyways. Leading to more than a few Contrived Coincidences to keep the "extra heroes" busy until it's time to rotate them into the plot again. Made worse when one dungeon guest characters count toward this maximum party size.
    • Averted in Dragon Quest VIII since there are only four playable characters.
  • Last Scenario only lets you use 4 of your 7 characters. This is made even weirder because the cutscenes make it clear that the whole party is traveling with you.
    • The spiritual sequel Exit Fate had a party limit of eight out of... seventy-five. Also, two of those eight occupy the entourage, and cannot fight, but any of the other six may spend an action to trade places with them. Exactly why two people who are officially employed soldiers decide to cheer from the sidelines instead of aiding their teammates is not clearly explained.
  • The main Pokémon games only allow you six Pokemon at a time, while the rest are kept to the PC; it's explained in the Pokémon Special manga as a recommendation by the Pokemon League due to the fact it would be difficult for a single trainer to care for more Pokemon than that at a time.
    • Various spinoffs have other limits. Pokémon Ranger gives you a limit of seven. Pokémon Mystery Dungeon gives you a limit of four as well as an overall size limit; it can't exceed six stars, even if it's just two Pokemon. Pokémon Conquest has six Warriors to a kingdom, and each Warrior has their own limit of how many Pokemon partners they can have, from one to eight.
  • In Star Ocean, four are required (meaning you only get to pick the other four, compared to six in the second game) and only one can be booted. The Enhanced Remake also gives you the chance to not exactly boot one character, but get a better one instead who is hidden. In addition, one is fairly difficult to find without an FAQ, while another will only become available fairly late in... at which point you've probably already filled up all seats.
  • In Star Ocean: The Second Story, you can have up to a party of eight characters, but only four appear in combat. The rest never show up unless you transfer them into the active party, even though they're present whenever the player initiates a Private Action (and the eight-person group is seen splitting up to do their own thing at a town's entrance).
    • The player usually gets a choice of 6-7 characters on average (on top of the two mandatory ones), but you can also miss or fail to recruit certain hidden or optional characters. Notably, Chisato will refuse to join Claude/Rena's party if it's filled with the maximum eight party members, even though she's been trailing the characters throughout the gameworld and wants to help them. There's no explanation of why she can't join anyway as a support helper.
  • In the Director's Cut of Star Ocean: Till the End of Time, 2 mandatory characters were added, preventing you from recruiting all of the original 8 party members. One of three of your previous companions joins you, depending on if you've completed Roger or Albel's sidequests or not. If you want one of the other two as well, then you have refuse Peppita's offer to rejoin you on the Moonbase.
  • Valkyrie Profile always has quite a bit of playable characters but only three manifest at once. This is explained with how the Valkyrie only manifests the einherjar that she wishes to train. Except that Valkyrie Profile: Covenant of the Plume doesn't actually have a Valkyrie as the main character...
  • Explained in The Reconstruction by Wadassian law restricting your guild to six armed combatants at a time. But then Wadassia is reduced to ruins, and you're still using six characters to fight the final boss and save the world.
  • Infinite Undiscovery allows 4 characters, or 3 if one of them is Gustav. Out of 18. And some of them are arbitrarily forbidden from being in the same group as the Player Character, restricting their use to Let's Split Up, Gang-situations — without much explanation beyond the few that won't join your party because they hate you.
  • Lost Odyssey has a limit of 5. Even though the formation interface has 10 positions, you're only allowed to fill half of them.
    • The crazy thing is, you don't even have that many people. You could theoretically stuff every character on the field and still have a slot empty.
  • Played agonizingly straight in the Suikoden series. You have an entire army (including several dozen character available for use in your party), but you can only take six at a time. Suikoden III added a seventh slot for 'support' characters.
    • In Suikoden IV, this was downsized to a four-person party, plus a 'support' NPC. After this proved unpopular with players, Suikoden V responded by upping the limit to ten — while you could only have up to six actively fighting in your party at any given time, there were four extra slots you could use to bring along other characters, be they supporting NPCs or other fighters. This helped with Leaked Experience and provided an alternative whenever you had to bring certain characters along for plot-related purposes.
      • There's a bit of missable dialogue with your strategist that actually explains this: when going on land, you have to be careful not to attract undue attention, so a small party is better unless you want the whole Kooluk army (which vastly outnumbers you, to say the least) on your tail. As for the ship, you are restricted to 3 parties (12 people total), but they are freely switchable in battle, and that's because there's not enough space for more to fight on the ship, since the rest of the space is taken up by the currently-attacking monsters and overcrowding the ship's bridge can result in someone getting shoved overboard in the confusion.
      • A major part of what made the reduced party size in Suikoden IV unpopular is that it makes many of the series' signature Unite Attacks less convenient to use...especially the one that has four participants. Since The Hero isn't one of those four, the attack is only available in shipboard combat.
  • The Etrian Odyssey series allows you to have a decently sized Guild, but you can only have up to five members in your adventuring party at any given time. Word of God admitted that this was meant to make players feel their parties were always "incomplete" somehow; six-member parties were simply too well-balanced for a game striving to be Nintendo Hard.
    • In the fourth game, in each of the major dungeons you can encounter an NPC who will increase your party to six (there are six slots to place five characters, the NPC will take up the sixth slot). However, the NPC will only join for that dungeon, and not even every floor of that dungeon. And once you beat the boss of that dungeon, the character joins your party permanently, and you're back to only five characters.
  • In Endless Frontier, your entire party can participate in battle, but only four are active and fit on the screen. The non-active characters can use support attacks during the fight, up to certain limits, with some characters only capable of participating through support attacks. The sequel shows off how arbitrary the limitation really is, with a lot more support-only characters, one character who has a partner, and still the same four-character headcount limit.
  • Breath of Fire II only allows four characters in the main party at once (out of a possible nine, one of which is technically optional), while the rest remain in Player Headquarters. III does the same, allowing only a party of three out of six. The rest of the games, however, avert both this trope and Lazy Backup by allowing party members to switch during combat, or in the case of Breath of Fire: Dragon Quarter by only having three characters in the first place.
  • Kingdom Hearts only allows you to use three characters at a time... which seems more than a little pointless, given you never have access to more than four at a time anyway, and given that all experience is leaked.
    • In Kingdom Hearts 3D, you can have a maximum of 99 dream eater allies, but are only allowed to have two active ones and one reserve at any given time.
  • Shin Megami Tensei games typically have a limit of 4-6 party members, including the protagonist. This is explained by the device you're using to summon your allies being only able to keep so many demons manifested at a time.
    • In Persona, there were eight possible party members aside from the protagonist. Depending on which quest you were on, one to three of those slots was locked in. The remaining slots could be filled at key points in the story, but once your party was full, additional party members were immediately sent to safety. The Persona 2 Duology also had a cap of five, but (with a single exception in Eternal Punishment, based on which reality-warping rumour you decide to spread) you don't get to select which party members will fill those slots. However, eventually the character you pick will leave the party for the "true" fifth party member, and it's not really explained why you can't have all six.
    • Persona 3 justifies this by having the party be an exploration team. That way, if the entire team bites it, SEES won't be wiped out. (...Well, the world will end if the protagonist is killed, so they won't really get a chance to use the backup. But it's a nice thought.)
      • During the Final Battle, when all of SEES is present at the Boss Arena, the limit is enforced when Fuuka detects a large number of Shadows climbing up towards them. Mitsuru commands the rest of the party to Hold the Line against these Shadows and defend the main group while these fight the final enemy.
    • Persona 4 looks like it has a similar set up as the previous game... but then the entire party inexplicably shows up in the final room of each dungeon. There is, admittedly, a portal leading there from the lobby.
      • It's at least partially explained when you revisit a dungeon. Occasionally, members of your party that aren't actually with you can randomly appear in an empty room of the dungeon. It's implied that they've formed an independent B-team and fight Shadows in other parts of the dungeon. Of course, you never see the products of this endeavor.
    • In Devil Survivor, you can never have more than four humans on the field (counting the main character).
  • Sweet Home has a limit of three members per party, drawing from a pool of five. If you try to have a fourth join, the other character will say that it would be best if the fourth character stays separate. If a character rescues the fourth from a pit, one of the original three will be disconnected from the party. The ability to form multiple parties that could be switched between at any time, in addition to being able to combine parties during combat, lessened the impact of this, however.
  • Secret of Mana and Seiken Densetsu 3 have this for the enemies, only allowing up to three on screen at once. NPCs also count against that, so there's one mountain trail where Neko will sometimes appear, but only if there are two or fewer monsters currently active.
  • Inazuma Eleven has an amazing number of 100 members allowed on the team at any one time, but given its Cast of Snowflakes, arguably even that number isn't enough. As for the matches themselves, since it's soccer, 11 members are on-field while optionally 5 are on bench.
  • Wild AR Ms 5 only allows you to have 3 characters in battle out of the 6 playable characters. This is down from 4 in the previous game.
  • Inn Shining the Holy Ark, only four characters can appear at a single time in battle. However you could freely switch characters over, so if a character is killed you could replace them provided you had another character to take their place.
  • Played straight in Grinsia as the group reasons that having more than four active party members would be too conspicuous and they'd get in each other's way during battle.
  • Conception II: Children of the Seven Stars limits each dungeon dive to Wake, paired with a heroine, and three teams of three Star Children. While eleven seems like a lot, that's out of seven heroines and up to ninety Star Children. It's implied 10 is the maximum number of people that can accompany Wake without over-taxing his ability to provide them with ether energy.
  • Monster Hunter allows only two large monsters on the map at any one time. This is a good thing, especially when fighting Qurupeco, because otherwise it could just summon large monsters ad infinitum and fill the map with Rathians, Deviljhos, and the like.
  • Lufia: The Legend Returns has a max-party size of nine out of thirteen members. One aspect of the game's battle system is that only one member of each of the three columns can attack per turn. This averted with Mousse and the Egg Dragon, who attack automatically every turn without taking up that column's allotted member, or confused characters.
  • In Lufia: The Ruins of Lore, you can have up to eight party members—the three main characters, two other human(oid) characters, and the three heroes' Mons. You can only have four in battle at a time, and only two can be monsters. (This may be because We Cannot Go On Without Humans.)
  • Sands of Destruction limits you to only three people in battle at once; the rest are Lazy Backup. The entire party shows up in cutscenes, and you can switch characters any time outside battle, so you know they're all there; there's no explanation as to why only three fight at once. Those who watch instead of participate in fights only get 1/3 to 1/2 the Experience Points of the active party, and get no Customization Points.
  • During the strategy game-esque Liberation Missions in Mega Man Battle Network 5, the player isn't given a choice in which characters to use in a specific mission (unless it's in the DS' Updated Re-release, where characters are interchangeable with their version counterparts), but the number of characters can only go up to five out of seven heroes. Like Chrono Trigger, some Liberations give an excuse for why the other two characters have to sit the mission out.
  • The Neptunia series traditionally limits you to four characters on the field, each with one partner they can tag out with. Out of a party of many, many more than that number; Re;Birth 3 has a whopping 26 party members in the postgame. Most damningly, cutscenes make it clear the whole crew is always traveling as a pack. Since this is Neptunia, with the universal Medium Awareness and optional fourth wall that implies, it's lampshaded at least once a game.
    • This is most damning in Hyperdimension Neptunia Re;Birth1 where the battle headcount is limited to three. This appears to be a technical limitation, and the game still lags slightly during particularly flashy attacks even with the reduced model count. Later Re;Birth games, which use a better-optimized version of the engine, are back up to a party of four.
    • Downplayed in Megadimension Neptunia VII. The same limit is there, but the game is reluctant to give you enough characters to fill it out - by about the halfway point, yo can count the number of battles where you've had four party members on one hand, let alone anyone to put in reserves. Played straight when those barriers fall, though less ridiculous then in R;B3; at most, you'll have 16 characters, but that's still enough for two full teams.
  • Lunarosse is notable in that the limit is raised to five instead of the usual three or four of RPG Maker games. Still played pretty straight, though.
  • Celestian Tales Old North limits you to three people in the active party, although the total party count is six all throughout the game. An NPC at the beginning of the game explains the reasoning behind this.
  • You can only ever be training one Overlord in Trillion: God of Destruction, and they will be dispatched alone to fight the eponymous Big Bad. Discussed and justified by the fact they need to be wearing the Ring of the Tyrant to even get close to Trillion, and and it's this power they're actually training with.
  • Cthulhu Saves the World has a limit of four characters in the active party out of eight total. Beating the game unlocks the Highlander mode which exaggerates the limit to the point where there can be only one active party member.

    RPG — MMO 
  • In RuneScape, you are only allowed to have one follower, either it be a pet, summoning familiar, or someone relevant to a quest.
  • Guild Wars imposes an Arbitrary Headcount Limit in every area of the game, including outposts, where players can't even fight. In the training area it's 2; in low-level areas it's 4-6; in the high-level areas it's 8; and in elite areas it's 8-12. Usually, this limit isn't a big deal, since low-level areas are balanced for small teams. But just see what happens when a team of 4 tries to kill things in the same newbie area in hard mode...
    • Originally, players could only have 3 heroes in their party at any given time, despite having access to almost 30. These days it's possible to bring 7.
  • In Star Wars: The Old Republic, each character eventually accumulates six companions in their party. Only one companion may be active at a given time. Certain class story missions justify this by having you assign each of your companions to a specific task — while you and one companion are storming the enemy ship, for example, the others are holding the bridge, planting charges, guarding the airlock, etc.
  • Fleets in EVE Online are restricted to 256 characters with every command position filled. This can cause some issues with larger fights featuring well over a thousand players, the largest so far featuring over 3000.
  • A lot of MMORPGs have a particularly weird issue that the number of people in the party depends on what you're doing. In The Lord of the Rings Online, for example, some things can only be done by a single person, some can only be done by groups of 3 or less, some are only possible in groups of 6 or less, and some in groups of 12 or less. Especially egregious in that, depending on the classes of the players involved, there could potentially be up to twice that number of actual combatants in the party. though half will be NPCs (pets/henchmen).
  • Star Trek Online really puts the "Arbitrary" into this trope with its treatment of bridge officers. In an away team, you can bring 4 bridge officers. Except when you can't. Sometimes you can bring only 1 or 2, sometimes none at all.
  • In Video Game/Ogame, if you attempt to send a colony ship towards an unoccupied planet when you already have colonized the maximum number of planets that you cannote  you get a message that goes something as "riots on the main planet of your Empire as it's to big to be controlled forcing the colonizer to return to the planet from it was launched

    RPG — Western 
  • Fallout:
    • While most tabletop-derived CRPGs simply insist that you cough up some party members whenever you recruit more than 3-6 for no particular reason, Fallout 2 gave your character a statistical limit on their ability to schmooze people into following them, based primarily on charisma (the first game had no limit, but there were only five recruitable characters anyway).
    • Fallout 3 limits you to one follower and a dog at one time, no matter what your stats are. Various exploits allow you to break this limit, however.
      • In the Operation:Anchorage DLC, you are tasked with leading a squad to several objectives and eliminating the Commies therein. You have an amount of tokens, and different kinds of troops use different numbers of tokens depending on how strong they are. For example, a soldier with a rifle will take up 1 token, while a Mr. Gutsy will take up 5. The reason supplied is that too large a force will tip off the Commies that you're attacking.
    • Fallout: New Vegas also continues this tradition, although it is greatly alleviated by mods:
      • The number of companions is coded in-game at a maximum of one human and one non-human (ED-E or Rex) follower, with the added wrinkles of the Lucky 38 Presidential Suite being where your extra companions can stay (and complain about being stuck there while others are doing stuff). When you attempt to ask a fourth person to join your party, they'll often complain that "it looks like you're already travelling with a big enough group" and refuse to take part.
      • In addition, no companions can enter or leave DLC areas. Sometimes it's handwaved (starting Honest Hearts requires joining a caravan by yourself, as bringing others would make it unprofitable for the investors, even though it's possible to convince one of the members to back out before the DLC begins proper), but most of the time it's not (Dead Money and Old World Blues warn you that you'll be going through their areas alone before you start, and dismiss your companions without fanfare when you start them, while trying to start Lonesome Road with companions just brings up a message that "This road is one The Courier must walk alone" and makes you manually dismiss your companions).
    • The Shadowrun game for Super Nintendo similarly limited how many runners you could hire based on your charisma.
      • The Sega Genesis version limited Joshua to hiring no more than two other runners at a time, period.
  • The Lord of the Rings: The Third Age has a very strange one: Any person on the battlefield can switch out for any one not on the battlefield at any time, but only three can actually fight at one time. And if someone gets knocked out? Nobody will fill in for them. They just lie there, taking up a perfectly good slot. To make matters worse, there are occasionally guest characters who can't be switched out, even if they're very poorly suited to whatever enemy you're up against at the time.
  • BioWare is fond of this trope:
    • Baldur's Gate. Not only is your party restricted on size (6 maximum) but also on philosophical differences. If you get too popular with the rabble, the more buttkicking evil characters in the party will simply up and leave. On the other hand, the whole Dungeons & Dragons system is keyed to this, mostly because the calculation of what monsters constitute a challenge for a party depend on the said party being 4-6 strong.
    • Baldur's Gate II. Specifically coming to save a friend of yours, but not being able to lead her out of the dungeon of the Big Bad because your party was full (There actually was a dialogue option that said this). At least Bioware added an optional NPC that would betray you at a very convenient time, opening a slot for the Distressed Damsel, if you had him with you.
    • Neverwinter Nights:
      • In the original game, you could only have one henchman at any one time. Hordes of the Underdark expanded this to two, but still required you to leave three or four perfectly capable allies waiting around back at base in the first chapter.
      • In Neverwinter Nights 2, you can have as many as ten party members, but you can never have more than 3 with you at once - except for Shandra, who doesn't count towards the limit. For some reason, after Shandra dies, the limit remains at 4.
      • The second game also started out with allowing you three followers, then increased the limit over the course of the game without much explanation. In the final battle, you're controlling every single member of your group, so one wonders why no one thought to do this when fighting any of the other big bads. Meta-game-wise, it's mostly because it's very difficult for the player to keep track of so many characters.
      • Mask of the Betrayer is particularly annoying in this regard. You can take up to three companions with you, but there are only four in the first place. (To be more precise, the game has five different companions, but two are mutually exclusive and after you pick one, the other doesn't even become a companion option, so you have access to four and not five.)
    • Knights of the Old Republic:
      • In both games, you quickly acquire a party of 8 or so characters, but can only ever wander around the planet with two characters other than yourself.
      • In the second game, there is a sequence where the Exile is captured and sent to G0-T0's yacht in orbit above Nar Shaddaa. The team mounts a rescue mission (along with reformed bounty hunter Mira) to save him/her... and yet, you can only take two people total to the yacht, which is done so that the Exile will inevitably resume control of the party when s/he is rescued. There is no in-game explanation for this, despite there likely being several highly capable squadmates at this point.
    • Jade Empire is even worse given that only one other character can join you at a time. Additionally, one of these does not fight but only allows you to use the Drunken Master style. Another character is in your party pool but is only there to trade with you. With him being a disembodied spirit, this makes a little sense.
    • Mass Effect does it often, and there's no particular handwave for it most of the time. In the first game:
      • Four of the NPC's aren't even part of the ship's crew, so it's not like they are needed on board. The other two are marines, so they wouldn't be much help in a starship battle. It's never explained why Shepard can't take the entire group of 6 with them (though in levels where the Mako is mandatory, it can be somewhat handwaved by the limits of how many can fit into the Mako). Especially when the entire universe is in the balance. In fact, the only person in the party who would have a logical reason to remain on the ship is the Player Character themself, as Shepard is the ship's Commanding Officer.
      • Especially odd during the Virmire mission, when the game explicitly shows the entire crew on the planet and ready for the battle, and the narrative points out that every last soldier is necessary for the mission. Depending on your choices, either Ashley or Kaidan will go with Captain Kirrahe, the other will eventually take the bomb, and Wrex will end up dead unless you have either done his mission or have the Charm/Intimidate points to talk him down but you'll still wind up with at least one of Tali, Garrus, and Liara totally unaccounted for. Stranger still, when either Ashley or Kaidan go to set the bomb you get the chance to totally reconfigure your party on the spot from all the remaining party members, despite the fact that you're standing in the middle of an enemy base and the ones you aren't using are nowhere to be seen.
    • Mass Effect 2:
      • At one point, the entire team goes away on a "mission", and it is explained that Shepard would then choose who to take with them when they get to their destination. The "mission" is actually a transparent plot device to get all the combat-capable people out of the ship so the Collectors can kidnap the crew.
      • Averted in the The Very Definitely Final Dungeon, where the whole team gets to participate. Although only two squadmates can come with you, the others are blasting their way through another path or holding the line while you fight the Final Boss.
      • Particularly jarring in the Lair of the Shadow Broker DLC. After meeting up with Liara, you are prompted to choose which one of your teammates to take with you, despite there being absolutely no point to leaving one of them behind. Sure, it makes some sense to leave part of the team behind on the Normandy (that would've really helped in the Collector attack), but in this case, there is literally no reason for this other than the headcount limit. Made even more ridiculous by the fact that the group of three then enters a skycar - which explicitly has four seats.
    • Mass Effect 3 attempts to justify the limited party size early on (in "Priority: Mars", James is told to go get the shuttle after Liara joins the team, just so he can reappear later and help during a crucial moment) and has squadmates being involved with official/personal business when they're not in the player's party, but the game slips back into the same problems later on:
      • In the "Priority: Cerberus Headquarters" mission, EDI essentially pushes her way onto the team by telling Shepard that she is the only one who knows the command codes for the Cerberus base and can provide tactical advice. Even though there should be nothing stopping Shepard from taking additional personnel for support (as this is an important mission, and EDI's main role is to network with the various systems), s/he elects to do the same "only bring one other squadmate" routine.
      • During "Priority: Earth", the squadmate(s) the player doesn't pick simply up and disappear, with no real reason given why Shepard can't bring more than two squadmates along to the most important part of the battle for Earth's survival. Earlier drafts of the script would have mitigated this problem, as there would have been a sequence where Shepard would have had to help one of the squadmates who was travelling with an armored infantry column during the "No Man's Land" segment of the mission, and several of the past squadmates would have been shown fighting on their own or with a group.
      • Played with in the "Citadel" DLC. When Brooks mentions it's a shame Shepard can't bring their whole team on this mission, Shepard decides to do just that. The controllable party is the same size (they're the guys taking point with Shepard), but the rest of the crew is there to provide covering fire. The radio chatter consists of the good guys loving how much ass they're kicking and mooks soiling themselves. Lampshaded again later when Joker's skycar only has room for Shepard and two others. This leaves the rest of the roster standing around, complaining about not getting picked. Amusingly, complainers includes the squad mate that the player has used the least throughout the rest of the game, the squad mate that the player has used the most, or Wrex.
    • Sonic Chronicles limits you at four with Sonic always in the lead. Counting Cream and Omega, you can have eleven.
    • True for Dragon Age: Origins as well. You'd think as one of the only two people able to stop a horde from destroying the world, you'd be able to take all your companions into battle, but you're limited to a party of four. Unlike the other games, though, during the final battle in Denerim, all your companions join the initial assault. Then you make your party selections for the final boss battle, leaving the rest to defend the gates. Kudos to Bioware for actually letting the players control the remaining companions during the defense (one of only two occasions in the game where the party does not include the main player, the other one being a rescue mission for the main character).
    • In Dragon Age II, the three-companion limit is explained for most of the game by the fact that most of Hawke's companions are established as having their own lives and things to do outside of running around with Hawke. Aveline has a day job with the city guard, Anders runs a clinic in Darktown, Varric is a writer and is implied to have other business going on as well, Merrill is working on restoring the Eluvian, Isabela is trying to track down her relic and Sebastian is working for the Chantry; only Fenris and (in the first act) Hawke's sibling seem to have nothing better to do. However, on the two separate occasions when all hell breaks loose all over Kirkwall and the survival of potentially everyone in the city hangs in the balance, it makes considerably less sense that half your friends see fit to sit this one out. At least at the start and end of the final part your entire party is fighting (as well as some NPC allies you've picked up along the way, although only three of them are under your direct control.
    • Dragon Age: Inquisition subverts this. While the three-companion limit remains, it is repeatedly implied that you're actually bringing all of them with you, you just can't use them because of Gameplay and Story Segregation. Talking to them after major quests has them speaking as if they were there, and sometimes they'll just pop up out of nowhere during the quest itself. For example, if you exile the Grey Wardens and Blackwall isn't in your party, he'll still randomly appear to ask the Inquisitor permission to stay. Additionally, characters who are not in the active party at the time may still express approval or disapproval for your choices. The primary exception to this is the Fade sequence in Adamant; conversations afterward make it clear that your chosen party members were the only ones with you.
  • Planescape: Torment is actually a fair bit better with this. The party can have up to six people, counting the Nameless One. There are only eight recruitable characters, and one of them is almost universally considered The Load, and another is a batshit insane Knight Templar who even a good aligned Nameless One probably wouldn't want.
  • In Dungeon Siege, your party is arbitrarily limited to 8 characters. Once full, you have to abandon existing characters when you want to recruit new ones. Your pack mules are included in this, so counter-intuitively your party can keep track of less animals as there are more of you.
    • Frustratingly, to a mind-boggling degree, you don't start with the ability to have a maximum-size party in Dungeon Siege 2. You start with two and have to find an NPC and purchase the right to have progressively more active party members at one time. You can't reach the real limit until you've already beaten the game twice.
      • The blow is arguably lessened to a degree due to the fact that the first 4 potential party members you come across are one of each of the four main classes (Lothar the warrior, Deru the archer, Taar the Nature Mage, and Finala the combat mage).
  • On the surface, Geneforge is generous about this, with a party limit of eight. Due to the way your Mons work, you'd have a hard time getting more than five anyway. Then again, there's also the matter of the experience penalties for large parties, which seem designed to make you not want more than eight party members anyways.
  • Might and Magic had this, though in different ways in different chapters:
    • I to V had parties restricted to six (I, IV-V) or eight (II and III), in-game creation and switching out of characters at inns, and no explanation for why a larger party would not have worked. The two extra slots in II and III could only be filled with hirelings, who would desert the party when you rested if you couldn't pay their wage from your gold on hand.
    • VI, VII and IX had a party of four, with all created at start, and reasons for them not expandingnote ... but one could also recruit up to two 'followers' that gave some perks, with no explanation given for why three followers were one too many. VIII had parties of five, with one created at start and unable to be switched out, and others found as the game progresses, but no explanation for why, once you have that many adventurers, any excess over five has to stay at the inn.
  • Ultima had this in many of the games. In Ultima IV you are limited to 8 party members and there are 8 recruitable, but the game dictates that you cannot recruit whichever NPC matches your class. ''V-VII play this totally straight.
  • Mount & Blade has a limit to the amount of lieutenants and soldiers that can be added to the party at any one time. However, this limit can be increased by raising your charisma statistic when you level up, or by increasing your renown by winning battles, and there is no upper limit on how high you can raise your party cap.
  • The Elder Scrolls V: Skyrim only lets you have one companion at a time, just like Fallout 3, and it doesn't even attempt to explain why. If you ask someone else to join you, they'll just say "Looks like you already have someone following you."
    • However, if you find and adopt one of the wild dogs wandering skyrim or meet Meeko, you can have a three man party consisting of yourself, a human follower, and said pet.
    • You can also get around it during the Dawnguard quest. Serana will follow you until you complete her quest (which is a long one and which you are not forced to complete) while still allowing you to have a proper follower. After the quest, she can still follow you but occupies the follower slot.
  • In Evil Islands, you can't have more than two allies at a time, although Lazy Backup is avoided and you can just pick another one if one of them is killed.
  • The old SSI Gold Box games generally had six slots for player characters that you'd generate yourself at the start of the game plus two more for any NPCs that might join. This generally managed not to feel overly contrived since for plot reasons such NPCs were only ever met in ones and twos for particular occasions and would leave again as soon as their part was played out, leaving those slots open once more for others (or the same character(s) again later in the game).
  • Avadon draws some obvious inspiration from the Bioware franchises above, and so runs into this trope as well. The party cannot be bigger than three people. Where this gets weird is the companion loyalty quests, in which one of your companions has run off to deal with some personal quest of theirs. If you take the usual two companions with you when leaving Avadon in pursuit of your wayward friend, when you catch up with them you have to send one of the two home because you can't have more than three people in the party. "Enjoy the walk back!"
  • Arcanum: Of Steamworks & Magick Obscura uses a system similar to Fallout 2, where the follower count is determined by Charisma (getting Expert training in Persuasion enables an extra follower slot); maxing out both Charisma and Persuasion allows recruiting followers of the opposite alignment and keeping around people who don't like each other. However, this only affects NPCs who actually care about your personality - the only limit to the number of mechanical or summoned creatures you can get is the hardware potency. Quest-only NPCs always join regardless of the limit, however, and there exist exploits that let you keep them afterwards.

  • In the Star Wars: Battlefront games, bots are limited to a maximum of thirty two per side. However modders have found that by altering a few lines of script in their mod maps, they can have battles with over a hundred troops on the battlefield at any given time. Granted, a hundred soliders on the Tantive IV would probably be overkill, but it would make sense for those large outdoor levels.
  • The ill-fated Jurassic Park: Trespasser, rushed to completion for the sake of deadlines, had to be released long before many of its reliability and performance issues could be resolved. Lots of cool ideas were abandoned, along with one entire level, because they just couldn't get them working in that amount of time. The quick fix they introduced to minimize, at the very least, the rampant in-game slowdown? They coded in a hard limit on the number of dinosaurs the engine could generate per level. Seven. Of any kind, hostile or non-hostile, something you have to fight or something that's standing off in the background and completely irrelevant. The total can't exceed seven.
    • Within a certain distance. There can be more than seven, but they just stand there, being invincible and doing nothing until you get within the required distance. This makes long range combat even more infeasible.
  • In Operation Flashpoint, squads are limited to twelve soldiers at a time, including the leader. This is due to technical limitations: squadmates are selected with the function keys. The AI is also affected by this as the mission editor won't let you link more than twelve soldiers into a squad.
  • "Tactical" shooters like Rainbow Six or SWAT 4 give you long, impressive-looking rosters of potential teammates to aid you in your missions... then limit you to a small squad of operators regardless of the size of the level. Particularly glaring when you're asked to clear large structures - cargo ships, oil rigs, warehouses, hospitals - with less than 10 people.
  • Postal 2 has a form of this - there is an option to limit the amount of people spawned in one map area at a time, to prevent overloading and causing the game to crash. Depending on the player's setup, one can increase that number for more carnage.

    Simulation Games 
  • Many combat flight simulations, such as B-17: The Mighty Eighth or IL-2 Sturmovik have a limit to the number of planes in a given scenario. This means that the player's 3 or 4 fighters are typically attacking enemy bomber formations of 8-12, rather than the 80-100 common in the Battle of Britain, with predictably catastrophic results for the bombers.
  • In The Sims 2 and The Sims 3, you're only allowed to have eight Sims per family. The game still works just fine if you use a cheat to raise the limit. (Adding to the arbitrariness, pets count, even though they take up much less space and player effort than human Sims. For example, a couple with six children couldn't get a dog.)
    • Modifications have also been released that alter this limit. One even allows you to go all the way to fifty.
  • Aerobiz: The first two games limit your airline to no more then 40 total flight routes. Frustrating in the second game due to how the region system works and the fact that there are about 90 or so cities in the game.
  • The iOS game Dangerous has a Hand Wave for this. When your Player Character first asks about wingmen, she replies that you may only take two with you into battle, while the rest hang back and gossip. When asked why, she claimed that your ship's nanocomputer must interface with the others. Attempting to do this with more than two other computers results in some very unpleasant temporal paradoxes. When asked if it's a joke, the computer is offended.
  • Each Animal Crossing game has a maximum number of animal villagers who can live in your town: 15 in the original, 8 in Wild World, 10 in City Folk, and 10 again in New Leafnote . In all of the games, a maximum of four humans can live in the town at once.
  • In Dwarf Fortress, Adventure Mode places a limit on how many companions you can recruit, based on social stats and fame. Meanwhile in Fortress Mode, your fortress population has a cap that the player defines in the setting files, though it isn't strictly adhered to.
  • Your spaceship in FTL: Faster Than Light can hold a maximum of eight crewmen; if you get one more than that, you will be forced to dismiss someone. Justified since in real spacecraft design every gram counts, including those of spacemen.

    Strategy — 4 X 
  • The older Civilization games had an Arbitrary City Count Limit (255 for Civ 2, to be specific). The table of cities only had room for 255 entries.
    • Civilization IV forbids each civilization from having more than three missionaries of a given religion at any given time. However, since missionaries are self-consuming (you send them into a city, order them to spread the faith, and whether they succeed or not that's the end of the missionary), the limit is not nearly as annoying. Certain mods included with the game (notably the Next War sci-fi mod) also use this concept on certain extremely powerful units. The vanilla version of the game also limits the number of national wonders a single city can have.
  • Sword of the Stars doesn't limit the size of the fleets, but it does limit how many ships that can participate in a battle at each moment. Each side gets command points based on on the size of the command ship (if any), some technology upgrades, and if they outnumber their opponent; when a ship gets destroyed (freeing up associated command points), new ship(s) will arrive as a reinforcements from the reserve. You are also limited to only one flagship-type dreadnought.
  • Stars! has a few limits mostly related to variable sizes and its reliance on 16-bit Windows - 32,767 of any one ship type in a fleet, 512 separate fleets, 512 separate minefields, and 256 tokens in a single battle. In games with a large universe that might last a long time, these limits could be reached and be exploited. For example, the 256 tokens in a single battle could be tweaked to keep vulnerable bombers or freighters out of a battle at a planet.
  • The first Imperium Galactica game caps the size of an individual fleet at 28 capital ships and 180 fighters, and fleet flagships can only carry a limited number of tanks for planetary assaults. However, the former cap can be easily circumvented by merging fleets. The sequel drops the fleet size cap and removes flagships; each capital ship now has its own tank limit.
  • Since Sorcerer King lacks a gold resource for unit upkeep, it instead has "logistics", a straight cap on the amount of units you can produce at your cities and have on the field at any one time. Note the wording - units not deliberately produced (such as quest rewards) don't have a logistics cost. Logistics as a hard cap to raise, so this distinction is vital.

    Strategy — Real Time 
  • In Homeworld, there is a limit as to how many ships can be built by your own ship construction facilities. This could be explained with Fleet Command being unable to direct more at one time, or not having enough crews to man more vessels, if it weren't for the fact that one can go far beyond this limit by capturing enemy ships and adding them to one's own fleet.
    • However, in the sequels, breaking the headcount limit is stopped: all ships, captured or built, are counted under the fleet cap (and a capture that failed because of this didn't even have the decency to scuttle the ship).
    • Moreover, the limit is on ships of a given size - 50 fighters of any kind, xx corvettes of any kind, 18 frigates of any kind, 4 destroyers, 4 carriers, and three cruisers) - which could lead to not being able to build more fighters but being quite capable of building a whole pile of corvettes that would all be turned to scrap metal in under three seconds.
      • Except one: Hiigaran Mothership/Vaygr Flagship. It is possible (as far as official 1.1 patch is concerned) to have a 6-player match and ending up with each player's flagship as your own. Didn't See That Coming did you?
    • Homeworld is one of the few games where going above the arbitrary limit is likely to cause more grief than benefit to the player. The size of the enemy fleets one encounters during the levels is calculated depending on the size of your own; if, by capturing or editing the game files, you start a level with a supermassive fleet, you'll be fighting a *lot* more enemies. Also, your fleet begins every level by hyperspacing in in a straight line. Have enough ships and the line can extend further than the game ever assumes, triggering events that shouldn't happen until later in the level.
  • In the Warcraft games, one must build farms in order to have units, with the limit increasing with the number of farms built. The rationale for this is that the units need food. Yet sometimes one starts a scenario without any farms at all, or an inadequate number to feed one's troops, or your farms in a normal level get destroyed. Said units suffer no ill effects for this.
    • In Warcraft II there is a hidden limit of 600 units (and buildings) divided by the number of players. (Meaning only 75 per player in an eight player game.) Extraneous units simply disappear when their construction completes, wasting resources.
    • In Warcraft III, there is also a global supply limit of 90 (raised to 100 in the expansion) on the total number of units a player can train (although it is possible to go over this limit if the extra units are acquired via means other than training, like resurrection spells or a scenario script). Unlike Starcraft, there is only one supply pool (as opposed to a separate one for each race), and the limit thus cannot be circumvented by building units of different races.
      • Most units require between 2 and 5 supplies in this game however, limiting a normal army to about 20 units at most.
      • It's also worth noting that if you want a higher supply limit (assuming it's a non-campaign map), changing the Game Values is possible, though it only goes up to 300. However, the game's engine can't seem to handle more than about 250 units per player— if more are generated through scripts or other tricks, movements become very erratic.
      • You can also change the supply requirements of the units, including setting them to zero.
  • In Starcraft, one could only have a maximum of 200 supply worth of units on one's side; if you tried to make another after the limit was reached, it simply wouldn't work. However, in the Expansion Pack, Starcraft: Brood War, the "Dark Archon" could capture the other side's worker units, thus allowing you to create buildings and build up to 200 of each of the three races in the game.
    • The Dark Archon can also capture units in excess of the Arbitrary Headcount Limit. In a team game, it is possible to exploit this to create a ridiculously huge army; Player A cranks out unit after unit, while player B methodically seizes control of each unit with Dark Archons. Not usually a very effective tactic (most games are over long before anyone hits the cap), but amusing.
    • The Unit Limit in Starcraft was put in place not as a balancing factor, but to prevent players from building units in excess of what the game could process. Despite this, it is possible for a Zerg player to force the game's memory out by building Overlords (the only unit in the game that does not use up supply) en masse, causing units to stop spawning when the game runs out of memory. Not a very useful tactic in high-level play, due to the tendency of games to end quickly, and the resource limit imposed by most maps.
      • It's also possible to construct so many buildings that the game won't allow any more units to be built (or any more buildings, for that matter)— discovered when using Dark Archons to sieze an ally's Carriers; additional Interceptors couldn't be built until some building were razed.
      • This has been an issue with Terran Valkyries as well, who shoot several missiles in a broad area. The missiles can sometimes not fire because of the aforementioned technical limitations. This was cited as a reason, though not the main one, for the lack of Valkyries in the Metagame.
      • With the use of cheat codes, it's possible to make the game crash itself in missions where the AI receives infinite units after an event trigger. Try using "Staying Alive" on Terran Mission 9 in the first game.
    • It sure wreaks hell on a great many Use Map Settings games featuring trigger-spawns of many units, and hundreds of buildings across the map. The "Cannot Create More Units" is so bad in maps like "The World in the 1800s" that the game literally begins to drop players en masse.
    • Starcraft II has the Protoss Mothership, a unit which uses no normal supplies, but of which there can only be one at a time (per player), or which can be built like any other unit (i.e. as many as you can afford) but costs a metric fuckton of resources - Blizzard is still working on that.
  • In the Total War games, you can build as many units as you want, provided you can maintain their upkeep. However, in battle, you are limited to twenty units per army stack. On the maximum scale settings, this can give you a maximum of 4800 soldiers to command in a single battle. In Rome: Total War, this is a bit of Fridge Brilliance, since that number isn't far off from the total number of fighting men in a Roman Legion. (Not counting the thousands of support soldiers)
  • The Total War series feature two such limits : the armies in the first two games couldn't have more than a given number of units (with the exception of crusades and jihads in Medieval, that could have 4 times the standard number, however only standard-number units could take part in battles at the same time, with the rest trickling in as reinforcements over the course of the battle when other units were killed off or routed off the map). The third and fourth game feature both this unit limit, but also a limit to how many individual soldiers can be in one army regardless of the unit count. To be fair, the soldier thing is more of a technical issue, and can be expanded by tweaking the game files.
  • Every Age of... game had a headcount limit. This is particularly ridiculous, since the Age of... games are supposed to portray great battles of times long gone, which were normally conducted with hundreds and hundreds of men. The first Age of Empires had a unit limit of fifty! However, it is possible to convert enemy units using priests to go indefinitely beyond this cap. Additionally, all units built before the population limit is reached will be completed regardless. Employees of Ensemble, the company that developed Age of Empires, were famous for building, for example, 20 barracks at 49/50 population and queuing each building to produce one soldier, which gave them 19 units over the limit.
    • In the original game's expansion set "Rise of Rome", the technology "logistics" allow infantry to count as 1/2 a unit, thus allowing a larger army. The basic head count is also raised to 75.
    • This can be extended to 200 per player in the multiplayer mode (since each unit counts as 1, this limit is almost never reached), and the amount of units placed in the campaign editor is limited only by the power of the computer running the game.
    • Age of Empires III also includes headcount limits for certain unit types, most notably ships. Most Civs have a generous cap of 99 Settlers (half of your population cap), although the Ottomans, who produce Settlers automatically and for free, have a more substantial cap of 25 until you raise the limit via certain techs.
    • Certain special units have a Limit of One. Most notable is Age of Mythology, which has several of these units, including the Titans, the Hippocampus, and a few others. In one case, the clever combination of an Egyptian technological upgrade (allowing two Pharaohs) and a cheat code (allowing reuse of a god power that transforms a pharaoh into a lightning-wielding Son of Osiris) actually allows the player to create an infinite number of Sons of Osiris, provided he has enough houses for them all.
    • Age Of Mythology added a new feature to screw the headcount even further: some units take more space from the population slots than others (i.e. a villager or a simple soldier takes one; a siege weapon or a mythological unit can take up to five).
      • The game features a rather flexible limit, though. Every player can build houses for 100 slots and as many Town Centers as he can get a hand on (they can only be built on specific spots). They provide 25 slots each if upgraded, and a certain relic allows them to give 3 more, while the Citadel god power adds 10 slots to a town center, in addition to making it much harder to destroy.
      • The final max Arbitrary Headcount is 300, as can be demonstrated in the final level of the original campaign by building on as many locations as possible. We Have Reserves indeed.
      • There are also hard limits on the number of each type of building you can have.
    • Units/buildings that can carry other units inside them, like Transport Ships, also have an arbitrary limit, usually 10 units. Combines with Units Not to Scale to produce the rather odd fact that 10 elephants fit in a boat, but 11 infantrymen don't.
  • The Command & Conquer series is notable for having no such limit, with the exception of a port on the Xbox 360, and some "Hero" units which are limited to one for each team.
    • Up to Command & Conquer 4, where one of the features include... a headcount limit.
      • Strangely, said headcount limit was variable between missions (even in skirmishes!), though you were usually limited to 60 points, and could break it by commandeering fallen enemy heavy vehicles. One upgrade brings your dead heavy vehicles back to life, even if that puts you over the limit. Build five Mammoth tanks, kill them, build five more and wait for the other five to come back to life, you've got ten, and you can repeat until everything else is dead.
      • The headcount limit comes up in Tiberium Alliances, where even the buildings have a limit.
  • Rise of Nations was fortunate to have a comparatively huge Headcount Limit of 250 units, which could be raised to 320 with the right combination of civilization (Bantu) and wonders (the Colossus). Some units, of course, count as two heads, but it still allows for some really, really big armies.
    • And that's assuming you don't mess around with the config files.
  • One of the earliest RTS games, Dune II, uses this as well — however, in this case, the explanation could be the very real technical limitations of the PCs and Amigas the players of those days possessed. In its sequel, Emperor: Battle for Dune, the headcount limit was lifted.
    • It was also lifted in the remake, Dune 2000... but they forgot to update the AI to compensate, causing a bug where taking too long to make an attack against an enemy would cause them to have an army so vast that victory was impossible, as they were perfectly efficient at building units, and never stopped, expecting to run up against a hard-coded cap that no longer existed.
    • The original also kind of screwed up its limits. While you couldn't build anything beyond a limit of 25 units, you could Starport in anything up to a total of 99. This basically meant that your later armies consisted of about two Devastators (which can't be bought) and ninety-seven Siege Tanks (which can).
    • Incidentally, in Dune II, a similar limit existed for buildings. This was actually rather exploitable, since the building limit was global: if you reached the building cap, then you could prevent the enemy from rebuilding by destroying one of their buildings and immediately replacing it with one of your own.
  • Total Annihilation was released with a unit limit of 250 units per side. A patch was released that raised this limit to 500. The large modification community for that game had even found a way to increase the unit limit to 5000 units per side. Given that the game allowed for easy adding of new unit types up to 256 different units, 512 with a community made fix, that means you couldnt build one of unit avaible.
  • Supreme Commander, TA's spiritual sequel, has a default limit of 500 in multiplayer/skirmish games. It can be increased up to 1000, and also decreased to 250 (for the unlucky ones whose computers can't handle the amount of units in a capped-to-500 game. This tends to be particularly annoying in the last campaign missions, some of which start you off with 300 or more units and a maximum cap of 500. Editing the game files can theoretically increase the unit limit to arbitrary numbers, but the frame rate really starts suffering (even on high-end systems) after 800 or so, and going much above 1000 is guaranteed to cause a crash.
    • In Supreme Commander everything you build (except walls) counts as a unit- not only tanks and aircraft, but power generators, point defence and radar systems.
  • The Pikmin series of games caps the total number of Pikmin on the field at any one time at 100. If you try to spawn any more the main character notes that the Pikmin "refuse to come out."
  • World in Conflict has a variation of this, every player has a limited pool of reinforcement points to buy units with. Different in that losing an unit doesn't allow you to replace it immediately, the reinforcement points are instead regained slowly. Paratroops and light tanks ordered as tactical aids rather than as reinforcements for some reason don't count towards this, though.
  • In Warzone 2100 each player (a game can have up to 8 players) is allowed to have 300 units (though only a dozen or so trucks - the game's worker unit - are allowed). That cap is several times higher than the AI and pathfinding is able to handle though, resulting in that in long matches with several players on big maps, some units are unable to move or take minutes after being issued an order before they actually carry them out, and clouds of attacking VTOL bombers can slow even the fastest computer available to a crawl.
  • Also seen in Company of Heroes. This is mostly done to prevent tank-zerging (which is still possible to a limited extent). Your population cap is dependent on the number of resource points you control. If your cap is reduced, existing units do not suffer, but cannot be replaced.
    • Certain units are also capped; you can only ever deploy a single King Tiger to the battlefield in a game, and it costs an insane amount of resources to deploy as well as a considerable amount of your population cap.
    • US Armour players are also limited to 1 Pershing at a time, although replacements can be deployed. The Pershing is much weaker than the King Tiger however.
    • The same is employed on several defensive emplacements to reduce the effectiveness of turtling. A prime example is the German factions, who can deploy devastating Flak-88 anti-tank guns. They are effectively forced to choose between having an offense and a defense.
  • Empire Earth was pretty good about this; although it did have a unit cap, it was a unit cap for the entire game you were playing, and you were allowed to set it along with the rest of the game options. This meant that players with slow machines could have lower unit caps to compensate, while players for whom it didn't matter could have a max cap of 1200. Mind you, this was for the whole game, but even with the games maximum 8 players , that's still 150 units to play with. The game even had a building ingame that allowed you to steal a portion of everyone else's cap and add it to your own.
    • There was also a building that was used solely to contain up to 40 of your units, then return them. When inside, they are removed from the limit, but not from the game. So if you had the ressources, you could attack with an obscenely large numerical advantage.
  • End War hardcaps the units on the field for any given side to 12 - while also only allowing 6 infantry units, 2 artillery, and 1 command vehicle, as well. No real explanation is given for this.
  • Star Wars: Empire at War and its expansion are interesting with this. There is both a population cap and a reinforcements cap. The population cap increase with every planet captured and every Space Station built and/or upgraded. The larger and more powerful a unit is, the more population it takes up (but heroes always take only one point). However, the tactical battle cap is different. In Space Battles, one can bring in 20 (Empire) or 25 (Rebellion) points' worth of ships, with each starship/fighter squadron/hero requiring the same amount of points they require in the Galactic Map. Land units always take one point (but most consist of multiple troops/vehicles), and there's a different system: the defender's limited to ten units, while the attacker is limited by the number of Reinforcement Points they capture; each contains a different number of points, and they are still limited to ten population points.
  • Sins of a Solar Empire has this in spades. Your total number of ships is capped by a number called "supply", with different chips accounting for different amounts (a scout frigate might need 2, while an assult corvette could be 7 or 8). This limit starts out at 100 and can be increased with research, though doing so increases the upkeep deducted from your resource income. Then there are capital ships, which need a whopping fifty supply, and are limited by how many crews you have avaliable to man such sophisticated ships, which can again be increased with research. Each planet can also support only a limited number of logistic and military structures, and while this can be increased on a planet-by-planet basis, the highest possible cap is determined by planet type (a fully-developed asteroid can support fewer structures than a fully-developed terran planet, for instance).
    • There is one exception to this rule. The Advent Rapture capital ship has an ability, Dominate, which allows it to takeover enemy ships except capital ships. Used over a long period of time and without sustaining massive casualties, an Advent player can have a fleet that exceeds the capacity. However, the caveat is that you're unable to build any ships until the limit goes back into positive numbers.
    • Each player can only build one Titan-class ship. Even building one is an enormous investment in resources and time, and all other players are notified the moment you start building it and where the shipyard is located.
  • The Warlords Battlecry series has no arbitrary limit: you can build as many units as your buildings + charisma + upgrades provide room for. However, the games do have a tendency to crash, especially as the number of units on the map increase, so building ludicrously huge armies is generally not possible before you suffer a precipitous crash to desktop.
  • In Little King's Story you can only have as many troops following you as you have badges for them. Apparently, no one's going to fight for a king that doesn't hand out shiny badges.
  • Star Wars: Rebellion has "maintenance points". Every planet you control gives you a certain amount of maintenance points. Planets also generate raw materials in their mines. Raw materials can then be refined with refineries; you have to pay a one-time cost in refined materials, but it also takes maintenance points, which return to you after the object is destroyed. You're further limited to eight groups of capital ships and four groups of starfighters. But that's not an actual limit on the size of your fleet; it just means you start having to conflate different ones. (In the case of starfighters, they're typically arranged by model, with the most popular model being split into two or three (or if all that model, four, as can happen when you're the Empire and your only decent fighter is the TIE Defender) groups. Finally, you can only have one Commander, Admiral, and General in a given fleet.
  • Warhammer 40,000: Dawn of War likewise has a max limit for the number of units that can be requisitioned (similar to the point system used to limit the size of armies in the tabletop war game it is based on).
    • Furthermore, the Expansion Pack Dark Crusade takes this concept further by limiting the availability of certain of the more powerful units in the game to a number below what resources and the regular "unit cap" would allow for (though such units may still be purchased and queued up to be fielded, once the original units are lost). Again, in many cases this is based on field allowances in the tabletop version. For example, the Imperial Guard is limited to having two of their Leman Russ main battle tanks on the field at a time - ie by real-world measures you are only allotted half a platoon even for the most important battles.
      • This also makes the game harder for some factions. For example, the standard infantry doctrine of the Imperial Guard is Death of a Thousand Cuts, as Guardsmen are too weak to fight melee. They need something to keep the enemy at bay to Beam Spam the enemy with their lasguns - the only thing they're good at is to Zerg Rush the enemy with ranged attacks. Ogryns assisted by a Priest are perfect for this task - but in Dark Crusade, Ogryns are capped at one squad at a time. If the entire enemy force is concentrating their fire on the Ogryns, the meatshield will be gone long before the Guardsmen can put a dent in their targets. This can be horribly jarring to players who got used to Winter Assault's capless units.
      • As a rule of thumb, every unit beside basic ones is capped. High-tier units (even ones that don't need relics) are usually limited to one at a time. This makes Assault Terminators nigh-useless as they die too quickly (since they're melee-only, they are always the ones at the front of the army and thus, the first ones targeted but they don't have enough HP/armor to take massed firepower).
      • In at least one level of said expansion's single player campaign, it is possible to circumvent these caps by exploiting the enemy's use of a weapon that puts units within its range in temporary stasis: once a player loses control of his units, they do not count towards his army total so long as they remain that way, and so further units may be built to "replace" them in that span of time.
      • The most impressive case of all, however, is the practice of building and killing as many Necron warrior units (in the same place) as the player can be bothered, and then using an upgrade for the commander to revive all of them (allowing armies of at least twice the pop cap). This is helped by the fact that a basic squad of warriors - 3 - costs nothing. Which was why they capped it in the next (and somewhat disregarded) expansion, Soulstorm.
      • One of the Game Breaking Bugs in Soulstorm is that, if an enemy Essence of the Deceiver briefly converts a player's capped squads to the Necron side, a fast enough affected player can build another of the affected squad type and retain use of it even after he regains control of the converted units.
    • This trope hits much harder for the Space Marines inside Dawn of War 2's multiplayer - you'll generally be able to have around 8 infantry squads for them, or more likely around 5 if they are upgraded with a sergeant. The standard squad size for the them is 3, potentially 4 if you get a sergeant. With a cap of 100 population with generally 5 for one Space Marine squad member, needless to say, you won't have many men out at one time. Other races may have around two or three times as many for their infantry squads at the same rough cost, however. The most infantry one may have at one time in the multiplayer is 98 Rippers for the Tyranids. But, Rippers are pretty much Redshirts, so don't expect much from such an army.
  • Populous: The Beginning had your tribe limited to 200 followers. An exploit allowed players to exceed this, but this could lead to game instability.
  • The maximum amount of troops that you can train in Clash of Clans is directly proportional to the maximum space that your Army Camps can house (240 at maximum).
  • Subverted for military units in Europa Universalis 4, where both the land and naval force limits are soft limits: you can go over it, but you'll pay an increasingly higher maintenance per unit, due to lack of administrative infrastructure. Played straight, however, with advisors: you can only have three employed at any time, one for each tech category, with a similarly limited number of advisors available for hire. The latter cap can be increased with certain buffs, however.
    • Justified in another Paradox game, Victoria 2, where how many troops you can keep in the field is related to your population, specifically your number of soldier pops.

    Strategy — Turn Based 
  • Final Fantasy Tactics, though listed partially as a Role-Playing Game, does give the player the ability to hire new recruits, in addition to the plethora of warriors who are constantly joining your party. The game allows space only for a limited number of troops in one's party. On one hand, this makes sense, as it would be impractical for game space as well as time spent on training a large army of troops 4 or 5 at a time in battles (the allowed number per skirmishes). On the other hand, sending a dozen or so warriors against the ultimate evil does seem a little low on firepower, and makes one wonder if anyone truly cares about the state of the world. (See Apathetic Citizens.)
    • In Tactics Ogre in that respect: the player can form parties of ten soldiers, the only limitation being that only two L-class soldiers (such as Golems and Octopi) are permitted.
  • The Advance Wars series of turn based strategy games has an arbitrary cap on the number of units you can build (50), but it's high enough that it's very rare for anyone to actually reach it.
  • Fire Emblem has a limited number of deployments per chapter. It changes each chapter as to how many troops can come with you. A few of these they will make a passing mention of how this is supposed to be a 'low key' attack or how only so many people can pass, or the others are guarding something. In general it's just to make it challenging, as Fire Emblem is Nintendo Hard. Although 9 and 10 try to justify it as a Vanguard. Averted in 4, where the player could field every unit (somewhat necessary, as the maps were HUGE, not to mention that the game had far fewer units to choose from than do the other games in the series).
  • Super Robot Wars follows the Fire Emblem model, and typically by the end of the game you'll have at least two or three times as many robots sitting on the sidelines as actually participating in a fight. The exceptions are the squad-based games, Alpha 2, Alpha 3 and Z, which group up to three or four robots into a single squad and then let you deploy of to 20 of those, allowing all or almost all the player's forces to participate in many battles. The "pair-based" games do the same thing, though on a slightly smaller scale, deploying two characters in one controllable unit.
    • This limit is pushed to the extreme in the Super Robot Wars Z2 games, which include a whole game's worth of a new cast, while including every included series from the first Z. While only around half or less of the previous game's cast return, it does include all the best units from each series. However... There is no squad system. The result is well over 100 deployable units, and enough deployment slots for around a quarter of that, until getting the extra slots during very last stages. You cannot even deploy a single character from each series without hitting the limit.
    • Worked around, in Super Robot Wars W, where your ships could gain the ability to switch out active and reserve mecha during battle. The game also had the "Support Request" ability, which allowed characters to call in a reserve character for a supporting attack, as if they had been right next to them the whole time.
    • In Mugen no Frontier, out of seven units, only four can fight, but the other three can do Support Attacks, which can be helpful - maintaining combos, finishing weakened enemies without wasting a turn, and increasing the Frontier gauge as a bonus.
  • In the Shining Force series of games you were restricted to the number of people in your "army". Thus you normally ended up with an army of twelve which the enemy army had well over 30. In game mechanics this made sense but in plot line when you're about to fight the Big Bad it doesn't make a lot of sense not to use all your men.
    • Shining Force III had a battle in scenario 1 had your force split into two. The primary group, whom you had been playing with all game and so were all ridiculously high levels took one force, leaving the secondary group filled with characters you used once and discarded to take on the roughly same size force in a separate battle that determined when the primary group could stop fighting an unkillable killing machine.
  • Nippon Ichi games generally have limits:
    • The Disgaea games limit you to ten on the field at once (though you can switch between them). There is also an arbitrary limit on the amount of specialists you can put onto any given item in the Disgaea games, based on rarity.
    • Phantom Brave limits you to 16 units, including weapons, and the characters also have an Arbitrary Time Limit (Ivore Island, Marona's home, has an Arbitrary Limit of 50 Things, whether that be items or Phantoms).
    • Makai Kingdom allows a work around which then ends up running into a headcount limit anyway. You still have a limited number of characters on the field, but you can send in warehouses full of additional people, and then throw some of the foes into the warehouses to force them to try fighting all of the friendly people inside. These warehouses could have so many units that you could have situations where you had sheathed your weapon to pick someone up and couldn't take your weapon back out again because it would go over the limit to have the weapon displayed.
    • Soul Nomad & the World Eaters limits your number of units by "rooms"; each room holds a number of troops in a neat squad. The rooms are kept in a pocket dimension Gig created (with considerable ease, he claims) and the number of available rooms only increase by the progression of the plot, not any expenses made by you. Technically Gig should be able to give you all the rooms you need right away, although his being a card-carrying Jerk Ass might explain it. (And the fact that he'd much prefer if you just took his friendly offer to share his immense power... cue Bad End.)
  • In Luminous Arc, the character limit is 8 characters maximum in battle.
    • Luminous Arc 2 changed the limit to a maximum of 6 characters that can be deployed into any single battle, unless otherwise (generally at a smaller number).
    • Luminous Arc 3 followed the previous game with the 6 characters limit.
  • Ogre Battle allows you only ten units at a time, and each unit can have 5 characters, but a large character (dragons, monsters, golems, giants, or some demons) counts as two.
    • Tactics Ogre has perhaps one of the largest player parties outside of real time strategy games, at ten party members during battles. And when one includes any potential Guests adding to the roster, it can be even more. This leads to one battle early in the game where you just disgustingly outmatch the enemy, since you not only have your ten party members, but Kachua, Vice, and Leonard...against just little old Nybbas, two Mooks, and a couple undead that die easily.
    • Its Gaiden Game Knight Of Lodis also has a cap that exceeds the maximum battle limit, but this is likely because not only is it a strategy RPG, but there are two parts in the game in which you have to split up and attack from two sides at once.
  • In Cross Edge you get a rather large cast of playable characters from different games, but only four can be in battle at any time. Granted you can swap out characters (even dead ones) for other members of the in-active party, except for some plot battles that require certain party members to be in at all times, you are still only allowed four in the battle party.
  • Hogs of War never lets you control more than five pigs at once, with some missions in single-player and most multi-player battles limiting you to less than that. Multi-player deathmatches are interesting, as thanks to respawning you'll always have the maximum number of pigs - no more, no less.
  • Wild AR Ms XF allows a maximum of 8 units on any map, sometimes less. You can create as many Player Mooks as you want, though.
  • XCOM: Enemy Unknown limits your squad to 4 members, later upgradable to 6, and a single Skyranger, allowing you to only respond to one crisis at a time (while the aliens are smart enough to perform three simultaneous attacks). Apparently 6 soldiers in 1 plane is enough to defend the entire world from a hostile alien menace.
  • In Genjuu Ryodan, the player and the opponent can deploy a maximum of 20 units at any time. The player is also allowed only 20 out of 65 different types of units to be summoned, but player can repeat cleared missions to regain specific units needed when they are discarded.
  • In Call of Cthulhu: The Wasted Land, there are five main characters taking part in the plot and who must survive, and a sixth one who is a kind of expendable overcompetent Red Shirt. Between levels, you have the option to hire other troops, but only to replace losses, and you can't have more than six Investigators at a time.
  • Averted in Zone of the Enders: The Fist of Mars, for both the main characters and enemies. Only the plot dictates whether or not anyone is absent from any given stage.
  • North and South limits armies to a maximum of eighteen infantry, nine cavalry and three cannon.
  • In the Telepath RPG series, you can deploy more characters at once by increasing the Player Character's Personality stat, but it still caps out at 8.
    • In Telepath Tactics, the limit is keyed to individual maps. In the campaign, you are usually limited to 8 characters, though the final battle allows 12. There are two exceptions to this: the "defend the camp" battle, where every unit you've recruited is deployed automatically, and the fortress outer wall battle, where Teresa and Phoebe are automatically deployed in addition to your usual 8.
  • Averted in the first Project X Zone game. Everyone in the active party will be on the field. Even if the group is separated, they'll just start on opposite ends of the battlefield. Only if the plot says people are really separated (we're talking dimensional travel here) will you be working with less than a full headcount. The second game plays this straight and generally lets you only choose 10 characters to use per level, with only a select few stages letting you use the entire cast.

    Survival Horror 
  • Resident Evil Outbreak, both installments, only allowed four players to play together online, despite the fact that "Outbreak" (the first scenario) proves in the intro that all eight characters were together at the time. Offline it's even worse, as the player is only joined by two AI partners. A fourth occasionally shows up, but they exist only to be killed during gameplay.
  • In the original Corpse Party for the PC-98, there are five party members. Though they start out together, they're quickly split into a main party of three and a secondary party of two, the latter of which stays behind where they think they're safest, only to end up separated from the others, at which point they spend most of the game simply trying to get back together. Once they've finally reunited, it's time for the Final Boss — the only fight in the game — and the player must select which three survivors to bring into the battle.
  • ObsCure features five playable characters, but only go around in groups of two at a time (characters that die are permanently dead). The rest of the playable characters usually just wait in a central area.

     Visual Novels 
  • The Zero Escape series enforces this, and averts Never Split The Party on the characters. To go through each puzzle room, the characters have to obey rules imposed by Zero. Failure to comply will result in their immediate execution. Also, there has to be 9 players for each game to work.
    • Nine Hours, Nine Persons, Nine Doors has the loosest ruleset because Zero knew that the Ninth Man would break the rules and made an example out of him. Between three to five players are needed to open a door and the bracelets can only be opened through having the sum of their bracelets add up to a digital root of the door they're going through. Should more or less people go through the door their bracelets will activate bombs inside their stomachs. Ace capitalizes on this when he tries to murder who he thinks is Snake, using the Ninth Man's bracelet, his own and his victim's to open the door then shoving his victim through, allowing his victim to suffer a penalty.
    • Virtue's Last Reward is much stricter. Each round has the players designated colors and six of them are split into pairs with the same color bracelet. These players must combine their bracelet colors to make the colors on the Chromatic Doors, either two separate colors or one color which contrasts the door (for example, if the door is Magenta then either the GREEN players, a RED solo and BLUE pair or BLUE solo and RED pair can go through). Also, the doors open automatically and failure to go through will result in a penalty execution via lethal injection and this forces three players to go through a door each.
    • Zero Time Dilemma has three people in a team, but there's no choice in the matter - Zero has split the teams up and is forcing them to compete against each other in Decision Games. Except that one of the teams has four members instead of three...

     Wide Open Sandbox 
  • Grand Theft Auto: San Andreas. No matter how much the cut-scene emphasizes the importance of the current mission, if your respect level is low, your allies won't go with you.
    • You do get a huge amount of respect from doing the missions though, so you should have a more than big enough gang to help out.
  • In both Grand Theft Auto: San Andreas and Saints Row, you can only bring so many gang members along with you at a time (8 in GTA, 3 in Saint's Row). However, you can only fit so many into a car, and the NPC gangbangers in San Andreas didn't know how to drive. In Saint's Row 2 on the other hand, they'll hop into the nearest car and follow you, which sometimes may be a Police APC.

Non-video game examples:

     Card Games 
  • The Yu-Gi-Oh! Trading Card Game is a rather... alternative version of this. There are several rules for constructing one's Deck, and they change quite often to fit the newest anime-rules. Currently, there must be at least 40 cards in a deck, 60 at most, and a player can only have 3 copies of each card in their deck, regardless of how many cards they have. Then there's the Extra Deck and Side Deck (the latter of which only serves as extra cards to switch with between matches), both of which are currently limited to 15 cards, though originally, the Extra deck could have 30 and the Side Deck was unlimited. And just to add to the arbitrarity of the rules, some cards are Semi-Limited, Limited or Forbidden, reducing the maximum number of copies you can use by 1, 2 and 3 respectively. Yes. That's right. The producers have made cards that are so powerful nobody is allowed to use them. And then there are some rather less potent cards on the Forbidden List as well (That's right, Witch of the Black Forest. Why are you still on the Forbidden List when Sangan is allowed despite being more useful?). A few of those cards, however, only remain on the Forbidden List because their OCG-versions are still utterly broken.
    • Then there is the other limit: 5 monsters, 1 field spell, 5 other spell/traps. And now, 2 Pendulum cards. All of these are limits for what can be on your side of the field.
  • Magic: The Gathering has a limit of of four copies of a card in a deck. Early in the game's history, people won tournaments with decks of twenty Black Lotuses, twenty Channels and twenty Fireballs; the somewhat-arbitrary limit of four was decided on as a reasonable compromise between flexibility and cheese.
  • The Defictionalization of the card game from Vanguard has a maximum of four copies of anything, a maximum of four Heal triggers, and exactly six slots on the field: your vanguard, two front rearguard, and three back rearguard. You cannot, under pretty much any circumstances, have more than these six creatures active. Of course, you can retire any creature other than your vanguard at any point during your turn, much like deleting a worker in a strategy game so you have room for another giant stompy robot.
    • Link Joker users take full advantage of this. You can only attack with the three units in the front row, and Link Jokers special Lock ability makes not only a unit useless, but the circle it was standing on as well. The only way to make a locked unit usable is either waiting for the end of your turn, or using a niche unlocking skill. In short: Lock the front two rearguards, and your opponent can then only attack with their vanguard this turn.

  • In The Rithmatist, there can only be so many Rithmatists at any one time. So a new Rithmatist can't be created until one of the old ones dies.

  • Ancient Greek theatres had a limit of up to three actors on a stage at once. Much of this had to do with requiring plays that could be performed with a cast of only three main actors. (Or in some early Aeschylus works, two.)
  • In many sports, having more than a certain number of players on the field is a penalty.
  • Treaties limiting the amount of certain classes of warship the parties can possess at a time have a similar effect.
  • Many public buildings have signs to the effect of "Occupancy by more than X persons is dangerous and unlawful", for safety reasons. You don't want an excessive throng of people clogging each other up from escaping the building in an emergency.
