* Some email processors will, if you write the words "Attached is/are..." without giving an attachment, ask you if you want to attach anything before they send it. This is quite useful (or annoying if you're a high school student trying to use an excuse other than "the dog ate it").

** when Malik uses his Eternal Serenade Mystic Arte on the main arc's final boss, he declares it the last time he'll use said move. Yet the player can still use it in the Future Arc anyway after doing this, [[GameplayAndStoryIntegration causing Sophie to call Malik out on his lie]]. Malik'll humourously lie again to get her off his back.

* ''VideoGame/TheStanleyParable'' not only demonstrates this trope but also invokes it masterfully. Some of the endings can only be gotten through creativity on the player's part: [[spoiler: The Narrator lampshades what initially appears to be a GameBreakingBug as intentional, and some endings are non-intuitive--backing out of the boss's office while the doors close and heading all the way back to the start or actually playing the Narrator's GameWithinAGame for four hours as he suggests.]]

->(Use "Pick Up" key on Naranja)\\
'''Manny''': No. No more [[DoubleEntendre picking up sailors]] for me.
-->-- ''VideoGame/GrimFandango''

* ''Franchise/TheLegendOfZelda''

** Using the Stone Mask in ''VideoGame/TheLegendOfZeldaMajorasMask'' makes it so enemies don't notice you. It works on the majority of the Pirates, but the few that it doesn't work on have unique dialogue if you're still wearing it when you encounter them.
--> '''Pirate Miniboss:''' That mask won't work on the likes of me.
** There's also a minigame operator who will tell you how to get a Piece of Heart while not seeing you and thinking out loud if you wear the stone mask. All the other masks get "you sure have a lot of fun/nice/etc. masks!" And dialog for trying the Song of Healing on Sharp, and Skull Keeta's mask on the king of Ikana.

* The ''VideoGame/QuestForGlory'' series had a ton of these, especially amusing for players who think of particularly creative ways to get themselves killed. If you play as a thief, you start out with a lock pick in your inventory. If you type "pick nose", the hero will stick the lock pick up his nose and die, and you will get a game over. However, if your lock-picking skill is high enough, you will get a message that says, "Success! Your nose is now open!". Later games have the game reply "Success!" with the same sound effect the player hears when picking a lock. ''This also increases your lock picking skill''.
** The games also provided a ''lot'' of random, snarky descriptions for mundane objects that the player could examine.
*** While ''VideoGame/QuestForGloryIV'' was an ObviousBeta on the programming side, the writing department was clearly not slouching. Among other things, every single item in the game has its own message when you try to use it on yourself instead of a generic "that does not work" message. For example, trying to use a wooden stake meant for vampire slaying on yourself will cause the narrator to berate you for mixing up "stake" and "steak".
** If you type "put down lamp" instead of "use lamp" in ''VideoGame/QuestForGloryII'', it uses the colloquial meaning of "put down" and shows your character insulting the lamp before placing it on the ground.
*** The variation "drop lamp" will result in you breaking up with the lamp before you place it on the ground. You heartbreaker, you.
** True of any Sierra adventure game in the TextParser era. [[http://www.youtube.com/watch?v=xXFiT5JG-n4 For example.]]
** Even their later point & click adventures have this aspect. ''VideoGame/KingsQuestVI'' has Alexander BreakingTheFourthWall to yell at the player if they made him fall repeatedly during one sequence (if he wasn't killed by said fall).
* In the ''[[VideoGame/TheHitchhikersGuideToTheGalaxy Hitchiker's Guide To The Galaxy]]'' text adventure, it is necessary to the plot at one point to "enjoy [[spoiler:Vogon poetry]]". Earlier, you can "enjoy mud" (it's nice and squishy!), but if you try enjoying Ford, you are sternly told that this isn't ''that'' type of game. Additional fun can be had by inputting random words into the Guide -- it has entries on some very unlikely things.
** Often the game will refer you to a footnote (Like SEE FOOTNOTE 9), and when you type "footnote 9" it tells you something. If you keep on going through the footnotes (Trying footnote 10, 11, 12, etc) eventually you get a string of "There is no footnote (number)", until you finally get "It's fun reading all the footnotes, isn't it?"

* ''VideoGame/{{Zork}}'' responds to commands such as "win" and "die", and characters react to the phrase "Hello, Sailor".
** In ''Zork II'', at one point you come across a room containing naught but a giant bucket. If you should type "kick bucket" while trying to [[YouCantGetYeFlask Get Ye Flask]], the parser [[LiteralGenie helpfully replies]], "Kick the bucket? OK, if you insist. *** You have died ***"

* ''VideoGame/PeasantsQuest'' is chock full of jokes, {{Shout Out}}s, and responses to commands you weren't expecting. [[http://hrwiki.org/wiki/Peasant%27s_Quest_Responses#Unproductive_Responses See here]].

** This is fairly common in "one-room" Interactive Fiction stories. When the author only has to focus on a single player location and the items within, more effort gets to go to verbose item descriptions, verb creation, and clever responses to unique entries.
* ''VideoGame/GrimFandango'', being a [=LucasArts=] game, contains several of these. For example, trying to "pick up" sailor Naranja causes Manny to comment he [[DoubleEntendre "doesn't pick up sailors anymore"]], and this extends to numerous combinations:
-->("Use" torn stockings on Manny)\\
'''Manny''': I would never wear these. ''[[ComicallyMissingThePoint There's a hole in them.]]''
** Also applies to the trail of clues in Year 2, which culminates in a SolveTheSoupCans puzzle involving slip of paper which only reads "No. 36 - The Rusty Anchor". Whilst it's a pain to solve the first time, it comes with the bonus that a TalkToEveryone approach yields several unique responses depending on who you show it to; this even includes one that [[LampshadeHanging lampshades]] said responses:

* In ''VideoGame/MetroidZeroMission'', steps are taken to make sure the player can continue ahead even with ridiculously complex SequenceBreaking. If the player gets Screw Attack early, the Ripper that must be frozen to stand on it during the Kiri Guru boss fight cannot be killed by it unlike other Rippers. Managing a perfect stealth run through the Pirate Mothership will play a unique background soundtrack: the Wrecked Ship theme from ''VideoGame/SuperMetroid''. And it's even possible to beat the game with only 15% (as low at 8%) of all the items, with hidden routes to allow you to proceed forward.

* In the final sequence of ''VideoGame/DayOfTheTentacle'', you can attempt to go up to the attic and close the door, but Bernard will say that Purple Tentacle might lock it and trap them up there. There is no reason to go up there in the first place, so it's surprising that there's a specific line to deal with such a situation.
* In ''VideoGame/BenJordanParanormalInvestigator'', using the "Touch" icon everywhere will, in the final case, sometimes bring up a message chastizing you for acting like Hercrabbiness, who enjoyed using it on everything and everyone she could try. Use it on Ben, and he gussies himself up. And if you use it on a priest, you get a message saying [[RefugeInAudacity "Shouldn't that be the other way around?"]] rather than the standard message.
** At one point in case 5, the player will have a pufferfish that has not been prepared properly (read: Poisonous) in their inventory. Sure enough, there is an actual response to the player telling Ben to ''eat'' the poisonous pufferfish.

* In ''VideoGame/SuperSmashBros Melee'', each player is awarded bonuses after a match based on his or her performance. These bonuses range from easy (Coward: frequently run away from opponents) to extremely challenging (Switzerland: never attack, never take damage) to why-would-we-even-do-that baffling (Button Holder: hold down one of the attack buttons for the entire match). In short, no matter how you play the game, you'll be recognized for it. If you're trying to get the Diskun trophy, you're gonna have to to get every single one of these bonuses; in other words, you'll have to think of everything that the developers have thought of.
** Smash Bros 4 has one of the stages being the [[CoolTrain Spirit Train]] from ''VideoGame/TheLegendOfZeldaSpiritTracks'', with Link operating it. But if either Link or Toon Link is selected to fight, then Alfonzo will be driving the train.
* In a [[BlackComedy spitefully amusing]] example, calling Aerith against an AI Sephiroth in ''Duodecim VideoGame/DissidiaFinalFantasy'' will have Sephiroth's AI do whatever it takes to hit Aerith with [[DeathFromAbove Hell's Gate]], the [[ItWasHisSled same move he killed her with in]] ''VideoGame/FinalFantasyVII''.
* In ''VideoGame/Persona4ArenaUltimax'''s Golden Arena Mode, if you fight the [[EnemyWithout Shadow]] version of the character you're playing as or vice versa, the music for the fight will be 'I'll Face Myself' from ''VideoGame/{{Persona 4}}''.

* ''VideoGame/MortalKombatX'' features unique pre-fight banter for every combination of Kombatants. In addition, Erron Black's [[LimitBreak X-Ray Attack]] has him firing a MarkedBullet, with the name of his opponent etched into it. There's one for every Kombatant, including [[MirrorMatch himself]].

* In the ''VideoGame/{{Borderlands}}'' series, you have a limited amount of inventory space to pick up the guns/mods/etc. that enemies drop. If an NPC attempts to give you a quest-related item or a quest reward when your inventory is full, you still get the item anyway, with the inventory going over its maximum limit.
* ''TheNamelessMod'' has this all over the place, mostly because as a mod for a [[VideoGame/DeusEx nearly 9 year old game]], they know all the exploits in the engine. For example: climbing over a fence before you can unlock it will result in an NPC on the other side asking how you got there, and listing some of the possible methods, such as grenade climbing (sticking a grenade to the wall, jumping on it, sticking another to the wall, jumping, removing the first, and repeating).

* ''VideoGame/TowerOfGuns'', a rogue-like first-person shooter, apart from randomized ''everything'' (including plot), features an example in the ''Battlements'' stage: if you are smart enough to climb out of the level main area and [[spoiler:jump off the Tower]] while possessing the [[spoiler:Long Fall perk]], you find yourself in small secret stage with developer Joe pretends to be surprised with your actions and warns you that levelling and player stats may behave oddly. After that, you have to [[spoiler:start from the very first level]].

* ''Franchise/{{Halo}}'' is known for having a surprisingly robust physics calculation engine, especially in ''VideoGame/{{Halo 3}}'' and ''VideoGame/HaloReach''. To say that everything is taken into account is almost not an exaggeration. Bungie made it so that the later games in the series will account for such vanishingly small possibilites such as shooting rockets ''through'' the open sides of a gunship while missing all its occupants and leaving it unharmed, a sniper rifle round hitting several valid hard surfaces in a row at the right angles and ricocheting off each one (resulting in some truly absurd kills), and an enemy standing in front of a Spartan when their NighInvulnerability upgrade is activated getting killed because ''they were punched in the face when the activation animation played.'' That's attention to detail.

* In ''CarmenSandiego's Great Chase Through Time'', you can actually use all sorts of items around the world and get a comment, normally something along the lines of "ICantUseTheseItems", or a person (such as your good guide) explaining what it is. On top of that, it's actually possible to try and use the time cuffs on people, usually for a funny comment, such as a Roman saying "I'm cleaning up - but not through thievery!" or Ann Tikwitee saying "Uh gee, I don't think there's a thief in my pocket, do you?"
** You can also get some rather humorous responses using random items around:
*** Use torch on Queen Hatshepshut. "CAREFUL! Or you'll singe my false beard!"
*** Use battle axe on Rock Solid. "OUCH! Don't cut me down to size!"

* In the video game version of ''Series/WhoWantsToBeAMillionaire'', entering in one of the names of an actual million-dollar winner (such as John Carpenter or Dan Blonsky) will cause Regis to mock you and [[FailOSuckyname enter in a more disparaging name such as "Phony Cheats"]]. Regis also has his own specific dialogue if you try to enter ''his'' name.

* ''VideoGame/WorldOfWarcraft'': back in the days before the Cataclysm expansion pack was released, if you went through a demon-infested gorge, jumping in exactly the right places and using a since-patched glitch known as wall-walking (which was literally jumping up a normally untraversable wall or terrain in a very precise manner to trick the game into thinking you've grabbed a foothold), you could enter the then-uncompleted Mount Hyjal. When you got there, you found a zone that was actually fairly fleshed out, including the skeleton of Archimonde. The actual note that merits this entry: construction signs telling you you weren't supposed to be here and better get out, and you would receive a debuff called "No Man's Land" that instantly teleported you out even if you somehow manage to enter it. There were even rumors that you would be ''automatically reported'' to a GM upon receiving the debuff, as the player would have had to deliberately and willingly break the rules of the game by using an exploit several times to get there.

*** Most city guards will react to emotes, /rude them, they respond in kind, salute them, they salute back, etc. etc. Also, flex your muscles at them. [[SugarWiki/FunnyMoments They are not impressed]].

*** And, being Chen Stormstout's niece, she supposedly is [[InformedAbility an adept brawler]] on top of that. However, when inquiring why she doesn't help you fighting off critters, she reminds you that you shouldn't need the help of a little girl to do that. (That said she does get to show off her skills in HerosOfTheStorm)

** Normally if you try to do something in a druid or shaman shapeshift form that you need to be in a humanoid form to do, the error message will just say "you can't do that while shapeshifted." Sometimes, however, it will instead tell you "that requires opposable thumbs."

* A magic shop keeper in ''VideoGame/RuneScape'' gives out free Mind Runes and Air Runes every five minutes or so. Trying to sell the freebies back to him will net you a sarcastic comment.

** In the Pirate's Treasure quest, the player is only supposed to smuggle the Karamjan rum via the banana crates. All other methods (teleportation, etc.) will cause the player to lose the rum.
** No longer true, as of 2013 there's currently several methods in the game to smuggle the Rum, most of which are detailed [[http://runescape.wikia.com/wiki/Karamjan_rum here]]
** In a certain part of the Tai Bwo Wannai Trio quest, the player must mix a banana with a bottle of the aforementioned rum. For this, the player is supposed to slice the banana with a knife before adding it in. Not doing so has the player stuff the banana in the neck of the bottle, unable to get it out, leaving them with a useless item.
* ''VideoGame/KingdomOfLoathing'' has special messages for certain things that can only be obtained through exploits, such as finding plurals for unique items (Ex. The plural for Emblem of Ak'gyxoth, an item rewarded to the very first person who summoned Ak'gyxoth, is Emblems of Ak'gyxoth, you dirty exploiter), or trying to do unclickable actions via http links (Ex. Attempting to use a Comfy Sofa without owning one will result you in falling to the floor and taking damage). Hot stuffing, an item that can only be crafted by using a Javascript command, is listed in the Discoveries section under the "Dirty Exploits" category.

** The Zombie Master class's playthrough focuses on attacking enemies and eating their brains. There is exactly one regular monster that will never drop a brain -- a mummy. [[FridgeBrilliance Because mummies had all of their organs removed during preparation]]!

[[folder:Multiple]]
* Many games have intentional safeguards to prevent the game from crashing or entering the territory computer programmers euphemistically refer to as "suboptimal performance." In this case, it's not really "thinking of everything," but just good programming technique -- assume "everything" is possible, and plan accordingly. A good example is the Chris Houlihan room in ''VideoGame/TheLegendOfZeldaALinkToThePast'', which is loaded whenever the game can't find the proper room data for where Link is supposed to be. ''VideoGame/FinalFantasyVI'' has tons of such "default" data, such as default monster reward data (which, if you're curious, is a Thunder Blade or a Jewel Ring, with no EXP or Magic points).
[[/folder]]

* At one point in ''VideoGame/{{Psychonauts}}'', you have to go into the minds of a few people to assemble a disguise to trick the warden. A lazy or creative player might think that just jumping into the warden's mind would be quicker. The game will let you try it, but all you'll get is an amusing note explaining that the warden is protected against psychic interference. Similarly, if you try to jump into any of your fellow campers' heads, you'll get a notice saying that the mind-jumping-device won't work on minors.
** In the normal course of gameplay, after saving the turtle Mr. Pokeylope, you carry him for about '''30 seconds''' before losing him forever. If you decide to take Mr. Pokeylope to camp after saving him, every camper reacts to him in different ways, mostly involving how adorable he is. In fact, almost every NPC in the game reacts differently to every single power-up you use on them, and every item you could possibly show them. One particularly amusing example: Using the "Rose" item from Black Velvetopia on the dog painters will make them tell you to "[[InterspeciesRomance Go find someone your own species.]]"
*** The PC version on Steam even made showing him to ''all'' the campers unlock an achievement.

*** Also leads to a minor heartwarming moment, [[spoiler: as Agent Nein sees Raz as a younger version of himself. Although, given the similarity to Raz at the end, it could be Raz as a Psychonaut.]]
*** You can even use it on a ''keypad''. [[spoiler:It sees Raz as a giant finger.]]
** In the Milkman Conspiracy, Clairvoyance works differently. Every G-Man and hidden camera sees you the same way, which changes based on which "disguise" item you're holding - ''except'' for the hidden cameras in the pink flamingo lawn ornaments, which are the ''only'' entities in the game for which Clairvoyance ''doesn't'' change Raz's appearance - rather than a 2D image, they just see his 3D model.

* In ''VideoGame/YoshisIsland'', it turns out Bumpties can steal Baby Mario if he's knocked off Yoshi's back next to one. The twist? This very, very rarely comes up in the game by default, so they programmed in behavior for an unlikely situation that's only likely through going out of your way to take damage and that's so obscure even Mario Wiki didn't know about it until recently... From [[http://nintendo3dsdaily.com/nintendoarticles/yoshis-island-tour-part-17-the-best-and-the-worst/ here]].

* ''VideoGame/Rockman4MinusInfinity'', being the [[DoingItForTheArt labor of love]] that it is, has a number of these moments:
** The credits (which feature ''Franchise/FireEmblem''-like stats for the Robot Masters) also record the weapon you killed them with.
** Mega Man has a unique sprite for standing on ledges.
** In the fight with Pharaoh Man, he starts destroying the pyramid you're in. If you revisit the stage after beating him, the damage is still there.
** All the Robot Masters change their patterns to avoid Rush Cannon if you fire it. Some actually find ways to [[HoistByTheirOwnPetard kill you with it.]]

* ''VideoGame/CastlevaniaDawnOfSorrow'' has a boss named Dmitrii, who is a DittoFighter - any attack Soma hits him with, he'll use in turn (though no matter the level of Soma's attack, Dmitrii always copies it at Level One). This includes nearly every attack in the game, including ones you can only possibly have in this fight on a NewGamePlus. He can even copy Hell Fire, the attack you can only learn by completing the game on Hard. What's more, he's also able to copy the attacks used by the characters in Julius Mode.

** Jet-Vac uses a [[WeaponsThatSuck vacuum device]] to attack and fly. His flight capabilties are limited and indicated by a gage based upon how much compressed air he has in his tanks. If you deplete some of it, and activate the secondary attack (Which sucks enemies towards you), he refills it.
** Give Hot Dog a hat with a bone in it and he will actually have it in his mouth instead.
** In ''Swap Force'', Wash Buckler and Rattle Shake are already wearing hats. Put another hat on them, and they will replace their default hat with it.
** The first BossBattle in Swap Force is a BullfightBoss where you have to trick the boss into running into the wall at you and crash. To do this, the player must have their Skylander in the boss's sights, and the boss will follow you if you walk around. If you are using Stealth Elf or Stink Bomb, two Skylanders who can turn invisible, the boss will not actually follow you.
** In ''Spyro's Adventure'', there are crystal walls that are normally invulnerable and require bombs to destroy... unless you are using Prism Break, whose expertise is altering crystals.
** Magna Charge's upgrades actually replaces his default weapon - and his idle animation actually changes to reflect this.
** You can actually give nicknames to both a Swap Force member's top half and bottom half.

* In ''VideoGame/DwarfFortress'', if you piss off the humans enough to start a war after letting their guild representatives wander through your fortress, they avoid any traps said representatives have seen.
** There was a report on the forums a while back of a dwarf that got disemboweled and somehow managed to recover. Everywhere he walked, he'd trail a little "[[color:red:~~]]". ASCII {{Gorn}} strikes again.

** This extends to the developer himself! Toady One has made arrangements for the code to be open sourced [[AuthorExistenceFailure if the worst happens.]]

** For example, arrow traps can be triggered by ''any'' kind of movement, which means a careful spelunker can use them to kill monsters for him or drop rocks to trigger them safely from above. He can sometimes retrieve the arrow to use as a weapon.

** Said falling platforms can be used to squish enemies, as can movable stone blocks.

** In the unlikely circumstance that two trees in the Lush area are generated side-by-side at the same height, their tops will form one long canopy.
** It is possible to kill stunned enemies by throwing them onto spike pits.
** If you pick up an item in the shop but figure the price tag is too steep, then you can always blow up the shop, right? If you touch the merchandise, walk out, and attempt the Ballistic Discount technique above, then you will be shot the moment you light the bomb instead of when you throw it into the shop. The Shopkeepers are on to us! Run!

** In the HD version, you can ''sacrifice yourself'' to Kali [[http://www.youtube.com/watch?v=d7ikKREYSIc like so]].
* In [[HyperRogue HyperRogue]], there are a lot of unusual interactions from bringing monsters to regions where they wouldn't normally appear.

** The Dark Elf's cave in ''VideoGame/FinalFantasyIV'' is surrounded with a strong magnetic aura that prevents any metallic equipment from being used, since the Dark Elf is weak against metallic weapons. Ordinarily, if any of your characters is using any metal equipment in this dungeon, they'll be afflicted with a permanent Paralyze status. However, you can use your newly acquired GlobalAirship to fly to a town that sells silver equipment before going to the dungeon. Since silver is a non-ferrous metal, it's completely unaffected by magnetism, so you can use it in the Dark Elf's cave without penalty.
** When you reach Ramuh and Esper!Terra in ''VideoGame/FinalFantasyVI'', the dialogue for your party members is non-specific, each party member saying the same thing, no matter who's in what position. But if you take a party that consists of just WildChild Gau to this encounter, the dialogue changes to properly reflect his HulkSpeak.
** The PostFinalBoss of ''VideoGame/FinalFantasyVII'' is supposed to be finished off by unleashing Cloud's LimitBreak. But, if you just stand there and do nothing, Sephiroth will eventually attack Cloud. This attack is gravity-based, so it can't kill Cloud, no matter what his HP is. Even then, Cloud will automatically counter-attack, winning the fight anyways.
*** Searching the game's code shows just how much the dev team thought of for this battle, too. Attack Sephiroth and do no damage? Attempt an attack and miss? Attack and ''heal'' him? He'll still go down.
** In ''VideoGame/FinalFantasyIX'', Quina is an OptionalPartyMember during the first disc. If you recruit him/her, the game will acknowledge that s/he is with the party during Disc 2, and s/he is PutOnABus via a RunningGag where Quina is almost always the one left behind. Returning to Qu Marsh on Disc 2 will have Quina greeting Zidane&Co and Zidane asking how s/he escaped Clerya. If the player did not recruit Quina in Disc 1, then the scene that plays when they just meet Quina for the first time plays.
*** The game has a heiharchy for who "leads" the party when [[CantDropTheHero Zidane]] is not present. This normally applies to the Desert Palace, but if Zidane is removed from the party for the final battle, the game will designate a "leader" who gives the WorldOfCardboardSpeech to the FinalBoss. [[note]]The hierarchy is as follows: Eiko, Steiner, Vivi, Freya. As it's impossible to have less than four party members, it is unknown who takes priority after Freya[[/note]]

* In ''VideoGame/GoldenSun: The Lost Age'', after [[spoiler:lighting the Mars Lighthouse]], the player controls Felix only, which means that the psynergy 'Mind Read' shouldn't be usable. With the help of [=ROMs=] and cheat codes, it can be given to Felix. Using Felix's newfound ability in [[spoiler:Prox]] results in new information in the mind reading dialogue boxes the developers put Mind Read text in normally non-mindreadable characters. Not just text, which would just be there to prevent the game crashing over an impossible action, but ''plot hooks''.

** More recently, it's been discovered that you can glitch-exploit Retreat to skip the part of the game where Mia joins the party. In doing so, you also skip the only part of the game where Mia's unique Ply power is required for puzzles. A boss later in the game provides an artifact that lets other characters use Frost, so you can solve Frost puzzles without her, keeping the game from being UnwinnableByMistake without her.

** Most players are unaware that Crossbone Isle is actually accessible earlier in the game. During the boat ride across the Karagol Sea from Kalay to Tolbi, if you assign strong rowers on the left and weak rowers on the right, the ship will veer off-course and land at Crossbone Isle. You can explore the dungeon, but it is impossible to complete since, at that point in the game, you lack the necessary utility Psynergies required to advance past the fourth level.

*** When in speaking roles, Djinn also tend to have increasingly-amusing responses to being continually denied, and a character in the first game will complain if you change your mind repeatedly in one cutscene and cause the conversation to loop.
** In ''The Lost Age'' and ''Dark Dawn'', certain areas have one route that can be navigated by a team of Earth, Fire, and Wind Adepts like the heroes, and another route that can be navigated by a single Water Adept, [[FridgeBrilliance like the ones that according to the storyline traveled through that area before your group did]].

** Similarly, the Wii version also possesses animations for scoring an own goal (basically almost impossible to do by accident).
** You can hold about a hundred different players in each iteration of the games (except the first one). A devious mind would think of recruiting all the goalkeepers in the game in order to have an easy shot all the time. Starting from the second game onward, you only own a "copy" of the player, meaning that you can have mirror matches but the opponent will still retain their goalkeeper.
** In all games, all story related opponents have their own little voice taunt whenever they score (even such weaklings as the Kid's Football Club). Turned UpToEleven in the Wii releases of the game: every player who's about to use a [[SpecialAttack hissatsu technique]] will use an individual grant to signal their intentions. Some even have alternate ones for very specific situations, such as Hiroto using a shoot hissatsu when Endou is the opposite team's goalkeeper. Not only does every character has their own voice lines for scoring (even those who will most likely never play offense, like the keepers), but also voice lines for shooting, goalkeeping, defending AND dribbling, even if they don't possess any hissatsu in that particular skill. Too bad the same can't be said for the announcer...
** In ''Inazuma Eleven GO 2: Chrono Stone'', you can select any character in your roster and press Y to view them up close, where you can rotate them and press A to cycle through various poses. A couple characters have several extra poses (often things they did frequently in cutscenes) which appear if you cycle through all the standard poses:
*** The EndgamePlus content allows you to recruit Okita Souji (yes, ''[[http://en.wikipedia.org/wiki/Okita_Souji the]]'' Okita Souji). He has two additional poses, coughing and wheezing from his tuberculosis.
*** Alpha, Beta, and Gamma have poses pressing their headsets.
*** Kinako has a BirdRun pose and her signature "Cheese!" pose.
*** Tove has a couple sleepy poses and his signature dance.

** Similarly, it is possible to actually leave a few worlds before beating the bosses there - if you return, they get stronger, and any scenes with Maleficent will not play.

** In ''VideoGame/KingdomHeartsII'', all sound when entering the Timeless River changes to mono to keep the feel of a 1940s cartoon.

* In ''VideoGame/TalesOfGraces'', most characters have certain moves and such that they only get later on and have quotes for in the Future arc, but have different phrases for when they're used in the game's main storyline. For example, Asbel's SuperMode and its resultant LimitBreak move are only available in the game's future arc and he mentions teaming up with [[spoiler:Lambda]] during said LimitBreak. If the player, on NewGamePlus, carries the titles that unlock said super mode and Limit break to the game's main arc, Asbel's phrase will be different.

** The Ethereal Potion does not allow the player to walk through certain types of walls. Certain dungeons are made largely of the impenetrable walls to prevent the player from just sliding through with an Ethereal Potion.

** "Falling Wall" scrolls will knock down some walls, but not all of them. Among the types that it won't knock down are the ones with shapes on them, so you can't use a Falling Wall scroll to knock down a Heart wall if you don't have the Heart key.
* In ''Videogame/TheLogomancer'', the steps of many quests can be done out of "normal" order, such as solving a problem before finding the quest giver, but everything will work out fine and you'll just get some Easter Egg dialogue for your trouble.

* At the end of Battle 5 of ''StarWarsTieFighter'' Admiral Harkov has three ships in his fleet, which get incrementally destroyed over the course of the battle. Two of the ships can be destroyed by you and will reappear in later levels. However Harkov's command ship (and later Zaarin's) cannot be destroyed and will hyperspace out of the level with 1 hull point no matter what you do.
* ''VideoGame/FreeSpace'' came bundled with FRED ([=FReespace=] [=EDitor=]), the same development tool the designers used to create the main game's missions. They included a rather amusing response to one attempt at crashing the program. FRED has an autonaming feature: before the user gives a ship a unique name, it is given a generic name based on its class and how many ships have been placed already. It was discovered that attempting to trick FRED's autonamer by renaming a ship to the next ship name in line (for instance, naming a ship "Ulysses 2" and then placing a second Ulysses) would result in the new ship being autonamed "URA Moron 1". For those interested, renaming a ship the next ship in line ''and'' renaming a ship "URA Moron 1" results in the next ship being "URA Moron 2", and so on.

*** And yes, the only way to do that is by cheating. The developers of the mission went so far as to design a custom, extremely difficult AI setting for the reinforcement fighters tested against some of the best players in the fanbase, so don't think you're going to disable some guns and be able to pull off a win.

* Each expansion in ''The Sims 2'' included big gameplay elements that would have to be accounted for in future expansions, leading to extra features that you would never see if you only had one or two installed.
** In University, the college neighborhood has certain restrictions due to time passing differently and students being in their own separate age group with its own game mechanics, which all later expansions had to take into consideration. Students also have teenage voices, meaning the voice actors would have to record lines for all the things adults can do but teenagers cannot.
** Nightlife introduced a new aspiration, (Pleasure), which would need to have wants and fears assigned to it in all later expansions.
** Open For Business allows players to run their own business, meaning all community lot items in future expansions (such as food stands and pet shops) would need to work when controlled by the player.
** Pets cheated a bit; cats and dogs aren't permitted at university, and they can't be taken on vacation. Still, though, they can interact with objects only included in previous and future expansions.
** Free Time's hobby system assigns an appropriate hobby to almost EVERY SINGLE OBJECT IN ALL EXPANSIONS.

* Many ''HarvestMoon'' games have events based on your friendship with certain people. Some of the events involve characters who are in the pool of potential {{Love Interest}}s; some of the events must be seen if you want to marry them, but some of them are optional. If you see these optional events after you've married them, the dialogue will often be slightly different -- in addition to calling you by your nickname, they'll say somewhat different things.

*** What's even more disturbing is that he will also pick up your ball if you leave it on the floor of your house or throw it in the pond in the basement. He breaks into your house to steal your stuff and give it back to you.

* ''TachyonTheFringe'' has a similar setup to ''Beyond Zork'', wherein using cheat codes will result in the main character making fun of you. The fact that the main character is voiced by ''Creator/BruceCampbell'' almost makes it worth cheating.

* ''X-Plane''. The simulator for which one of the version update notes mentions that, to increase performance, ''individual raindrops'' will only be simulated within a few metres of the plane. And which includes drivers for several actual plane dashboard and radar console hardware simulators..

* ''VideoGame/{{Hitman}} Blood Money'' anticipated for "Til Death Do Us Part" that people might disguise themselves as a [[http://www.youtube.com/watch?v=fAXPSR3hL1Q priest during a wedding]]. So naturally, there's a bonus cutscene where you can tie the knot for your target.

* In ''VideoGame/SplinterCellConviction'', the new, improved takedowns include slamming a hostage's head against the wall. If you do this in front of a light switch, [[http://www.youtube.com/watch?v=5D5Zmy2kkq8#t=44 the Player Character slams the hostage's face into it]]. This turns the lights off.
* In ''VideoGame/{{Dishonored}}'', the introductory level features a character whose portrait is being painted. Near said character is an item of small monetary value. Much later in the game, the painting is visible in a room; if the protagonist stole the item during the intro, it won't be visible in the painting either, and a character will complain about its absence.

** A lot of the more subtle game mechanics in the ''Franchise/{{Disgaea}}'' series seem to be built around this trope as well. Throwing enemies into your base panel, for example. (Save first.)
* [[http://serenesforest.net/fe9/npc.htm List of characters that can be hacked into]] ''[[VideoGame/FireEmblemTellius Fire Emblem: Path Of Radiance]]''. The fact that one of these characters shares a name with a character from ''[[VideoGame/FireEmblemTellius Radiant Dawn]]'' is probably just a coincidence, as the two have different classes. The fact that [[spoiler:Zelgius]] and the Black Knight have the exact same affinity, weapon ranks, and growth rate? Not so much. Yes, the Dev Team Thinks of Everything, including putting in spoilers for the sequel.

*** For that matter, in Path of Radiance, you get a lot of variance in scenes depending on whether or not certain characters died. (Even some ''Support Conversations'' change to reflect who's alive and who isn't, most notable being [[http://www.serenesforest.net/fe9/support/054.html Makalov and Astrid]])
*** If you [[LordBritishPostulate have Ike fight the Black Knight]] [[FinalBossPreview when he appears in Chapter 11 (he's unbeatable at this point)]] and Ike somehow survives, you get a few extra lines at the end of the chapter where Mist gives Ike an AngerBornOfWorry-fueled WhatTheHellHero.
** Similarly, ''[[VideoGame/FireEmblemTheSacredStones Sacred Stones]]'' has the image and stats for Nergal, the BigBad of the previous game. Even though they take place in completely different worlds.

** Also, in some ''FireEmblem'' titles, there are levels in which there is a door which opens automatically after a specific number of turns, usually by an NPC. Under normal circumstances at the points in the game which they occur, it is effectively impossible to get to the door before it automatically opens. However, if the player somehow manages to reach the door and open it themselves, an otherwise inaccessible cutscene is displayed to accommodate the situation. Chapter 16 in ''Rekka no Ken'' is an example of this.

*** Related: There is actually a bit of GameplayAndStoryIntegration around this subject, too. If you ''do'' play the prologue, and send a character to be KilledOffForReal, you can't use them. Later in the game, you are given one item called the Aum staff, that lets you resurrect one character. Since most players go for 100% survival, a lot of players' first instinct was to use it on the sacrifice, but it's not an option. However, "New Mystery of the Emblem" brings about a very clever explanation: [[spoiler:Frey was indeed the canon sacrifice; however, he is alive and well in New Mystery. Supports with the player reveal that he was the sacrifice, but instead of being killed, he was beaten up and left for dead, but was rescued by some civilians, and survived with a scar and memory loss. So in summary, you can't use the Aum staff on the Sacrifice, because they ''never actually died!'']]
** There have been a few occasions in which a boss who [[LordBritishPostulate you are not supposed to beat]] actually has dialogue or a situation on what happens if you ''do'' manage to beat them.

**** Which is a piece of cake with Larcei and 100* Hero Sword: http://youtu.be/OKCp-7at92s
*** You are told not to kill Fargus in ''Rekka no Ken''. However, you actually ''can'' attack him (Which isn't recommended, seeing how powerful he is) and the game takes into consideration what happens if you ''do'' kill him -- you get a GameOver.
**** Attacking him nets you a game over when the enemy's turn starts, even if he survives.

** In ''VideoGame/FireEmblemAwakening'', Chrom and Lucina's Falcions are both usable by Spotpass and DLC Marth. It ''was'' originally ''his'' sword, after all.
*** Regarding Chrom, his promoted class' battle model uses the Fire Emblem as a shield. The Fire Emblem is first given to him in Chapter 7, but if you manage to do a ton of LevelGrinding and get Chrom promoted before then, the shield ''won't'' appear on his model until he recieves it in the story. And when the shield is taken in a story event later, it will also dissapear from his model.

* The ''VideoGame/SuperRobotWars OG'' games have sets of dialog for any character piloting any mech (except in cases where characters have their own specific, exclusive one), occasionally with some [[http://www.youtube.com/watch?v=WWzDNAQSdsI humorous]] [[http://www.youtube.com/watch?v=J9VImGdjXj8 results]].
** Additionally, an early scenario in [=OG2=] has the player, with only four units, being ambushed by three boss units. However, with persistence, a [[strike:crazy]] player CAN beat them, resulting in a BreakingTheFourthWall moment and rewarding the player with various powerful items.

* ''{{Starcraft2}}'', in one of the Ultralisk advancament missions. You're rampaging through the city with an army of Ultralisks, and at some point you come across a lonely parked car close to a building, of no relevance whatsoever. If you destroy it its owner will come out of his home, yell at you for doing it right after he'd finished paying for it, and [[SuicidalOverconfidence open fire]].

* In ''VideoGame/DeadSpace2'', Isaac normally finishes off Tiedmann right before facing the FinalBoss by shooting him through the head with the javelin gun. But, it's also possible to fry him with the gun's secondary fire function. Missing with the shot or just not shooting at all makes Tiedmann fall over dead on his own.
* ''[[OperatorsSide Lifeline]]'', the game controlled almost entirely by voice commands, there are quite a few words in Rio's dictionary that you might be surprised by, especially if you didn't actually say them due to the prototypical nature of the game's main feature. Telling her to commit suicide, for example, elicits a response unique to the request. You could also say Rio's voice actor's name (the exact name depending on whether or not it's the Japanese version or the English version) when asked who your girlfriend is for a unique response. She also dislikes it if you swear.

* In ''VideoGame/CallOfCthulhuDarkCornersOfTheEarth'', seeing too much disturbing stuff at once will cause Jack to freak out in a number of different ways. One such way is that he'll start muttering to himself in a panic. What he mutters is in direct context to whatever he's seeing that scares him, be it a ghostly girl, a rotting corpse, or a giant monster made of brown acid.

* If you find a glitch and fall outside the boundaries of the level in ''SlenderTheArrival'' you die and text from Slenderman appears at the bottom of the screen saying "even a glitch in the game can't save you from me."

* ''Anime/MobileSuitGundam -- Encounters in Space'' has a truly staggering number of special voice clips for Versus Mode, dependent upon several factors including the characters' partners, their abilities, their mecha, their opponents (as well as ''their'' abilities and mecha.). For one particular example, putting [[Anime/MobileSuitGundam Amuro Ray]] in the [[Anime/MobileSuitGundam0080WarInThePocket Gundam NT-1]] will have him start the fight with "[[MemeticMutation This Alex]] [[CallForward isn't just]] [[CharsCounterattack for show!]]" This is also true for the game's Create-A-Characters, who are fully voiced. Making this more impressive is the fact that this is exclusive to Versus Mode, since a vast majority of the combinations involved can't happen at all in the standard story modes.

*** Having [[GundamSeed Kira Yamato]] pilot the InfinityPlusOneSword unit, Knight Gundam, will have him sometimes begin a mission saying that he can do some real good with his new sword, before shouting the Gundam's name.
* The first non-prologue area of ''MaxPayne2'' involves the investigation of a warehouse area. One of the private cleaners of the site insists on letting you in and showing you to the main storage area, at which point he and several of his underlings ambush you and the real violence begins. Unless, of course, [[NewGamePlus you already know what's going to happen.]] You can simply kill him upon your first encounter, causing the monologuing protagonist to say 'The perp's disguise didn't fool me, he was leading me into a trap' instead.
** All over the place, actually. Any stage that allows you to roam around in one way or another supplies you with many little sweets, some dialogue, and some actual animations:
*** Just for instance, in Payne's or Corcoran's apartment complexes [[spoiler:during their respective shootouts]], if you knock or try to open any other apartment doors that you aren't supposed to, people inside will call out to you things along the lines of ''"Get lost!"'', ''"The cops are on their way!"'', and ''"[[CoitusUninterruptus Ooooh, ooooh yeah!]]"'', thus averting the [[ConvenientlyEmptyBuilding mistake other games usually commit]].
*** Or the police station: There is, of course, a man making a statement on [[TheCoronerDothProtestTooMuch how his wife and her lover killed themselves in his house and THEN framed him for the murder]] or the stripper who receives threats from her [[SelfDeprecatingHumor video shooter-addicted]] boyfriend after she threw his TV out of the window.

* In ''RedDeadRedemption'', you can whistle to call your horse to you. If you do this while a dog is nearby, [[note]]there is usually one or two roaming around in the settlements[[/note]] it will follow you.
** You can also lasso deer, elk, goats, and rams, but you can't ride them.

** The trains will stop at a junction to wait for another to pass through before going themselves.
*** Speaking of trains, there is an achievement for [[ChainedToARailway dropping a hog-tied woman in the way of one]].
** John (and subsequently [[spoiler:Jack]]) has multiple unique battle taunts for each of the twenty (and completely optional) bounty targets.
*** [[spoiler:Jack]] also has a full set of dialog recorded for each Stranger mission if you wait until the endgame to complete them. The one exception to this is [[spoiler:I Know You]]. If you somehow manage to not do this mission before [[spoiler:John dies]], it won't count against getting a OneHundredPercentCompletion achievement/trophy.

** Averted, in the same sequence of letters there is also an [[http://en.wiktionary.org/wiki/shite E]]. Particularly vexing for British & Irish players if they get the response “That’s not English!”

** Another example is the extra dialogue you can get from randomly clicking on the same thing over and over again. A lot of the time, Sigma will try and hint at how useless it is to try and do something with the object, and will start to get angry if the player still clicks on the same object constantly.
--> [Examine once] Just a normal sofa.
--> [Examine twice] Just a normal sofa...
--> [Examine three times] Nothing odd about this sofa.
--> [Examine four times] Nope, still just a sofa...
--> [Examine five times] It's a sofa goddammit!
--> [Examine six times & Beyond] ''It's just a goddamn sofa!''

[[folder:Comic Books]]
* The sixth ''Comicbook/{{Noob}}'' comic has a scientist NonPlayerCharacter exposed to a conversation between players, hearing one of them say "NPC" and wondering what a "Enpeecee" is. Later, a random {{Mook}} encounters the main avatar (a priest) of a player after killing the secondary one (a warrior) and claims to not know what a "main avatar" is before saying "by the way, a priest is more fragile than a warrior".
[[/folder]]

** Not to mention, the Marauders took the time to rig the Marauder's Map to insult Snape should he read it. No, not anyone that read it without the password. Snape and ''only'' Snape. It finally pays off a good twenty years after they created the map.
* In the second ''Literature/{{Noob}}'' novel, the FictionalVideoGame's plot revolves around a whole continent waking up after being frozen in time for a few millenia. A NonPlayerCharacter awakes in a room full of other people who are still frozen and getting killed by players just because they noticed they could do it. The players get promptly killed by her. Later, another player ends up talking to her, and in the process realizing out loud that she's chronolgically older than his grandmother. The narration claims that the NonPlayerCharacter, physically a young woman, reacted to the word "Grandma" by refusing to speak with the player for a certain strech of time, despite having no in-game reason to do so.

* The pinball game ''Pinball/IndianaJonesThePinballAdventure'' features a sinkhole chute that is guarded by three targets. Normally the sinkhole is accessable only when the targets are struck and dropped out of play, revealing access. Because pinball games are physical, it is possible to slip by without striking the targets. The character Short Round will cry out, "you cheat, Dr. Jones!" and awards bonus points.
** There is also a bonus section where you are supposed to hit various targets to fight against a swordsman displayed on the screen. However, if you remember that the ball launcher is designed like a gun trigger, you can indeed [[CombatPragmatist follow in Dr. Jones' footsteps and just shoot him]].

* Williams Pinball machines were famous for their ability to detect when a physical part of the machine had failed and ''compensate for it'' by modifying the rules of the game. So if a sensor hadn't triggered for a while, the game would substitute another sensor along the same rail or shot. This was an incredibly useful feature for arcade owners, and the source of some annoyance that machines from other manufacturers didn't do this (this wasn't their fault, though - Williams patented it.)

* In ''Pinball/{{Funhouse}}'', Rudy's mouth is normally only a valid shot when it is locked open as he's asleep, but incidentally shooting the ball into his mouth while he's speaking causes him to swallow it and spit it out, scoring a "Rudy Gulp". In the similar table ''Road Show'', which featured two talking heads named Red and Ted, shooting the ball into Red's mouth while she's speaking will make her spit it out, shouting "You big cheeseburger!".

* On ''Pinball/StarTrekTheNextGeneration'', if you drained a ball or timed out during a Mission Mode without scoring points, you would get a minimum point bonus while hearing Data say, "Had you propelled the ball along the proper trajectory, you would have been rewarded." If you trigger both flippers at once midway through Data's line, you receive additional points as Captain Picard cuts him off with, "''THANK YOU,'' Mister Data."

** ''Pinball/JurassicPark'' even had a unique animation for it.
** In ''Pinball/TheAdventuresOfRockyAndBullwinkleAndFriends'', Mr. Peabody will compliment you for pulling off the Death Save.
--->'''Mr. Peabody:''' "Good work, Sherman!"

* When a Mac is broken/finds an error upon starting up, it beeps "S. O. S." in Morse code.
** A PowerPC-based Mac, on the other hand, plays the sound of a car crash, explosion or a scare cord
** Likewise, a legacy BIOS PC will beep out a string of codes, which can then be used for diagnosis by looking up a service guide. For example, one long beep followed by two short beeps indicate a damaged graphics card, one long beep followed by three short beeps indicate that one or more of the RAM modules have gone south.

* ''{{GURPS}}'' tends to evoke this, especially when reading the more specific supplements. The Space book, in particular, seems to cover EVERY possible trope related to space. The alien creation rules contain everything from trophic level to biological symmetry.
** The martial arts supplement gives '''''58''''' different real-world combat styles (not counting differentiation by era, and all forms of Kung-Fu are considered one style) plus another five they made up.
** Dungeon Fantasy 8: Treasure Tables gives listings for spices, toys, furniture, perfumes, paintings, and containers. It even gives guidelines based around culturally distinctive styles and additional trappings that the designer calculated to create several trillion variations. Dungeon Fantasy 2: Dungeons gives detailed rules regarding harvesting organs, teeth, and natural poisons of dead monsters and what bits of scrap taken from dungeon trappings will sell for back in town. Also, want to sell stories of your adventure to bards? There's rules for that as well. Other material involving the Dungeon Fantasy lines are templates for playing Justicars (city watchmen and kings' guardsmen), Sages, Ninjas, Innkeepers and [[ElementalPunch Mystic Knights]].
** Spaceships is probably the only place in an RPG book (outside of Traveller) that you can find relativistic equations. Fortunately, they're very much optional.
* Super-extra-lucky-rare tabletop version from ''VampireTheRequiem'': In the previous incarnation of the game, some Disciplines were notoriously easy to ignore. To hammer home that this iteration is more ruthless and harder to cheese, the developer's state that that using the Dominate Discipline always requires eye contact, and if a character were to try to ignore this rule by wearing sunglasses, said Ventrue player is free to laugh at the n00b's incompetence.

* Omega Supreme's toy in ''TransformersEnergon'' has three parts: A giant battleship, a huge crane, and a small robot which formed the head. When in combined mode, Omega Supreme's body (Made of the crane and the battleship) have a head of sorts that can be raised when the actual head unit isn't attached. Reason? To actually give the big guy a head if one loses the head robot.
** The same with ''Armada'' Sideways. His small "mini-con" partners turn into his head, one for his Autobot form and one for his Decepticon form. However, he has a pop-up head in his own color scheme just in case you lose both the mini-cons. Hasbro bigwig Aaron Archer is an AscendedFanboy who grew up with the old toys, which included the Headmasters (Transformers whose heads became small partners). He hated how if you lost the partner robot who became a head for one of the Headmasters, your robot just had to go headless (or share a head with another Headmaster). Worse were the later Powermaster figures, who couldn't even turn into robot mode at ''all'' without the partner robot acting as a 'key,' making it ''entirely'' useless if you lost (or stepped on) a partner figure [[note]]However, anything small enough to fit into the Powermaster socket and release the catch will work[[/note]]. When the Headmaster gimmick was dusted off for Armada and Energon, Archer saw to it that your Sideways or Omega Supreme will not be so unfortunate.
** Another Transformewrs example is the WarForCybertron Soundwave. While his robot mode looks substantially like his G1 counterpart, he turns into a car, not a boombox. However, in one of the ads for the game, they have Soundwave contort into a form that resembles his classic altmode... and there is evidence that you can do the same to his toy. Essentially, he has a second altmode as an undocumented feature.
* The robotic pet dinosaur, Pleo, is able to react to certain stimuli: Stroke its back and it wags its tail, scratch its chin and it purrs, hold it upside down or by its tail and it wails and cries. Shake it especially viciously by its tail, however, and it will actually sieze up and crash. It may just be hardware being jogged out of place (They are notoriously fragile), but if not, then it is literally programed too, when abused too much, die.

** People who typed "[=www.homestarrunner.com/sbemail100.html=]" into the search bar in an attempt to view the [[MilestoneCelebration 100th email]] before it was released would be instead greeted by a [[UnintentionalPeriodPiece (now very outdated)]] [[http://www.homestarrunner.com/sbemail100.html fake Internet Explorer error page]] where Strong Bad would appear and chastise the viewer for thinking they were clever. As a result, the url for the actual cartoon ended in "sbemailahundred" instead of "[=sbemail100=]."
*** A similar situation happened when people typed "[=http://www.homestarrunner.com/sbemail200.html=]", only this time it was a [[http://www.homestarrunner.com/sbemail200.html fake Firefox error page]] and the viewers were chastised by Strong Sad for trying to cut in front of his [[Recap/StrongBadEmailE188FanClub fan club]], who "started camping out weeks ago."
** In the actual 200th email, Homestar briefly mentions "Hremail 49" after reading the email Strong Bad was mistakenly sent. If you type in "[=http://www.homestarrunner.com/hremail49.html=]", you get a [[http://www.homestarrunner.com/hremail49.html very short cartoon]] in which Homestar mentions "Hremail 24." Typing in "[=http://www.homestarrunner.com/hremail24.html=]" takes you to a [[http://www.homestarrunner.com/hremail24.html red screen with text reading "BANNED FOR CONTENT".]]

* ''Webcomic/{{xkcd}}'' had an interesting April Fool's day in 2010, which can be found [[http://uni.xkcd.com/ here]].
** Especially funny if you type in a certain [[PrecisionFStrike four letter word]]. The response? [[spoiler:[[Fanfic/MyImmortal I have a headache.]]]]

*** Try [[SchmuckBait "sudo rm -rf /"]]. Similarly, ":(){ :|:& };:".
** "find" also works; the game asks you what you want to find, and suggests "kitten."
*** If you search for the afforementioned kitten, the console searches for the bizarre "game" Robot Finds Kitten.

** Hmm, I wonder if this has [[BrokenBase Vim or Emacs?]]
*** The response to trying to use nano is also quite amusing.

** The comic's 2012 April Fool's gimmick also qualifies. The strip posted that day, "Umwelt" [[note]]German for "environment"; it's an idea from semiotics. See the alt-text or ThatOtherWiki for more.[[/note]], came in [[http://www.reddit.com/r/xkcd/comments/rnpym/xkcd_umwelt_nonpermalink/c479h3s dozens of different variations]]; which one you see depends on your "perspective", i.e. location, browser, window size, etc. How extensively did Randall do this? There's a specific comic for ''Netscape Navigator''.
** xkcd's back at it again with [[http://xkcd.com/1110/ this]] strip. Click and drag and drag and drag and drag...
** According to the alt text on comic #1189, the US Census Bureau has defined the "US Census Bureau Solar System statistical boundary." If only this were actually true.

** Should you enter 42, it will tell you that it's not a prime number, but it is the Answer. If you enter 666, it'll tell you "No. And you're not the first person to ask. You little devils."
** Putting 69 makes the site go "You pervert."
* Pokécheck is a website that, among other uses, can check the legitimacy of any Pokémon uploaded to it. It takes ''everything'' into account when checking to see whether or not a Pokémon was likely edited or created using an external device, across three whole generations of games and events. (as Gen VI hasn't been implemented yet as of 5/5/14) Obscure spin-offs and [[LostForever limited-distribution events]]? Taken into account. Differences between Gen III to V ''data-structures'' like garbage bits in nicknames that are preserved in the transition between generations? Well documented. The fact that [[VideoGame/PokemonXDGaleOfDarkness XD]]'s Shadow Pokémon and certain Gen 5 legendaries cannot be shiny? Factored in perfectly. Unusual stat totals? It's got that covered. An obscure glitch that only affects five species? Of course. And if a Pokémon has a Trainer/Secret ID of 00666 or some equally unlikely number, it displays the message "Suspicious trainer [=IDs=]." The only way past it is to hack a Pokémon that is identical to one that could have been generated by a core series/Gamecube Pokémon title. [[FridgeBrilliance Which is the intention]].

* PNG files always begin with the following bytes (in hexadecimal): 89 50 4E 47 0D 0A 1A 0A. Seems random, but it's actually carefully constructed to prevent against as many potential problems as possible.
** 89 makes sure the file is interpreted with 8-bit data, and protects against file transfers that would convert it to 7-bit data.
** 50 4E 47 is the code for "PNG" so that image programs can identify the file. It's also human-readable, in case the file is opened in a text editor accidentally.
** 0D 0A is a [=CRLF=] (DOS-style line ending), and protects against file transfers that translate [=CRLFs=] to [=LFs=] (Unix-style line endings).
** 1A stops the file from being displayed as text under MS-DOS and similar systems.
** 0A is an [=LF=], and protects against file transfers that translate [=LFs=] to [=CRLFs=].
** In short, the PNG file format automatically protects against 90% of all possible file errors ''in the first eight bytes''.
** Similarly, the custom content in ''{{Spore}}'' are entirely in PNG format. Yes. A picture file. This allows saving pictures from the sporepedia website and moving into the creation folder and detected as Spore creation complete with information and tags, even when the computer is offline while playing Spore.
*** The PNG format specifies that you can have any "tag" you want in an image file. There are a number of required tags for image data, but PNG parsers are required to ignore tags they don't understand. So the ''Spore'' team could have made their own tag for the creature data, ''but they didn't''. Instead, they encoded the creature data in the alpha channel of pixels surrounding the creature's mugshot. Talk about taking the hard route.
*** Aversion: This trick was also used in The Sims 3 for iOS devices, which requires you to do a ''screenshot'' of the intended character at a designated export screen. Unfortunately, due to the differences imposed by the compatibility layer when running iPhone software on an iPad, the scheme fell flat on its face if exporting the character is attempted on an iPad.
* Detroit's Comerica Park, home of the Tigers, has a statue garden of their legendary players in the deep center field stands. One of them is memoralized with his glove up and open. The artist took the time to fill the interior of the glove with small nails, so that on the one-in-a-million chance that a home run is hit into the glove, the statue will "catch" it.

** Siri will recognise the question '[[Film/MontyPythonAndTheHolyGrail What is the airspeed of an unladen swallow?]]', expressly stating that you need to know this information as a digital assistant. [[spoiler: It's 25 miles per hour for a European swallow.]]
** Say "OK Google"[[note]]The command used on a modern Android device to summon the Google Now voice assistant[[/note]] and Siri will tell you that they "[[TakeThat think you've got the wrong assistant]]."
** And if you ever need to hide a body, Siri can teach you a few things.

** Several websites are now able to detect if the user has adblocking software installed. Some merely add a message intended to guilt trip you into turning it off while others are more intrusive (BlipTv for example makes you stare at a static message for ''90 seconds'' that [[SarcasmMode helpfully]] informs you that their ads only take up to 30).
*** Though that extra sixty seconds is a small price to pay when the alternative is unprotected browsing of a site known to have ads with particularly insidious malware embedded within them.
** Hulu just straight up refuses to play video if ads are blocked.

** Driving directions are given for journeys on different continents, including at necessary places "Sail across [insert body of water]".

** One caveat to how far the dev team managed to think ahead: It does '''not''' always factor in the presence of road construction. This shortcoming, shared by every [=GPS=] based navigation assistant, is one of the last plausible excuses for not embracing [=GPS=] aided navigation.
** They ask you to exercise caution if you ask for walking directions from [[WalkIntoMordor "The Shire" to "Mordor"]]. This particular EasterEgg [[NeverHeardThatOneBefore has gotten plenty of attention.]]
* Google's search function is amazing. You can do calculations, look up addresses, convert currency, and so on.
** Another interesting feature of Google's search function: looking up the word "zeitgeist" brings up a list of trending topics.

----

* ''TheDevTeamThinksOfEverything/Pokemon''

* ''Franchise/{{Pokemon}}'' offers plenty of these.
** General:
*** The move Ingrain recovers HP by digging roots into the ground for nutrients. As a result, not only is regular and forced switching for that Pokémon impossible, there is an element in place that negates immunity to Ground-type attacks from being a Flying-type or using Levitate, which affects exactly ''one'' Pokémon that naturally learns Ingrain (Carnivine).
*** And also Smeargle, who can use Baton Pass to give the Ingrain status to any other party member, including one with a natural immunity to Ground. This even puts the recipient in contact with Toxic Spikes, should they be there.
*** In every game where breeding is possible, putting two Pokémon of compatible Egg groups will create an egg containing the youngest form of the mother. If you breed a female Nidoran or an Illumise with a compatible Pokemon, said egg has a chance of hatching into their male counterparts--male Nidoran or Volbeat (which are counted as separate species in the Pokedex). Likewise, breeding the males with a Ditto (which can [[AnythingThatMoves breed with anything]][[note]]though it should be noted that whatever it breeds with has it as the primary influence for its stats, meaning that it's likely to be weaker than average[[/note]]) may also result in a female version.
*** In the games where you can grow and cultivate Berries, there is ''full'' data for the growth, water consumption, and yield rates of Berries that extends well beyond basic stats. It is designed such that the Mulches in later games actually affect Berry development by adding multipliers to these Berry stats. [[GuideDangIt Of course, these Berry stats are all hidden from normal player viewing.]]
*** In 3D battlers like PokemonStadium, all Pokémon have programmed animations for every single existing move, independent of said move being learnable under natural conditions or if a move not naturally learnable was hacked into a Pokémon. The N64 Stadium games had a feature in which should a certain Pokémon have a move it doesn't learn naturally in the games is highlighted in purple, whether said move is learned through cheat devices or a GEN 1 move that is possible to learn in GEN 2 (Like the Elemental Punches, if used in Stadium 1).
*** A Pokémon may return if it is released while knowing an HM. That's because [=HMs=] are required to progress in the games where they're used, and if someone released their last Pokémon capable of knowing that HM in an area where obtaining another one is not possible, it may render the player in an {{unwinnable}} situation.
*** Trading Pokemon with another player is the franchise's main draw ("Gotta Catch 'em All after all!), though some players will get the idea of trading a powerful high leveled legendary Pokemon to a friend (or another copy of a game they own) and have them steamroll the game with little effort. The dev team knew someone would try it and thus created a rule where traded Pokemon can only be controlled with certain gym badges and higher levels require more badges. Until you get those badges, trade Pokemon will rarely listen to you in battle and there's even lore behind this mechanic; Pokemon you catch instantly respect you because you proved your worth. Traded Pokemon already had a bond with its original trainer and will not give you the time of day until you can prove yourself by defeating the best of the best (gym leaders).
** Generation III (''[[VideoGame/PokemonRubyAndSapphire Ruby, Sapphire, Emerald]], [[VideoGame/PokemonRedAndBlue [=FireRed=], [=LeafGreen=]]]''):
*** The move Struggle had Contest stats, despite not being able to be used in Contests.
*** Official tournaments banned the use of Leftovers on Wobbuffet, and Wobbuffet alone. The reason for this is because if a Wobbuffet holding Leftovers went up against another Wobbuffet holding Leftovers, the match would keep going for eternity or until someone surrenders, as Struggle, the only move Wobbuffet can use that would deal damage to another Wobbuffet, would do less damage than Leftovers would heal. This rule was implemented the moment Generation III started, before any players had the chance to do it.
*** On Emerald Version, there's a location called Faraway Island that can only be reached via the event item Old Sea Chart. A plain island with the typical scenery, a readable sign on one side, and…ah, yes, ''Mew'' in the depths of it. Entering the depths, you find Mew fleeing into the tall grass. Little-known fact among players: the Cut move can be used to disperse tall grass. Try it there to find Mew quicker, and what happens? The screen flashes, Mew disappears, and a text box comes up saying "The feeling of being watched faded…"
** Generation IV (''[[VideoGame/PokemonDiamondAndPearl Diamond, Pearl, Platinum,]] [[VideoGame/PokemonGoldAndSilver [=HeartGold=], [=SoulSilver=]]]'')
*** Arceus, a Legendary Pokémon, can have any Pokémon type corresponding to what type Plate it has, and has a different color scheme for each Plate. The move Curse has the type ???, and is the only move with this type (until Generation V, when they've finally classified it as a Ghost-type move). If you hack the game so that Arceus has the same type as Curse, it has its own color scheme and sprites. Also, the event Spiky-Eared Pichu has a Shiny sprite.
*** The ''Diamond, Pearl, and Platinum'' games all have an NPC named Doctor Footprint, who gauges your Pokemon's feelings for you by their footprints. If you show him a Pokemon that doesn't have feet, he'll point that out (but give you a reading anyway).
*** In ''[[VideoGame/PokemonGoldAndSilver [=HeartGold=] and [=SoulSilver=]]]'', when the player first reaches Lake of Rage, if you fish with the Good Rod you will find only Magikarp. However, if you turn on the radio so that Team Rocket's evolution signal is playing, you will only catch Gyarados, albeit normal blue ones instead of red (unless you're lucky enough to beat the 8192 to 1 odds of finding one the normal way, that is).
*** In ''[=HeartGold=]'' and ''[=SoulSilver=]'', the player can do events based on the date (and sometimes the time) to reflect the original games' events. In order to prevent cheating by editing the date and time on the NintendoDS, as opposed to being "permanently" set on the GameBoy ([[VideoGame/PokemonRubyAndSapphire Advance]]) era (Gen III) games, the game will effectively ignore date changes until 24 hours or so have passed. For example, if you go to one of the Haircut Brothers, the right brother will show up on the day if you change it, but he'll either say "I have to close up for the day" or "I can only do one haircut a day". However, the game has a loophole so if the player sets the time so that it passes 12:00 AM, then the daily events are reset and can be played over again. Other events, like the Bug Catching Contest event, aren't affected, since there's no way to cheat if you change the date or time.
*** Also in ''Heart Gold'' and ''Soul Silver'', you can have one Pokemon walk around behind you, which you can talk to to get different reactions. The number of different reactions for different Pokemon in different situations is actually pretty impressive.
**** If you take a female Ampharos and talk to her while at the top of the Olivine lighthouse, the reactions of your pokemon suggest that your Ampharos developed a crush on the male one living there.
**** The only Sudowoodo in the game is pretending to be a tree. If you catch it, have it walk with you and talk to it while it's standing on the exact encounter spot, it will stand completely still - pretending to be a tree ''again''.
*** A new move called Gravity was introduced, which removes the Flying-type immunity to Ground and also prevents the use of moves that involve going into the air (such as Fly and Bounce). One such move to be prevented this way was Splash--a move that's ''already useless'' because it just causes the Pokemon to hop around. It's made even more useless by the Gravity dragging it down!
** Generation V ''([[VideoGame/PokemonBlackAndWhite Black, White,]] [[VideoGame/PokemonBlack2AndWhite2 Black 2, White 2]])'':
*** [=TMs=] have changed from being single-use items to have infinite uses, much like the [=HMs=]. However, when a Pokémon forgets a move in order to learn from a TM, the move learned with a TM takes on the current PP of the move replaced by the new move. This is to prevent repeated usage of [=TMs=] for the purpose of PP restoration.
*** At one point, the player has to capture Reshiram or Zekrom (depends on the version) to advance the game. However, if your party and PC are completely full -- which is ''very'' unlikely to happen by accident -- this becomes impossible, so the game lets you skip doing so and capture it at a different location after the end of the game.
*** N's a MotorMouth. If the player tries to outdo N by changing the settings to the highest possible text speed, N's speech will come out even ''faster'' than that speed.
*** Another ''Pokemon Black/White'' example. All Pokemon have two battle sprites: a front sprite that faces the enemy, and a back sprite that faces the player. These sprites are also used for the Pokemon musical. One Pokemon, Mawile, has its back turned to the enemy. So for the musical, in order to keep it from having its back turned on the audience, the programmers switched the back sprite and the front sprite.
*** Halfway through ''Black 2'' and ''White 2'', you inherit one of N's former companions. If you use it when you challenge N, he will recognize his Pokémon and praise you for raising it.
*** Also, when Memory Link is activated, you can catch all of the Pokémon N used in ''Black'' and ''White''. If you have any of the others, not just the Zorua, he'll remember those too when you meet him by Victory Road.
*** After [[spoiler:getting the DNA splicers and catching Reshiram/Zekrom, if you try to fuse them into Black or White Kyurem and then try to trade it off to an in-game NPC ([[OlympusMons not that you would anyways]]) the game says "That Pokémon cannot be traded." as it would result in the permanent loss of the DNA Splicers.]]
*** When transferring Pokémon from Generation IV to Generation V, there is a minigame in which the player must capture the Pokemon while they are jumping from bush to bush. Diglett and Dugtrio, who are permanently sticking their heads out of the ground, do not jump--they merely travel through the ground.
*** Similarly, in the Gen. 5 and 6 games, Pokémon will first give their cry and then fall to the ground/fly/levitate/[[WaterIsAir swim]] after being released from their Poke Balls. Diglett and Dugtrio, however, will automatically be in a hole in the ground after being released.
*** A few hold items were introduced in this generation and the following one that raise a stat if the Pokémon holding it is attacked by a move of a certain type. However, if the Pokémon has an Ability that renders it immune to that type and boosts a stat by itself, that Pokémon cannot use the item. This is to prevent potentially game-breaking strategies like Electivire holding a Cell Battery, who'd get two important stats raised if hit by an Electric attack without taking damage (Attack via the Cell Battery and Speed via its Ability, Motor Drive).
*** Feebas, in previous generations, evolves if its Beauty stat (normally reserved for Contests) is high enough. Because the Contests don't exist in Generation V and beyond, Feebas evolves by a different mechanic (trading while it holds a Prism Scale). However, if you managed to get a Feebas with maximum Beauty and transfer it all the way to Generations V and VI, it'll still evolve upon level-up.
*** Victini has a shiny sprite despite not being able to be encountered in a shiny form.
** Generation VI
*** Pokémon Amie takes note of actual Pokémon anatomy. You'll visibly injure yourself with Pokémon who have dangerous body parts, such as Pikachu's cheeks (where electricity is stored), Ferroseed's Iron Barbs (you'll prick/cut yourself on them), Slugma's ''entire body'' (you'll burn your hand!), and so forth. Some Pokémon even don't like you to touch them in such areas - Roserade doesn't want you to handle its rosehead hands (where it stores its poisons), and an Espurr you have formed a bond with will not like you to touch its ears (which are helping it restrain its exceptionally strong psychic powers by covering auxiliary neural tissue used for its psionics); likewise, a Honedge that likes you will shy away from letting you touch its tassel (Which it uses to punish people who dare to use it as a weapon by draining them of their energy!)[[note]]However, if you have an Espurr or Honedge that ''doesn't'' like you or is freshly caught, it won't care if you touch its ears or tassel.[[/note]].
*** The games actually have 31 storage boxes, though the 31st is only unlocked when Xerneas or Yveltal are caught to ensure that there is box space for them.
*** The games usually wish the player happy birthday on the day of their birthday. However, if the player was born on February 29th (meaning their birthday only rolls around once every four years), and it's not a leap year, Nurse Joy at the Pokémon Center will say "I know it's a day early, but happy birthday to you!"

* In the video game version of ''Series/WhoWantsToBeAMillionaire'', entering in one of the names of an actual million-dollar winner (such as John Carpenter or Dan Blonsky) will cause Regis to mock you and [[FailOSuckyname enter in a more disparaging name such as "Phony Cheats"]].

* ''TheLegendOfZelda''

* In the Old Clockworks area in ''VideoGame/Luigi'sMansionDarkMoon'', one room features a key guarded by two Slammers...only both of them are too distracted to notice Luigi. Most players would just capture the two ghosts and then grab the key, but if you instead opt to sneak past them, grab the key, and then leave without them noticing, they'll suddenly realize the key is gone and start looking around for it.

* ''VideoGame/ShinMegamiTenseiIV'' has the Terminal Guardian, a recurring enemy that you encounter guarding each one of Tokyo's terminals. His disguise depends on where you fight him, and the demon(s) he summons depends on how many times you've encountered him so far. His dialogue will always match his current disguise-demon combination, even unlikely combinations such as encountering him for the first time in his "Intuitive Man" disguise (which he wears in the final dungeons). What's more, every single one of his lines is ''fully-voiced.'' A comprehensive dump of his dialogue can be found [[http://www.gamefaqs.com/boards/672441-shin-megami-tensei-iv/69379037 here]].

* ''Franchise/{{Halo}}'' is known for having a surprisingly robust physics calculation engine, especially in ''VideoGame/{{Halo 3}}'' and ''VideoGame/HaloReach''. To say that everything is taken into account is not exaggeration. Bungie made it so that the game will account for such vanishingly small possibilites such as shooting ''through'' the open sides of a gunship, a sniper rifle round hitting several valid hard surfaces in a row at the right angle and ricocheting off each one (resulting in some truly sbsurd kills), and an enemy standing in front of a Spartan when their NighInvulnerability upgrade is activated getting killed because ''they were punched in the face when the activation animation played.'' That's attention to detail.
