History GameBreaker / TurnBasedStrategy

** Some consider Desco of ''{{Disgaea 4}}'' to be a game breaker due to her powerful evilities (Increases attack of adjacent allies by 20%, gains 20% attack per third of total HP missing, and deals 50% more damage at the expense of receiving 30% of normal mana), high stats, and multitude of long ranged area attacks that become even better after a monster fuses with her (Yog Sothoth hits a 3X5 area, making it the biggest area attack in ''the entire series''). On top of that, she can be boosted to even further by a Beast Trainer.

** ''LUCT'' had that any class could equip any weapon. Simple, right? Yeah, but then you've got a ghost that teleports to the target, floats, and uses a hammer. Or you can just use two insanely powerful spears (The most powerful weapon in the game, the Spear of Longinus, is [[CaptainObvious a spear]].) and have your spear-using characters fight each other, hitting the target in the middle twice. (Does not work on Shaher, who stays in the corner.) And then there's SummonMagic...

* ''TacticsOgre'' has too many to count. Archers are available early on and will be useful for the rest of the game; unlike any melee unit they can attack at ridiculous range (greatly enhanced by having high ground) and aren't subject to counterattacks, can walk through water, and do just as much damage as a melee class. Mid-game you have summon magics which can basically one shot a target. By the end of the game you just pick how you want to be broken - do you prefer to kill everything on the screen within a few turns with dragon magic, or do you prefer to exploit the Retissue spell to make a character with 10x the stats of anyone else who can wipe out the entire enemy party before they even get a chance to do a SINGLE MOVE?\

*** Leonardo's Workshop WASN'T a game breaker because a veteran unit promoted by it would lose unit veterancy and a veteran lower tier unit (which got + 50% attack and defence) was regularly better than an inexperienced promoted one.
*** Actually, it really was. Having dozens of constantly state-of-the-art units would always trump the one or two veteran units your opponents could muster.

*** ''UFO Aftershock'' has also short range game breaker. GunsAkimbo. Well developed Cyborg/Ranger/Commando with 2 MP5 SMGs, armour piercing ammo and proper implants has greater range than assault rifles, 10 shot long burst (each shot has individual check for critical hit meaning that at least one critical hit in burst is virtually certain), very low aiming time (if enemy comes from beyond the corner it is possible to kill him before he finishes turning around) and (due to bug) insane movement speed, team him with Human Scout/Ranger/Commando who has much lower range but (even) higher critical hit chance and can spot living target from half the map. That duo can: shred anything into pieces at short range, suppress and outgun anything at medium range, rush from cover to cover so quickly that no enemy can even aim at them and obviously spot targets for snipers. Only drawback: huge ammo consumption.

* [[TheUndead Undead Hordes]] in {{Disciples}} 1&2. One can get ghosts with physical immunity pretty early in the game. And then [[CurbStompBattle easily kill]] all those [[GiantMook giants, trolls and krakens]] for large amounts of gold and exp, which in turn would allow to kill more dangerous enemies, such as dragons and enemy heroes. All handicaps enforced by such strategy are counterable. The most practical way to deal with such party is to [[NukeEm bombard them with most powerful spells available]], which works only slightly better due to the fact that your whole army consists of {{Squishy Wizard}}s (while the survivors of normal army would be easy pickings for exp). And computer doesn't do that.
* In the MegaDrive/Genesis port of Heroes of Might and Magic: King's Bounty, you're racing against the clock to defeat all the bad guys and save the king. Luckily, there is a spell called "Time Stop" that briefly freezes time. The Sorceress has many spell slots. The result of using these two together is that you can leisurely sail around picking up money (which always respawns). It also freezes all the random encounters on the map, letting you either easily avoid or only attack the weak ones for easy gold (and possible recruits). Yelling "Za Warudo" while using this exploit is stupid.

* In H-Game SengokuRance, you'll see a few people who will mention Omachi, Kenshin + Natori + Uruza + Aburako Dosan, and Yuzuhara Yuzumi + Mouri Teru pop up in discussions on who's the game breaking unit.

Archers are available early on and will be useful for the rest of the game; unlike any melee unit they can attack at ridiculous range (greatly enhanced by having high ground) and aren't subject to counterattacks, can walk through water, and do just as much damage as a melee class.

* ''{{Odium}}'' has the Attracting Device. When you deploy it on the ground during battle, monsters become hypnotized and won't attack you, instead trying to reach the device as fast as possible. Some monsters are immune, but most aren't (including, ridiculously enough, [[spoiler:human enemies]], making several potentially tough fights a doozy.) A fun thing to try is surrounding the device with your men to keep enemies from ever reaching it...

* In the release version of ''MasterOfMagic'', a single unit of Paladins could slaughter just about any enemy in the game. The supremely cool [[NinjaPirateZombieRobot Flying Invisible Warships]] were similarly powerful, and unlike Paladins they weren't nerfed in the patch.
** Not to mention that you could do [[NinjaPirateZombieRobot Flying Invisible ''Anything'']] with spells and equipment (for heroes).

* ''LUCT'' had that any class could equip any weapon. Simple, right? Yeah, but then you've got a ghost that teleports to the target, floats, and uses a hammer.

** The Custom Race option can be used to achieve a GameBreaker effect: simply slap both the "subterranean" and "aquatic" bonuses on your custom race. (Never mind that it makes no biological sense whatsoever.) The result: a race that can out-breed any other, given a planet with water. And since most of the easily colonizable planets are "terran" or "aquatic" by default... {{So Yeah}}. And more people means more production and science. Plus the subterranean bonus gives a big boost to ground combat when defending against invaders.
