VideoGame/IWannaBeTheGuy has spawned a number of fangames.

[[index]]
* '''''VideoGame/TheDrossGame2''''': Created by Rogelio Díaz, in a tribute of a venezuelan blogger named Angel David Revilla (Creator/DrossRotzank). He writes the blog "El Diario de Dross", a very sadistic and black-humor diary in spanish language.
* '''''VideoGame/FangameTheGame''''': Created by [=VertigoElectric=]. Notable for being the only major fangame to be created with [=MMF2=]. Also, [[EverythingIsTryingToKillYou the mouse kills you]]. Unfortunately, it's been in DevelopmentHell for a while. In addition, it isn't really a fangame, it's more like an "inspired by IWBTG" game according to [=VertigoElectric=].
* '''''VideoGame/IWannaBeTheBoshy''''': Created by Solgryn. Like Fangame, it was also created in [=MMF2=]. Contain gratuitous swearing, and lags horribly on some computers, but is quite fun otherwise. Also worthy of being one of the most visually stunning fangames out there.
* '''''VideoGame/IWannaBeTheFangame''''': Created by Tijitdamijit and his friends. It is the most popular fangame to date, and has been submitted to Moddb.
* '''''VideoGame/IWannaBeTheGB''''': Created by Ashimoto. Note: GB does not stand for Game Boy.
* '''''VideoGame/IWannaBeMyself''''': Created by [=SirRouven=]. This game contains less cheap kills, [[EasyLevelsHardBosses but the bosses are even harder.]]
* '''''VideoGame/IWannaBeTheRockman''''': Created by Dakaarts. This game replaces The Kid with Franchise/MegaMan and also borrows a lot of influences from his franchise. It doesn't have quite as many cheap tricks as most of the other fan games, but it's still pretty insane. It was unfortunately abandoned in 2013.
* '''''VideoGame/IWannaBeTheShrineMaiden''''': Created by holy. Based on Franchise/TouhouProject. Has a sequel.
* '''''VideoGame/IWannaBeTheTribute''''': Created by [=Shaman666=]
* '''''VideoGame/IWannaBeTheUltimatum''''': Created by Matt and Kyle.
* '''''VideoGame/IWannaKillTheKamilia''''': A series of brutally hard medley fangames.
* '''''VideoGame/IWannaSeeYouSuffer''''': Created by [=UltraJMan=], who started creating it following his hellish, rage-inducing run through ''VideoGame/IWannaBeTheFangame'', and it is far more sadistic than IWBTG or IWBTFG. Currently in its alpha stage, it starts you off on an agonizing descent through a spike tunnel that you will spend at least a few dozen tries getting through and it just gets worse from there. One only wonders what [=JMan=] was thinking when he made this. [[spoiler: He was getting {{Revenge}} on everyone who encouraged him to play IWBTFG.]]
* '''''VideoGame/{{Pickory}}''''': Created by Storyyeller. Unusually for fangames, it was written from scratch in C++, rather then using an engine such as Game Maker or [=MMF2=]. Due to the different engine and differing design philosophies, it contains a number of differences from most other fangames. It is also the only fangame designed to easily support {{Speedrun}}ing, with built in features including savestates, replays, and single frame advance.
* '''''[[VideoGame/YoureTheKidNowCharlieBrown You're the Kid Now, Charlie Brown]]''''': Created by [[Creator/BlueSkyStudios The Blue Sky Studios marketing team]] in celebration of [[WesternAnimation/ThePeanutsMovie The Peanuts Movie]]. This game depicts The Kid in the Charlie Brown art style. This game is fairly short, having three levels and a fight against Mecha-Woodstock.

!!Tropes common to fangames in general:
* BulletHell: Many of the bosses seen in ''I Wanna Be the Guy'' fangames, especially those made in Japan, tend to spend the battle raining down projectiles on the player.
* FanSequel: In play with any fan game with a length that matches the original game.
* PlayableMenu: Of course, if the game doesn't throw ya into the first level straight away. Naturally, the menu CAN BE the first level.
** ''I Wanna Be The Better Er- Engine'' not only allows players to select difficulty on the first level. They also can remap the controls right there.
** ''Pickory'' has a collectible secret which can only be reached by jumping off the menu screen before starting the game.
* TrollFic: VideoGame/IWannaBeTheGuy doesn't have troll fanfiction, but it does have troll ''fangames''. [[http://kayin.pyoko.org/iwbtg/forums/index.php?topic=10272.0]] and [[http://kayin.pyoko.org/iwbtg/forums/index.php?topic=15986.0]] are some of the more obvious examples, though theoretically, [[PoesLaw any of the horrible fangames could be secretly trolls]].
