Teenage Mutant Ninja Turtles Tournament Fighters was released on three different systems but it was essentially three different games as opposed to being ports of the same game. While the same basic concept exists in all of them, that is the turtles have to fight in a tournament, the story, characters, locations and controls among other aspects of the game vary greatly between the different versions. This game was released by Konami for the NES (the last Konami game for this system), Super NES and Sega Genesis between 1993 and 1994.
In the Sega Genesis version pictured above, the player travels throughout Dimension X fighting clones of themselves among other enemies. The general consensus seems to be that the Super Nintendo version is the best by a slight margin and the NES version is not surprisingly the worst but they are really all different games and all worth having if you are a Teenage Mutant Ninja Turtles fan.
