Game: Rawr

For as long as Game Freak's Pokemon games have been around, other game developers have been inspired to add their own spin on the monster-collecting formula. Some studios just ape the games directly by scribbling over Game Freak's designs with a crayon and calling it a day. Other studios, like Tremor Games, make a real effort to separate themselves from the clones with titles like Rawr. Rawr maintains its own identity with the help of an intriguing battle system and over-the-top grunginess, but its mechanics need some tightening up before it can even think about slaughtering Pikachu.
