A monster catching game with a difference, where you can merge the monsters you catch to get over a million different combinations of appearances and attacks. Released around the same time as many Pokémon clones, so was largely looked over...
It's fairly new and hasn't got that much stuff on it yet but it's getting better. Only one fan at the moment (me) and I'm feeling a bit like a loner so is anyone else a TimeSplitters fan?
