Having acquired a SNES emulator for my PSP, one of the fine gems I've been playing recently is E.V.O. This game just plain rocks my socks. It's kind of like an arcade version of the upcoming Spore game. There's no where near as much customisation, but the funnest part is still coming up with some strange combinations. Some of my own personal favourites include a bird with the head of a T-Rex, a miniture horse and a lizard with a head twice the size of it's body.

How much do you love this game, cause I love it a lot.
