Hmm... in no particular order:
GameBoy Colour: Pokemon Gold and Silver, because they were amazing. Obviously xD
Playstation: Tombi - That game is so rare, and I'm so happy to have a copy. Best platformer EVER
GBA: Megaman Battle Network series. So much still to do T___T
Playstation 2: Persona series, Kingdom Hearts series, FFX, Dark Cloud series... basically, RPGs!
