Amiga: A whole crapton of games that I can't remember now. My dad's old student passed down the system with his entire game collection to me, so yeah, there was a lot of stuff there.

PC: Either Tomb Raider, Croc, or Diablo, I can't really remember which.

Gameboy: Warioland 2 (this game was awesome)

Gameboy Color: Pokemon Yellow

Gameboy Advance: Harry Potter and the Philosopher's Stone

Playstation 2: Kingdom Hearts, FFX, FFX-2, some formula 1 racing game

DS: Pokemon Diamond

PSP: FFT: The War of the Lions, Breath of Fire III

3DS: Pokemon X and Bravely Default

PS Vita: Persona 4 Golden, Danganronpa 2, Final Fantasy X/X-2 HD

I also played a lot on the Wii and Wii U, but I don't really own the systems, since they're at my parents' house so they mostly belong to my brother now.
