Consoles I've owned:
SNES: Super Mario World
Game Boy: Zelda: Links Awakening
Genesis: Sonic 2
N64: Pilotwings (though Mario 64 was the first game I bought when I got mine)
PSX: FFVII
PS2: It was either Kessen or DOA2, though I can't really remember at this point.
GC: Resident Evil
PC: Some old DOS game called Sleuth is the earliest game I remember playing

Systems I haven't owned:
NES: Either Mario or Duck Hunt. They were both on the same cart so who knows.
Virtual Boy: Some sort of Star Fox like flight game
Gameboy Advance: Castlevania. I think it was Harmony of Dissonance, though it may have been Circle of the Moon.
DS: Mario Kart
Xbox: Halo
Atari: Pong
TurboGrafx-16: Bonk's Adventure
Saturn: I think it was Radiant Silvergun, though VF2 is a possibility.

Funny, I didn't realize how many systems I've actually played until right now.
