They're really the only one to stand the test of time as far as gaming goes lasting in the US market 30 years now. For those old enough or just got into it more recently it doesn't matter, it doesn't even matter if you have one on every system, but what's your favorite game on the systems you've owned/used?

Anything is fair game, even the more unpopular and obscure too. NES/Famicom, SNES/SFC, Gameboy, GB Color, GB Advance, DS, 3DS, N3DS, Wii, Wii U, N64, GameCube, Virtual Boy, Pokemon Mini, etc. Try and keep it to one if at all possible just to see some variation in the lists.
