I have a NES, SNES, N64, Gamecube, Wii, PS1, PS2, PSP vita, Xbox 360, Gameboy Color, Gameboy advance sp, and a Nintendo DS.
I have 4 games for my NES, I have Duck Hunt, Mario, Kirby, and the Addams Family. I have 42 games for my SNES. I have 6 games for the N64, I have Super Mario 64, Pokemon Snap, Mario Kart, Starfox, Legend Of Zelda OOT, and Kirby. I have 17 games for my Gamecube, 13 games for my Wii, somewhere around 120 games for my PS1, around 200 games for my PS2, I only have FF X HD for my Vita, 32 games for my 360, 14 games for my Gameboy Color, 7 games for my SP, and 11 games for my DS. I've had my NES for like 15 years, SNES for 16, Xbox for 2 years, and that's really all I can remember around when I got it. I don't really ever clean my systems. That's probably bad, but when a system breaks down I just buy a new one so it's not a big deal, except for my 360 which I have had cleaned professionally once a couple months ago because it started overheating a lot and I'm not losing all of that data. My most favorite system would have to be either my Gamecube or my PS2 and I play those almost every time I decide that I want to play a game because there's so many memories in all of those games and any time I play them I just feel happy.
