Sega Genesis - I recall both watching my cousin play Aladdin and The Lion King and as well as playing them myself on her console. I honestly forgot about that until just now.
SNES - My game was Killer Instinct. My brother was better at the game than me, but I got pretty good by playing him and getting killed over and over again. Super Mario Kart (back when Rainbow Road was actually hard) and Vortex were also really fun. Also had the converter to play the Gameboy games on there like Donkey Kong Land, Super Mario Land 2 and Wario Land. Tetris, too.
N64 - Mario Kart 64 was fun. Trying to remember some of the other games I played, but I'm drawing a blank.
PS2 - I played The Godfather on there and beat it. Pretty easy. Also played Madden 08 and Scarface. I inherited my brother's system and he mostly had sports and racing games. Haven't played many of the other games for that console.
Anything beyond PS2 I've never touched. Time spent playing games is time I could be watching anime.
N64- I was dubious about video games at that time. I thought they were probably a waste of time. Then I met Dr. Mario.... that was me eating my words. I loved that game and was sure it was improving my hand-eye co-ordination.
