As Joe requested, this is a revival of a topic listed in the archives of the old board. The idea here is to list each of your systems and say what your favorite game for that system is. I'll start...

Atari 2600--Kaboom!
Atari 5200--Pengo
Atari Lynx--Klax
Atari Jaguar--Tempest 2000
ColecoVision--Donkey Kong
TurboGrafx-16--Keith Courage (it wins by default...it's the only game I own for the system right now)
NES--Super Mario Bros. 3
Super NES--Super Punch-Out
Game Boy Color--Super Mario Bros. Deluxe
N64--Mario Tennis
GameCube--Resident Evil
Sega Genesis--Can't decide...never played this system much which I've only had a short time
Sega Saturn--World Series Baseball '98
Sega Dreamcast--Soul Calibur
Sony Playstation--Bubsy 3D! Okay, not really...a tough call since I've so many games for it but I guess I'll go with Medal Of Honor.
I think that's all my systems...
