Bullfrog for Populous, Geoff Crammond for Stunt Track Racer etc..., Cinemaware for Wings, and whoever did super stardust, and oh yeah I gotta mention Breathless, luv'd it
man just mentioning this stuff makes me want to go home and play some of my old Amiga Games
Electronic Arts for Powerdrome and (I think they did Indianapolis 500) I always thought indy 500 was very impressive
