I know I'm a late to the party with this one, but this afternoon is the first time I've actually completed this amazing game. Didn't even use cheats, took about 4.5 hours. End Nostalgia Mode, End Brag Mode.
Super Metroid was just an amazing achievement in atmosphere and story telling. It still is, in my opinion. I still listen to the OST now and again. I think it was the first game that ever gave me the creeps.
