I like SNES Doom
Screenshots of the 32X version didn't look much different (though I'm judging from screenshots).
What was with Doom 64? It was so friggin' dark! Was this some boo-boo on the part of the developers. At times I wondered if it was intentially this dark, but it's obvious that this is not the case, considering reviews had the screen 'brightened' and also when you didn't brighten your TV up, you couldn't even read your life level or anything at the bottom. It was almost black.
