Before Doom, there was Wolfenstein 3D. It was a "Doom Clone" before there was a Doom to speak of. It's bascially the same game as Doom it just replaced Demons with Nazis. With all the controversy that surrounded Doom back in the day, why did no Congressmen or Senators ever speak of Wolfenstein 3D? Shooting demons from hell is evil, but damn if you hate on a game where you shoot Nazis, then you're Un-American.
This is what the PC version looked like. Not exactly ground-breaking graphics today, but back then it was on the top of it's class. Kids were begging parents to buy them ultra-nice PCs or computer parts so they could play this alone. I've never played the PC version, and I never will. However I did play the SNES version of Doom, and even though I don't really like Doom I didn't think it was a bad port.
This is what Wolfenstein 3D on SNES looks like. Muddy, blurry, and just plain hideous. They take out pretty much all the Nazi logos, and everything. Apparently they wanted to release it in Germany (which pretty much bans anything Nazi unless it's about history and education), and it still got canned in land of BMW, Beer, and Bratwurst.
I really could not stand playing Wolfenstein 3D on SNES for more than a few minutes straight. It's incredibly awful in almost every way. It's an aging game even in perfect or upgraded form, and it doesn't help when the graphics and control are almost as bad as our former enemies.
