The list of things which had a big impact on me is too long to mention, but DOOM is right up there with Mad Magazine and monster movies. While I didn't hate DOOM 3, I love that the new colors and some of the art design reflect the 90s graphics that helped make the original games a mind-melting addiction. DOOM works better as a nonstop action game with horror (and SF) elements rather than going full-blown horror. It looks like they're hitting that mark.

read the hyper-90s comic at Doomworld... it's radical, dude
