I'm into games in general. 80's, 90's, 2000+. Consoles, computers, arcade, whatever. I bust out my NES and my n64 from time to time, and I play Doom, Half Life, and modern PC games roughly the same amount. Whatever I am in the mood for.
Here is another retro confession, DOS PC games aren't necessarily my favorites. I like DOS games, but honestly I have a weird soft spot for mid to late 90's and early 2000 3d games on just about every platform. I know they are kind of bad, but I kind of like that I guess. I find their odd quirks charming and deeply nostalgic.
