Yes! But only old-school here: NES, SNES, Genny. Old PC games (well, 1996-1999) because my computer is old and shitty. Playing Thief a year ago was an epiphany. Amazing. I love Jedi Knight (the first one). NES Metroid is my favorite game of all time.
I used to be into Counter-Strike, but my computer is shit, and I'm just not fucking good enough. Too hardcore for me. (Of course, when we upgrade to a better machine, I'll try again)
Hey Arg, I also have MAME, but I like stuff like Golden Axe II (my second-favorite game of all time), and Neo-Geo stuff. I had a fuck of a time finding that one; I have to check that it works properly.
