We all know 'em, I'm pretty sure we've all played them, and some of us love 'em. So, what's your favorite FPS game? Maybe oldschool FPS, like Doom? Or, maybe you enjoy Half-Life? It would've been useless to make it a poll, there's too many of 'em!
Personally, my favorite is an oldschool one that probably isn't as popular as some: Heretic.
