I was big into DC for a while, then my friggin joystick snapped in half one night when I was flying and I couldn't play. Never have replaced it. Ahh well.
Playing Dawn of War right now.
CS/HL2 sucks. I could go into why, but it'd be met by accusations of "omfg I can move planks of wood around!"
(the grass looks like pubes, the texturing sucks, the shadows don't work right... I could go on but in all honesty only Wormgod might understand my beefs with the game)
