the worst, clunkiest keyboard/mouse input >> control pad. that said, i'm getting REALLY tired of modern PC games not supporting extra mouse buttons. how much effort could it POSSIBLY take to get that right? 3rd party programs are irritating, time consuming to set up and switch around, and kludgey. and for the love of god, give me independent aiming sensitivity. ESPECIALLY if it's the goddamn sole means of combat! i can either jack up the sensitivity so high that the slightest twitch of the wrist points me in god knows what direction when walking about, or be able to aim and shoot at a reasonable speed in combat. not both.
