Wow so that's quite the experience. Bought and installed Doom 2 on Steam, ran it through Steam. Once the game starts, the menu thinks you're on XBox. It is glitchy as hell and the menu prompts are all wanting me to use the Y, X, B, A, or RB and LB buttons. Mouse works sporadically. It was a bitch getting logged into Bethesda and downloading any addons and getting them enabled. Once I actually load up a level it seems to work fine though, I'll have to give it a shot tomorrow. Crazy oversight.
