L4D, L4D2, I'd have to re-install BF2, BF3, Borderlands, Warcraft 3 FT, Red Alert 3, Alien Swarm (it's free), Killing Floor, Any of Valves Source Engine games.
Also, Gov doesn't have all these games since he doesn't have a Comp, Does anybody have a spare steam account for the night? Or if we do all this offline LAN mode, he shouldn't have a problem, right?
Once we get a date set, I'll make sure to get my steam account up and running in offline mode before hand.
