Hats off to the staff Stardock had at PAX. I was amazed by the booth they put up, it was one of the best organized and largest booths at PAX, which I wasn't expecting from them. The staff members showing off and explaining the games were great, I discussed DotA with one of them and the influence it had on Demigod at some length. They really put their hearts into these games which usually results in very good games. I find that companies and developers that don't love their game end up producing shitty games (imagine that).
Anyway, Stardock really stole some wind from the larger companies at PAX. I would say only Valve's Left 4 Dead booth and Blizzard's Starcraft II topped Demigod (and maybe Fallout 3). Valve and Blizzard's booths were mayhem and they didn't have a very good method of turn over in terms of people getting to test the game. They were also under manned so you ended up getting almost no information about the game whatsoever besides gameplay.
