It was really great! I played a lot of arcane legions which is a warhammer fantasy-esque game from the guy who started Wizkids back before it was sold off to topps. It's a pretty solid game and it allows you to design your own legal units which is nice since that will counter the game balance issues out of the box.
I got to play a few board games I have been wanting to play. Middle earth quest was sprawling, but didn't grab me on a demo (especially at $80). Small World was an ok pseudo-wargame, but was too lite for my tastes. Dave, Mike and I played Drakon, a little dungeon quest tile game, which was a quick, screw your neighbor game... quite fun! I also demoed Android which is hard to explain but is very story-centric game set in a bladerunner future in which your characters need to solve a murder (kinda). The demoer was maybe the worst demoer I've ever seen, but the game intrigued me enough to buy.
I also got to play some Warcraft minis (didn't qualify for the championship event), Navia Dratp, Dominion, and battlelore.
I didn't get to play, but purchased the pegasus expansion for BSG and Colossal Arena which is a really great quick betting card game.
