I stopped by GameCrazy on my lunch break and asked for the demo and yeah the guy told me I had to preorder. I've never even been to GameCrazy before so I was apprehensive about it, but the guy was like "You have to play this game" and he pointed to a TV off to my left that was playing the demo. He gave me the controller and holy crap it was intense. It's everything I thought it would be, I absolutely fell in love.
He kept talking about it while I was playing, he apparently went to CES with his manager or whatever and they hadn't heard of the game until then. They came across the game there and were hooked on it, they played it through a dozen or so times. He said the version at CES was much much more polished than the demo I was playing and to be honest I thought the demo looked fantastically polished so I can't wait to see what the final looks like. He mentioned that the CES build had better AI and that the demo felt kinda placeholderish in comparison. I ended up reserving the game and getting the demo, I can't wait until I can get home and crank up the surround sound. I'm so stoked for this game.
