I played a Move demo today at Best Buy. It was pretty obvious the fat guy trying to extoll its virtues to me was some kind of ...whats the derogatory term for playstation fanboy again? In case you were wondering, he did work there.
Anyway, the only game I played was the sports champion ping pong. Game is fucking hard. It is accurate though. I guess I'm too used to WSR ping pong to give it a fair assessment, but I couldn't figure out how to place my shots well. *shrug*
I also tried a gran turismo demo and was surprised you still had to brake and accerlerate with the face buttons. Maybe there was an option I missed.
