I rarely play demos. The only demos I can remember actually downloading are Left 4 Dead 1/2, Dead Space 2, Resident Evil 5, and Mirror's Edge. All of those games I planned on buying except Mirror's Edge. If I'm ever very excited for a game, I'll download the demo because I want to get to it as quickly as possible. I know, that's completely stupid, but I just can't wait until February to play Bulletstorm! I have to get a taste.
