Great game. DRM kind of sucks though...
This only applies to the downloaded version - the retail boxed version will work like other games, where everyone can have their own profile and settings - the downloadable version ONLY allows the profile that you were logged in as when you buy the game to run the game at all. This is TERRIBLE for people who (like me) have teenagers in the house and we all want to play but not share a profile for rankings. I'm going to see if I can get my money back and go buy the retail version. Something tells me this is going to be an uphill battle...
The game itself is great. Top notch controls, graphics and gameplay. The DRM really takes a lot of the shine off though :(
