it has a type of drm on it that only allows 3 activations. After that you have to phone the company to get more activations
go to the steam forums for the game to see what I am talking about. Other than that everything I haqve read about the game looks pretty sweet man. I wanna buy it real bad but the drm thing is a big turn off. It has the steam drm and the built in drm in the game. Even the store bought copy has the drm with the activation.
