Someone is telling me that SecurRom may be at fault in my download version in corrupting the game play as well...
And someone told me, that then it went and ate my neighbours dog and proceeded to dig up all my dead relatives.
Look. Div2 is not the first nor the last game on Steam to use other means of DRM than Steam itself. From Larian's track record i can also tell you that the DRM will almost certainly be removed with a future patch.
No sane person likes DRM. In many cases i have been forced to use cracks for my legally obtained older games, because the type of DRM used is incompatible with todays OS-es. There is no reason for such an obnoxious witch hunt though. Securom is certainly not the worst kind of DRM around these days. Have you played any Ubisoft games recently? Even Steam has its problems as a DRM, the offline mode is not the most bug free thing since sliced bread.
