Denuvo. One of the problem creating DRMs.
Sure, that's almost all of them, and they are quickly defeated and worthless, but still screw with your computer.
Guess after I get BL3, assuming I do, I'll have to go get a crack to remove Denuvo.
(I tend to remove DRM from all games I buy, as I've have lots of bad experiences with DRM over the years.)
I wonder how many days it will take to be cracked this time.
