Games like Baldur's Gate, Neverwinter Nights, Mass E....- ok scrap what I was beginning to type, I'm gonna make it easier on myself:
Games like the ones BioWare makes are the solid proof that quality conquers piracy. PC games will always be pirated no matter what protection they add to it. The people that make the protection would know how to work around it and thus the hackers will at some point know this too.
If a game is great like the stuff Bioware and, yes, Blizzard brings out.. then it sells big. Period. Add shit like this DRM scheme, and faithful buyers will turn to piracy out of pure principle.
Your loss. Ubisoft. It's been fun.
Playing: Skyrim, World of Warcraft.
