There is some protection that I don't know the name of but it prevents games to start if your using CD/DVD emulators, like Alcohol 120% and Deamontools. But a lot of people have those kinds programs. Then there are the program needs to check the disc for something, don't know hos it works but it was in Splinter Cell Chaos Theory. There isn't a solution that fits EVERYONE, so, some of us are just going to have to accept that there are people that would rather play a pirated version of a game than a "legal" version.
