I can't reply to you drivebyacct... no idea why. But the games for the Xbox One MUST be serializable, how else would it know the difference between a install of a disc on one console and another? Put in disc. Installs to hdd, checks in with MS. Take out disc. Something stops you just putting that disc in to a mates Xbox One. So obviously they do have something similar to Sony's patent. Or every disc has a unique serial written to the small inner sector of the disc?
