Ubisoft's Prince of Persia is shipping without any of the DRM which sunk EA's spore release.

Community Manager UbiRazz wrote on the official forum only retail copies are DRM-less, since the Steam-bought version will, of course, be tied to Steam's authentication system. 

Ubisoft had a few problems with both DRM and piracy.  Its Assassins Creed shipped with the problem that it always tried to phone home to authenticate itself. A DRM patch for Rainbow Six Vegas 2 broke the game for some people as it asked for the CD to be placed in the drive.  That would be okay, but some people had bought the game online, so they didn’t have a CD.

Ubisoft recommended using a CD crack from a warez group to fix the problem. The question is that if the Prince of Persia is released with no DRM what will Ubisoft do when it is pirated?   It is as if the company is putting the game out there to say that it expects to be ripped off.

Maybe it is hoping that users will be good.
