How specific is the description of DRM on retail boxes?
BTW, neckthrough already said it: At least some of the DRM counter-measures are against rental stores and resellers (and any company bigwig that still thinks it stops pirates should be fired).
Sooo..it needlessly annoys buyers. Which will lead to more pirates.
And another thought: there was a law/agreement/whatever that as long as you had proof that you indeed possess a genuine copy of a game, you could freely copy the disc (for personal use only, of course). AFAIK that hasn't changed (not that I bother reading the EULA), so... buying a game and then downloading a pirated version wouldn't be against the law, again, AFAIK.
Also ........... I forgot.
