That's what gamecop...errr.. I mean....Probably because it's illegal still, no ?
Yea it's pretty funny if you get a crack for the game you already bought but you're still a filthy pirate, thieving honest people out of their money.
I doubt anyone would blame someone who bought AC2 for downloading the crack. Point its companies do tend to get a little carried away with their DRM schemes, to the point of hurting the customer.
