[citation][nom]sten_gn[/nom]Single with on-line sucks, sorry but that is so stupid it is like a car on chain ... If it stay this way, i will not buy it. They only help pirates to earn with this. Sure as hell there will be whole lot of cracks for D III.Only legal buyers will be in trouble ...[/citation]
You can't "crack" Diablo 3. The files needed to play it aren't stored locally. You'd have to emulate a server on your computer (create your own private server, like with WoW), and then connect to it.
This wont completely completely stop piracy, but it will stop the vast majority of it.
