What about diablo2 lod ?

Dude, just do what I do. Fucking LAN! You don't need a original CD Key to have a TCP/IP game anyway. And despite what everybody else says, fuck Battle.Net. Open is full of dumbasses who think they're extremely good because they spent six hours hacking their character to shit. And Closed is full of cocky pricks who do nothing but brag about how many hardcore characters they've beaten the game with. Trust me dude, just LAN with some of your close friends. Way better.
