My brother wants to buy the game, and I'm a fan of Diablo myself. Knowing that a Battle.Net account is needed to play, does that lock it to one account per copy, or can I just log in to my character with my own account? Regardless, whether I need one or two copies, I'm going to buy the game, but I just want to know before I get into it.
And yeah, I realize how dumb of a question this is. Shame on me.
