The rigamarole is always the same: Big game is released, problems ensue. But for Diablo III, the launch was bigger—twelve years in the making. And the problems? They seem bigger, too. And when that happens, people get angry.
As previously detailed, Diablo III's "always-online" feature was problematic to say the least, and players have been dealing with errors like Error 37 and Error 3003. The whole thing hasn't exactly been smooth.
