There is even a thread on the Blizzard forum that has surpassed the 1,000 post mark, with majority of the complaints targeting Error 37 and Error 73, which mention that servers are too busy and that Battle.net is offline, respectively. Blizzard’s earlier response was this, “We’re aware that many players are receiving error 37 when logging into the game. Please note that this error indicates that all servers are full, and that we’re currently receiving a high volume of log-in traffic. We’re working to reduce the frequency at which players are prompted with this error message and ensure that everyone can successfully log in to the game and play.”
Hopefully they get it right, and do you agree to roll out a game that requires you to connect to the Internet even if you want to indulge in a little bit of single player action?
