There are a few here, but there are plenty more in the official forums and YouTube who think you should just sell your house if you can't get a good Internet connection. Jay Wilson is still confused as to why people are upset when the hotel he was staying at had nine WiFi connections. "But the best way to play is online, so why would you want out of that?" (I don't know, Jay, make a public game in D2 and let me know what you think) This was edified by the fact so many people now consider Diablo II a bad game because of the rampant cheating and item site spam you experience online.

I don't think it would have taken that much to make a single player option given the "talent" these guys are supposed to have in their company. But you could hang on to that card and perhaps you can download a "patch" similar to SC2 that allows offline play. Be careful, though, not everyone has your best interest in mind when you get into third-party programs.
