Diablo III may have had its fair share of issues since launch, but that still hasn’t stopped people from continuing to pick up the game — a rather large number of people. Despite the problems people have experienced with things such as logging in and the auction house, the amount of copies sold has gone up nearly 4 million since Blizzard announced the first week sales total in May.

At the end of the first week, the game had already sold 6.3 million copies.

Of course, not all of these were for the full $60 standard edition price, as World of Warcraft players recieved discounts or got the game for free when signing up for the annual pass. On the other hand, some people dished out about $100 for the collectors edition. (I tried to find a number on this but could only locate an estimate of 70,000 — whether this was just a first run number or accounts for all of them is unclear.)

When discussing Diablo III at yesterday’s conference call, president of Blizzard: Mike Morhaime told analysts that D3‘s real-money auction house is meeting expectations in regard to revenues. He also said that Blizzard will continue to expand the service but elected not to specify how much money the RMAH is actually bringing in.
