It seems that Diablo 3 will blow past most analysts' estimates for the game's sales. Blizzard revealed today that the PC action RPG sold over 3.5 million copies in its first day of availability.
The 3.5 million in sales were from players who bought Diablo 3 by itself on May 15th. Another 1.2 million signed up for the World of Warcraft Annual Pass, a twelve-month commitment to WoW that includes a free copy of D3. Technically, then, the game's one-day haul is 4.7 million.
Sales continued to be strong throughout the week. Blizzard says that 6.3 million copies have been sold in total. They note that the sales figure doesn't include Korean Internet game rooms, where it's the top-played title by a large margin.
This total is much higher than the 3.5 million and 5 million predicted by analysts. Those two estimates were for D3's entire first year, mind you. Seems that they really underestimated the draw of the series.
Blizzard coordinated a massive global launch for the game on May 15th. Over 8,000 retailers in North America, Europe, and parts of Asia opened at midnight to sell the game to eager fans. Blizzard also sold the game digitally through their own online store in those countries as well as Mexico, Argentina, Chile and Brazil.
D3's huge sales turned out to be a double-edged sword for Blizzard. The game's servers were overwhelmed by players on launch day and sporadic problems continued throughout the week. Blizzard apologized for the connection issues on Thursday and announced they would be delaying the real money auction house for the game so that they could focus on server stability.
