The latest sales figures come from a Blizzard company profile and you can probably expect to see a press release about it before too long as well:
The company’s most recent release was World of Warcraft, the massively multiplayer online role-playing game (MMORPG) based on the award-winning Warcraft series. It launched on November 23, 2004 in North America, Australia, and New Zealand, and promptly shattered all sales records for a PC title, as well as setting records for account creation and peak concurrency for an online game. It became the fastest PC title to sell over 240,000 units, with the biggest day one sell through in PC history. In less than three months, it had already sold over 800,000 copies in North America. With a subscriber base of more than 750,000 players and peak concurrency of over 250,000 users, World of Warcraft is now the biggest online game in North America.
WoW is already being called the first mass-market MMORPG, but that title won’t be official until it manages to break the 1 million mark. Still the incredible success of this game in such a short period of time is something the folks at Blizzard must be very happy about. Now if they can just get rid of the lag in Iron Forge and other areas with lots of players present they’ll end up ruling the world in no time.
