World of Warcraft: Cataclysm is the fastest selling PC game of all time. If you’re willing to overlook the fact that it’s an expansion and not a full retail release. I am. The game it beat? Of course, its older brother, Wrath of the Lich King. Cataclysm has sold 4.7 million copies in a month.

A month!

In their article about the news, Kotaku has quotes Blizzard CEO Mike Morhaime jerking off, rightfully so, to the accomplishment:

We created thousands of new quests, introduced new lands to explore and extensively revamped the game world for World of Warcraft: Cataclysm, making it our biggest and most ambitious expansion yet.

We’ve been floored by the community’s response so far, and we’d like to thank them for their continued passion and support for World of Warcraft, and for helping Cataclysm reach this incredible milestone.

I played a good seven hours of Cataclysm last night, so I think it’s obvious where I stand. Despite playing it sparsely over the past month due to school, the holidays, friends, and Black Ops, it’s a gorgeous product. Here’s hoping it doesn’t consume me entirely like past expansions.
