World of Warcraft: Cataclysm Declared 'Fastest-selling PC Game of All Time'

BOOM widget 306461 Ever keen to shout about its success, developer Blizzard today declared that World of Warcraft's third expansion pack, Cataclysm has become "the fastest-selling PC game of all time."

According to Blizzard's internal records and reports, World of Warcraft: Cataclysm sold-through 3.3 million units within the first twenty-four hours when it launched on December 7. The previous record holder, Blizzard said, was WoW's second expansion pack, Wrath of the Lich King, which sold 2.8 million on launch day back in November 2008.

The fantasy MMORPG currently has over twelve million 'subscribers,' in a loose sense of the word, though growth has slowed substantially from the early boom days.

This sales performance dwarves that of Blizzard's real-time strategy sequel StarCraft 2: Wings of Liberty, which sold over one million copies on launch day in July 2010.
