Blizzard says World of Warcraft: The Burning Crusade has broken the day-one sales record to become the fastest-selling PC game ever in North America and Europe, with a worldwide total of nearly 2.4 million copies sold in the first day of release.
"The Burning Crusade has already exceeded even our most ambitious expectations," said Mike Morhaime, president and cofounder of Blizzard Entertainment.
"We're pleased that so many players are eager to see all of the new content that the expansion has to offer, and we look forward to seeing everyone online as additional players continue to upgrade in the days ahead."
Retailers are coming up trumps too: "The immediate popularity of The Burning Crusade once again shows that Blizzard consistently delivers what gamers want," said Robert McKenzie, a suit at GameStop. "In addition to setting a new day-one PC-game sales record at our GameStop and EB Games stores, the expansion garnered more online pre-orders than any other PC game in our company's history."
