The retail recession isn't complete! After a launch that included midnight parties and lines outside of Best Buy stores (pics here) Activision Blizzard Entertainment (ATVI) now says it sold more than 2.8 million of its World of Warcraft expansion pack, Wrath of the Lich King, on the first day of sales, making it the fastest-selling PC game of all time.The company got some love on Wednesday from Citigroup analyst Brent Thill who notes it's other slam-dunk title, Guitar Hero, is seeing strong demand for the $190 "Guitar Hero: World Tour" package both online and at retail.

There won't be many winners this Christmas season, and while video game sales are expected to be slow along with everything else, Activision may be one of an increasingly small handful of winners. "We're grateful for the incredible support that players around the world have continued to show for World of Warcraft," said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. "Wrath of the Lich King contains some of the best content we've created for the game so far, and we look forward to seeing even more players log in to experience it in the days ahead."
