Burning Crusade

Blizzard announced that almost 2.4 million copies of Burning Crusade were sold worldwide during the first day of the expansion's availability. Nearly 1.2 million copies were sold in North America and over 1.1 million copies were sold in Europe, making the expansion the fastest selling PC game ever.

Over 5000 retailers opened at Midnight on January 17 to sell more than half of the 4 million copies they received from Blizzard. If you're looking to buy, Blizzard is advising that you call ahead to make sure the store has it in stock. But last night, my local Best Buy had a massive fully-stocked display.
