The Burning Crusade

Today (or rather, yesterday) the expansion to the World of Warcraft, titled the Burning Crusade was released. It seems that the expansion has sold around 2.5 million units in North America and Europe only! That's a really, really impressive number. Seems that WoW addiction is more serious than I thought. For those that has been living in a vacuum, WoW is the most popular MMOG (it's a MMORPG.)
