It was one year ago, today, that the blood elves and draenei joined the armies of Azeroth, and the Dark Portal was opened to the beautiful and terrifying vistas of Outland. On January 16, 2007, The Burning Crusade was released and sold almost 2.4 million copies worldwide in its first 24 hours of release, winning multiple awards from industry representatives. Since that time, World of Warcraft has reached the epic milestone of 9 million subscribers worldwide, and players have discovered the might of the Burning Legion, fought against the allies of Illidan in Serpentshrine Cavern and Tempest Keep, and even faced down the Betrayer himself in the Black Temple.
For those who have not yet had the chance to venture into the perils of Outland, a free trial of the Burning Crusade is available for download. For players yet to experience World of Warcraft, a free trial of the original game is also available.
