World of Warcraft: The Burning Crusade Review - IGN

While most MMO developers release expansion packs on a fairly regular basis, fans of Blizzard's staggeringly popular World of Warcraft have had to wait for years to finally get a full-featured retail add on. When it was finally released a few weeks ago, it created a tremendous sensation within the WOW community. And it's no wonder why; the expansion adds two new races complete with distinct starting areas, a new trade profession, loads of high-level content and plenty of new dungeons, arenas and other PVP options.
