If you are not one of the 2.4 million gamers who've already bought the new The Burning Crusade expansion pack for World of Warcraft then you'll be pleased to know its makers, Blizzard Entertainment, has made the game available as an official download so you won't even have to leave your home.

Although surprisingly not available at launch, it is now available via the account holders section of the website.

The Burning Crusade, the first expansion set for World of Warcraft, was simultaneously released in North America, Europe, Singapore, Thailand, and Malaysia on 16 January, and on 17 January in Australia and New Zealand.

Prior to the launch of The Burning Crusade, World of Warcraft was played by more than 8 million players around the world - with more than 2 million on North American realms and more than 1.5 million on European realms - making it the most successful subscription-based massively multiplayer online role-playing game in PC-gaming history.
