Blizzard Entertainment today announced plans for a Mac OS X version of World of Warcraft, its upcoming massively multiplayer online role-playing game. “World of Warcraft takes place three years following the aftermath of Warcraft III: The Frozen Throne, where a great tension has settled over the ravaged world of Azeroth. As the various races begin to rebuild their shattered kingdoms, new threats, both ancient and terrifying, have arisen to plague the world once again. Players must explore the lands of Azeroth, forge fellowships with other players, and build their strength in order to prevail.”
