BlizzCon, Blizzard Entertainment's two-day celebration for enthusiasts of its popular computer games, converged this past weekend in Anaheim, Calif. Blizzard used the event to reveal its upcoming "Cataclysm" expansion pack for World of Warcraft, and also provided details of other games in development.

Cataclysm builds on a massively multiplayer game that's been in continuous play since 2004, and has been added onto twice already with expansion packs. While previous expansion packs have emphasized improvements that mainly benefit high-level players, Blizzard is going back to basics with Cataclysm by offering new content to attract both new and existing players.
