World of Warcraft mostly referred as WoW, a massively multiplayer online (MMORPG) game by Blizzard Entertainment has set record sales of 4.7 million copies in first month with their third expansion set “World of Warcraft: Cataclysm.”

Blizzard Entertainment, a subsidiary of Activision Blizzard released the first expansion of the game “The Burning Crusade” on January 16, 2007 and the second expansion “Wrath of the Lich King” was released on November 13, 2008. It is presently the most subscribed MMORPG game in the world with more than 12 million subscribers in the world as of today and holds the Guinness World Record for the most popular MMORPG by subscribers.

Mike Morhaime, CEO and cofounder of Blizzard Entertainment in a statement said that “We created thousands of new quests, introduced new lands to explore, and extensively revamped the game world for 'World of Warcraft: Cataclysm,' making it our biggest and most ambitious expansion yet.”

Most of the sales for its latest version which was released on December 7, 2010 took place in the first day as 3.3 million units were sold.

One of the biggest gimmicks behind this new expansion is the destruction of world of Azeroth by the evil dragon Deathwing the Destroyer. The Deathwing who was last seen in Warcraft II has been spending his time healing himself. The destruction causes a sweeping cataclysm which reshapes much of the world’s surface.

Other major environmental changes include the redesign of the Eastern Kingdoms and Kalimdor areas introduces during the launch of World of Warcraft in 2004. And the new area like Mount Hyjal and Deepholm opens up whereas the Worgen and the Goblins will emerge as new playable races. And keeping the new cataclysm theme in mind, new race class combinations are introduced and players will be able to fly their mounts in the old world of Azeroth.

Moreover the level cap has been raised from 80 to 85 and professional skills cap raised from 475 to 525.
