Warhammer Online: Age of Reckoning has reached the 500,000 accounts level in less than a week. Mythic has sent out a press release announcing the achievement which you can read below:

The Armies have assembled and the Worldwide WAAAGH! is Underway! Mythic Entertainment, an Electronic Arts Inc. (NASDAQ: ERTS) studio, today announced that in the first week since launch over 500,000 new players have registered for fantasy MMORPG, Warhammer® Online: Age of Reckoning™ (WAR), in North America, Europe and the Oceanic territories. EA's most highly pre-ordered PC title, WAR has now become the fastest-selling new MMO of all time.

"In just one week we have a half a million people playing WAR online, and the ranks of Order and Destruction are growing at a record-breaking pace for a new MMORPG," said Mark Jacobs, co-founder and general manager of Mythic Entertainment. "We spent years working to provide players with the most stable, epic, and polished online world we could, but it is the players that have truly brought the Age of Reckoning to life."

Based on the popular tabletop war game from Games Workshop, Warhammer Online: Age of Reckoning features revolutionary Realm vs. Realm™ conflict that will provide an engaging battleground for years to come. Available for PC and rated "T" for Teen by the ESRB, WAR is now in stores everywhere at an MSRP of $49.99. For more information, visit http://www.warhammeronline.com/

What will be telling is whether or not Warhammer can maintain this high level of interest in, say, a month or so. Time will tell but in the meantime, CONGRATS!
