It took a long time to get a version of Games Workshop's war game to the massively multiplayer space but so far it seems Warhammer Online is a success. Publisher Electronic Arts announced this morning that the Mythic Entertainment developed MMO has signed up over 500,000 players in its first week since its launch on September 18.

That number covers all of the areas that the game went on sale (North America, Europe and the Oceanic territories). EA claims that the the game has become the fastest selling MMO of all time (they have said they have received 1.5 million pre-orders for the game) but of course Funcom might have something to say about that.
