According to the company, this makes Warhammer Online "the fastest-selling new MMO of all time," with studio VP Mark Jacobs adding that "the ranks of Order and Destruction are growing at a record-breaking pace for a new MMORPG."

The last high-profile PC MMO release, Funcom's Age of Conan, netted 400K players in the week following its May launch. Funcom later claimed that Conan was "the biggest MMO launch since World of Warcraft," a record that Mythic appears to be closing in on.
