DC Universe attracted a million new players in the week following its transition to a free-to-play MMO.
Lorin Jameson, executive director of development at SOE Austin, said the new players were split 50/50 across the PC and PS3 versions.
"DC Universe Online's transition to free-to-play has been welcomed by the community and gamers with heroic enthusiasm," he said.
"Our business model philosophy of Free to Play Your Way makes DCUO accessible to every type of player so they can choose to play the game in a way that suits them best. We have a lot of exciting things coming up for players to enjoy in the game and are thrilled at the initial enthusiasm for the game's free-to-play transition."
Jameson said in September that Sony was altering DC Universe's business model because the cost of the game exceeded the company's original forecast.
