Sony Online Entertainment's DC Universe Online has seen a big increase in player activity since switching to free-to-play.

“One million new players have joined DCUO with a 50/50 split between PC and PS3,” executive director Lorin Jameson said in a statement. “DC Universe Online’s transition to free-to-play has been welcomed by the community and gamers with heroic enthusiasm.”

Hopefully the game can hold onto that player-base in order to stay profitable going forwards.
