It wasn't too long ago that the MMORPG Age of Conan: Hyborian Adventures decided it would drop a subscription plan and relaunch as a free-to-play title. The game would be called Age of Conan: Unchained and allow free and premium gamers the chance to play side-by-side. Since that switch to an F2P model, Age of Conan has doubled in revenue and attracted 300,000 new players to Funcom's world. The total revenue doubled to what it was before in a few short months, plus the uptick in players, means that Age of Conan: Unchained is another entry in the success of turning a subscription-based MMO into a free-to-play model. The Lord of the Rings Online also made a switch to F2P, and its developer Turbine announced in January of this year that its revenue had tripled since the switch. So, maybe there is something to be said about the F2P model for MMOs after all, especially in light of the current economy. Age of Conan offers an in-game store to let free gamers purchase items, while you can always become a premium subscriber to gain access to all of the game's features. Additionally, Age of Conan: Unchained will receive a new add-on later this year called Savage Coast of Turan to tie in to the new Conan the Barbarian movie releasing next week.
