The free-to-play version of Funcom's Age Of Conan MMO has doubled the game's revenue in its first month.
Age Of Conan: Unchained runs in parallel with the subscription-based version, and more than 300,000 new players have registered since its launch.
"The launch of the hybrid business model has been very successful so far," said Funcom CEO Trond Arne Aas in a statement.
"The activity levels on the servers are booming with a four-fold increase in players during July, we more than doubled the revenue generated from the game, and we have experienced a positive development in subscriber numbers. This definitely gives us great hope for the game's future."
Unchained gives players access to all of the levelling quests and outdoor playfields that launched with Age Of Conan. Additional items are purhcased must be paid for, and expanded content is only available to premium subscribers.
