Adventure game Journey--which was released on March 13--is the PlayStation Network's fastest-selling game of all time, Thatgamecompany creative director Jenova Chen announced today on the PlayStation Blog. Journey has traveled all the way to the bank.

　　Specific sales figures for the game were not revealed, and as of press time, Sony had not responded to GameSpot's request for comment.

　　Additionally, Chen announced today that Journey's soundtrack--composed by Austin Wintory (Grace, Captain Abu Raed)--will arrive on the PlayStation Store and iTunes on April 10. The soundtrack will also see a "limited" release on CD.

　　Today's announcement follows word from earlier this morning concerning Thatgamecompany president and co-founder Kellee Santiago's departure from the company. Other "key" staffers are also believed to be on their way out of the studio as the company goes through "big changes."

　　No word has been offered concerning the next project from Thatgamecompany, but a studio job listing indicates a new project at the outfit will feature a "full-scale online service" capable of supporting hundreds of thousands of users.
