While user-generated content has been a staple in SOE titles for many years, Player Studio is different because it's built on a for-profit foundation.
Players may "download sample geometry for actual in-game objects and through the use of third party art tools, learn how to develop, design and personalize items of their own." After an item passes the SOE approval process, it can be purchased by other players in the SOE Marketplace. Player content authors will then receive 40 percent of the net amount that SOE receives from the sale.
The service will initially cover both EQ and EQII. SOE's website says Player Studio is coming soon for both Vanguard and Free Realms.
