Can users modify, resell or transfer content once they purchase it?
Users are free to modify any content they purchase from the Marketplace.
All items sold are non-transferable, and users cannot sub-license the content for further redistribution, whether or not they have modified it. Users cannot buy your content and then distribute it to other developers to use in other projects, for example by listing it on the Marketplace or another store themselves.
