All products sold on the Marketplace are licensed to the customer (who may be either an individual or company) for the lifetime right to use the content in developing an unlimited number of products and in shipping those products. The customer is also licensed to make the content available to employees and contractors for the sole purpose of contributing to products controlled by the customer.
Each such product built using content purchased from the Marketplace must be a standalone creative work (such a game, simulation, or video) in which the Marketplace product is merely a component and not the primary focus.
