Abstract: A content delivery system that uses a graphical user interface to introduce users to and allow them to select from available content. A game delivery system that uses game players, such as emulators, to execute software written to run on a plurality of game platforms. The systems include a scalable, dynamic interface that launches and manages game players in a manner that is largely transparent to the user, and a combination of linear and on-demand content provides users with a managed gaming experience not unlike that of interactive television. In addition, the system includes a graphical user interface for allowing a primary user of an account to set user-specific controls for one or more users listed on the account.
