Abstract: A system for providing interoperability of electronic games independently-operable from one another includes a network entity and a client. The client can interact with the network entity to play a master electronic game using shared attributes otherwise configured for use in a subordinate electronic game, where the client can interpret the respective shared attributes for use during play of the master electronic game. During play of the master electronic game, the client can receive a selection of at least one subordinate game from within the master electronic game. In response, the client can initiate the selected subordinate game for play using shared attributes otherwise configured for use in the master electronic game and/or another subordinate electronic game. Similarly, the client can interpret the respective shared attributes for use during play of the selected subordinate game.

Abstract: A system for managing a contact or buddy list includes a network entity, such as a game server, capable of providing a contact list identifying a plurality of members, where each identified member is associated with at least one criterion related to interaction of the member with the network entity. The network entity is also capable of dynamically creating at least one criteria-screened list based upon at least one of the criteria associated with the members listed in the contact list. More particularly, network entity is capable of dynamically creating the criteria-screened list based upon at least one of the criteria that is independent of a current presence of the client with respect to the network entity.
