Abstract: An gaming system comprises a game server with which client systems can interact, wherein users play interactive games based on the users' team associations, wherein virtual matches between teams are determined, at least in part, by real-world league schedules, and wherein the gaming system presents game results by team for a league where the virtual match results for various teams in the league are determined by results of individual games played between users representing those teams while playing the games. Individual users for individual games can be associated with teams of their choice, assigned teams or assigned to teams that rival other teams that the users' preferred team is a rival of. The client systems can be computers, handheld devices, gaming consoles, or the like. The client systems can include local game code or could connect to a game server to obtain that functionality. In some implementations, the game is locally played without an intervening network.
