A method and system tracks, analyzes or sorts behaviors of user or players across a network to draw correlations from, or characterizations of, those user or players and identifies similarly characterized or mutually complementary user or players. For example, the method automatically obtains player data regarding interactions by each of multiple players with a multiplayer electronic game via each player's corresponding data processing device connected via the network. The method can then sort, classify or suggest additional activities, games, groups, or other different activities or actions for the players.
