Methods for managing non-player characters and power centers in a computer game are based on character hierarchies and individualized correspondences between each character's traits or rank and events that involve other non-player characters or objects. Players may share power centers, character hierarchies, non-player characters, and related quests involving the shared objects with other players playing separate and unrelated game instances over a computer network, with the outcome of the quests reflected in different the games. Various configurations of game machines are used to implement the methods.
