A mechanism is provided for configuring offline player behavior within a persistent world game. A player agent for an offline player includes an event monitor that monitors for events that occur in a persistent virtual world maintained by a game server. When a game event occurs that triggers an offline player rule, the player agent may generate game events on behalf of the offline player. The player agent may also receive messages from an offline player. The messages may include commands for adding, removing, or editing offline player rules. A message may also include a command to view a list of rules or fire a one-time execution of a rule upon receipt. Therefore, a player may contribute to the persistent virtual world even when offline by sending commands using a messaging client or Web browser.
