CONTROLLING A MASSIVELY MULTIPLAYER ONLINE ROLE-PLAYING GAME

Briefly stated, technologies are generally described for controlling a massively multiplayer online role-playing game (MMORPG), using a user-interface (UI) selection unit, an action log unit, a pattern detector unit and/or an artificial intelligence (AI) player unit. In various examples, a system is described, where the system may be configured to control the action log unit to record logs of a user's actions input through a UI and associate the actions with status information of the user's character and opponent characters in the MMORPG. The system may control the pattern detector unit to extract correlation rules for the status information and the associated actions. The AI player unit may control a substitute player for the user based on the correlation rules, such that the substitute player can automatically reproduce actions of the user.
