AI agent multiplayer opponent

[robotlincoln]

Just curious if anyone's experimented with making and training an AI agent to play in multiplayer games in the place of the game's AI opponent. I know that people have done versions of this for Skyrim. This is really outside my wheelhouse, but it seems like a challenging and unpredictable AI--especially one that you could chat with as a form of diplomacy--would breathe a lot of life into the game.
