Well, there was no GUI involved, but such man machine hybrid wars did often occur in MUDs, particularly ones with player killing and guilds. You would often have a set of alts controlled by scripts doing automated tasks like crafting iron from ingredients and selling it in town whereas meanwhile in combat you would have the mud client automatically drink health potions when low on health, auto attack when an enemy player walked in, etc.. I think World of Warcraft had a similar bot getting popular before it was banned.
