[Idea] AI Personalities
I was thinking it would be cool if the AI had a third setting(or replaced the difficulty setting) that described how it behaved like cautious, forgetful, careless or analytical. This idea is roughly based how the Worms series handles their AI. I don't believe an AI has to be rational or efficient to be fun. For example, lets say the cautious AI builds gauss platforms before it builds anything else or it always keeps ships at its capital(even if it isn't remotely threatened).
I think it would take out the guess work out of trying to figure out what type of behavior an AI has other than the "hard" or "easy" settings. For example, lets say a player cannot tolerate how the Careless AI never retreats from battle. That player probably won't select the Careless AI. Therefore, a player can better tailor each game to their liking.
Plus it would also add variety.
