In one of Brad's recent gameplay examples, he plays on a Total War map against the Drengin and they are at "Permanent War".
I didn't see the "Permanent War" option in the game setup. Is there a way to setup a game with say, a small map against 1 AI and be at "Permanent War". I'm thinking this would solve the problem of the AIs trading all their techs to each other at the Intelligent level.
Or maybe if you just pick one AI as an opponent, it automatically defaults to "Permanent War"?
