Oh that might be it then. By the time I get to Military Science I have scouted most of the world, small map things. So maybe
I can sell
them the map? Never tried actually. But I never give things to the AI, like embassies and open borders. Well when the world congress is founded I do trade embassies since all capitals are revealed by it and sometimes technologies if I need the money. Can showing them my map somehow hurt me?
Unrelated, but can someone explain to me how does the AI have a flat +30% combat bonus on their units? Where is that coming from? Their promotions looked pretty regular, and while they had Authority no one had Autocracy. Some embarked units had +60%, but that wasn't as relevant since they were still easy to sink with boats and bombers. Luckily also the AI was very unhappy so it evened out, otherwise my two front war would have gone
much worse.
