Been testing this mod collection now, and changing a few mods. So far, the combination AI Booster, AI Builder Booster, Real Strategy and April AI Science reverted seems to function quite well. See pictures for the aggressive AI player Gilgamesh and AI Scythia attacking and taking cities from Mongolia, e.g. their capital city. Using Better Spectator Mod and "No World Congress" (since World Congress seems to stop the spectator mod from working) to simulate AI vs AI encounters.
