In my latest Immortal game (not sure why I don't just go to Deity again), there have been many promising aspects of the AI (expansion rate, science rate, district selection...), but there seems to be zero, or even negative priority on building/keeping units. Early on, this is not an issue. They build and keep a decent army and pose a reasonable threat. But as the game progresses it is almost like they refuse to maintain an army and disband or never re-build units lost in battle. A case in point is China in my current game: I had a war with them in the classical era that ended in stalemate. Many eras later when I considered attacking them due to their nice cities and lead in science, I hovered over their icon in the world rankings panel to find "Military Strength: 0" under their icon. Zero!? Sure enough, I invaded and there was absolutely nothing. This is after centuries of peace; they didn't go to war with anyone else and were in second place in science compared to seven total civilizations. Has anyone found a MOD or anything to get the AI to maintain an army? The AI seem to be better at using units in the latest patch, but refuses to actually have an army. If I could find a way for units to be almost 'free' for the AI, maybe they would build them and actually play the game?
