I’m pretty sure you could train an AI to play a game like Civ, but the problem stays the same. As everything progresses to get more complicated and you have to decide even more every turn it gets harder and harder to train. The results are kind of unpredictable and you might have to train your AI again with every patch. It will limit the systems your game can run on (even excluding some platforms) and heavily impact performance on the systems it can run on.
