Is there a way to keep up with the AI when it comes to empire expansion? I am playing on Regent level on a huge map with four other Civs. I can pop a settler every 7 turns in my capitol city. But even at that rate the AI has twice as many citys as I do. Right now I am sending all my settlers out to the fringes of my empire to hold off the AI expanding into my area. This is giving me a lot of corrupt cites in my early game. I think I have only got two solutions to my problem. Use OCP around my capitol to develop a small but larger civ, or instead of building settlers, build warriors and attack the AI ASAP. Right now all the citys they have are 1 and 2 population jobs. This is my current game. I am playing as the Persians on a Pangea with China, Ottomans, Zulu, Arabs and Babylonians. China is my current problem. I have not made contact yet with any of the other Civs. So my question is what is the best way to deal with AI expansion?
