So, I'm mid way into the game and have four cities. One for production, one for science and two for gold. My science and my gold city have their university and bank. My army is large enough and upgraded to the maximum. I have enought happy citizens. So, what do you build next? Just make them produce gold/beaker? Or try to cross and also create banks in the science city etc? Finally, I feel that I can end any game before Renaissance only by warmongering. Is it because I am playing in a lvl too low (currently King) or will it change?
