And I am just playing on Prince In a standard size map when I have the same amount of cities as the AI, I for most of the time will be DoW by an AI at early-mid medieval time when it rushes me with stacks of 15+ units. At that stage of the game, I will only have 3-4 units per city and research at 60% when I can barely keep up with the others in research. Needless to say I am in no position to defend myself. When I enter the World Builder and check my opponent, it tends to have 4 units per city defending plus the 2 stacks of 15+ units. This raises the question for me - how on earth does it afford these many units? Admittedly I have been building buildings here and there and slacking off in units building, but with that many units how does the AI keep up with the tech race?
