I notice on a lot of videos online guys are rushing (pre cuirs) with so few units. The other day I had built 17 doubly promoted HAs (barracks + stables) by 850BC and it was only enough to take out 3 of Louis 9!! cities [standard/imm/continents]. Sure that was kind of a fluky situation, but I generally find I need way more units than what I see in the videos to not rely on RND, even those vids done on Diety. Is diplo a factor I am missing? Do AIs who are pleased/friendly make less units or something?
