I'm been analyzing all the different civilization and I have some suggestions regarding the better path of victory, based in bonus and tech that each civilization has. American: Economy, because of the 2% bonus at the beginning and the extra production during the Modern era make them very good to reach the World Bank before anyone. Domination: Easy to understand why. 1/2 price rushing units and the bonus inf factories make America a machine creating units in no time. Arabs: Economic, because of the 50% bonus for caravans + 2% interest on gold during the Modern era. Domination, Mathematics for free on Medieval era make them a powerful civilization specially because the have since the beginning of the game the Fundamentalism and that + cataputs... = GG. Aztecs: Economic, 25 gold at the beginning and 50% gold production is a huge bonus. Domination, Heal automatically after winning a fight? Are you kidding me?. Chinese: Technology, Knowing Writing at the beginning is a huge step forward in the technology victory, they can reach the university of oxford very fast and that could give them a advantage in tech against any other civilization. More to come soon. ALL THIS IS IMO, so please collaborate if you have any other idea.
