I started my first game on king and am amazed by how easy it is to come by era score. King. Standard speed. Standard map size. 8 civs. Normal city states. I shed as Zulu. Does it become harder to get era points as you climb difficulty? It seems that EVERYTHING gives points. I found I didn't have to pay attention to my score at all to achieve golden ages. As a way of scaling difficulty within the game it would make sense to me that you get less points for things as you increase your level.
