I initially thought the coins on the working tiles corresponded to money that goes to treasury (a.k.a. tax money)... but that doesn't seem to be the case; they go to science/culture/wealth. So I was wondering, what determines the tax money you make? I could understand that improvements like markets and banks give a % boost to this tax money... but where does the base money come from? I could think of trade routes, and founding of a religion (+1 per city spread).. but what else? Since I can't seem to found a religion in a city of my choice, all I can do to specialize, AFAIK, is have as many trade routes as possible... Why can't I choose which city to found it in, anyway? I *HATE* seeing it found in my military production city, for example.
