Eric B et al.; have you found a "optimum" ratio of science/gold/culture/religious cities? I know you said you typically have but one culture based cities. What about the other types? I never thought of this solution before, and I think it will solve many of the problems I've been experiencing in my higher difficulty setting games. I've been trying to make EVERY city, the perfect city. Rather than allowing each city to be good at one particular facet of the overall society. Do you tend to have any cities which are "jacks of all trades" so to speak?
