I think at least 2/3 of civilization is ultimately about economics. Assuming expensive units and city improvements, no incremental rush buying, essentially vanilla terrain resource values and moderately lucrative potential for trade should the optimal strategy for maximizing production favor massing trade units and rushbuying or maintaining production improvements like the factory or mfg. plant? What sorts of trade offs are there, are there any increasing or decreasing returns to scale? I know that this question can hugely affect players overall strategy, so from a balancing point of view I wonder what you guys all think: factories or caravans?
