A ways back, I had found this web site that broke down, in hard numbers, the relationship between a regions population and the size of your buildings.
It was a table that looked something like this:
Region Population Size 1 - %
Size 2 - %
Size 3 - %
and so on.
It would have been, if I hadn’t gone on to lose the bookmark. Anybody know where the web site is, or what the stage limits are?
