Hello all. I am wondering if the game requires X population to have X number of structures? Like you need 100 million people to keep 1 research lab running. Or, is the only building limitation the upkeep costs? In previous games I have played you needed to have a certain percent of workers to operate a structure, just wondering if that holds true?

Also, I have played a few games, never to completion yet, but my approval rating just seems to constantly go down hill. I can build a few more entertainment structures, or drop the tax rate, but it still seems to drop. Is there some way to keep your approval rating at a certain percent, or is it set to decline each turn automatically?

Thanks in advance...
