So as a new player I am learning how to best specialize cities. I am a little unclear on the how to avoid wasteful builds when it comes to national wonders that require some number of another building. Had a few questions on the topic: 1) Should I try to build all national (obviously not world) wonders each game, or only when circumstances point me there? For example, Wall Street requires 6 banks in standard size maps. Most people seem to suggest nowadays you will have 1 gold generating city. Does that mean I should just accept I need to “waste” the time to make 5 banks in low gold cities to get Wall Street? Should I just knock these out in generally high commerce cities even if I’m, say, 70% science slider? Alternatively, should I only build Wall Street when I get a profitable holy city, corporation, etc? Same is somewhat true of Oxford, but it is more feasible to me to have 6 cities with decent commerce or specialists to make 6 universities worth building. 2) When I make a cottage city, do I want to build beaker% buildings, gold%, or both? My intuition is that I’d want to do whichever I’ll have more commerce into (hopefully beakers), but this fluctuates over the course of the game. 3) Is there any math or otherwise suggesting if building wealth or research in cities is better? 4) Is it common to build something like a grocer or market just for the health or happy bonus, even if the gold% bonus is totally wasted?
