It's probably natural to pick the best cities for these example, like my NE-NP city above, but it's a good point to consider that perhaps that makes it difficult to relate to for other readers, because the cities are already so absurdly good.
The city I showed an image of, btw, was not my own city, it was a captured one from an early war against India. But it is on the Rainforest mapscript, which has lots and lots of food, but almost every tile is covered in jungle, so you need ample time to cut it down with heaps of workers. Cities like that is exceedingly rare on more normal mapscripts like Pangaea, Fractal, Terra.
