I loved sim city when I was a kid. The game is set up so you have no incentive to zone low density, not too much like the real world where it would get you thrown out of office to zone everything high density.

China needs to build like crazy as it is in the process of moving a billion peasants into urban areas. Prices are also much more out of whack than any other large economy compared to either rents or income. Lots of condos sell for 50x annual rent or more.

That is another reason in addition to freedom, stability and pollution to get out of China. Urban condos are priced higher than in major west coast cities but incomes are still a fraction of US incomes.
