Just a warning that although it claims to support Linux, on launch I got two options:

* Run without wine (Linux)

* Launch with wine

The first one took me to a black screen. The second took me into the game but the colors were entirely wrong -- everything was red and black. So caveat emptor.

It's really good! I like that the zoning is more realistic and the finances seem to make more sense (e.g. when you hit $0 cash you start borrowing automatically, rather than having to explicitly take out a loan, and also you have to pay emminent domain when you destroy someone's building). Also the regional scale is neat.
