Well I didn't like it. Didn't hate it like I did Cities XXL which was just an unfinished product with hardly any game in there, this one in comparison is great at what it does... but for some reason, I don't see the point.
I must admit I am not the most creative type, so just building to be able to build amazing highway systems is not really what I'm looking for. I need a game, and for me, SimCity, yes also the latest one, is the only one that provides that.
Skylines gives you a very limited amount of bonus buildings based on different parameters, but what I love in SimCity is the engine builidng and goods production/shipping, like you have to desing a chain of production facilities to make electronics, then you can ship them for mad cash. And you have to do that, because you'll run out of money otherwise. XXL, and in a lesser way, Skylines, are just about drawing grid after grid after grid, money just pours in, and esthetics are the only thing you have to worry about. Skylines has the districts thing, but yeah... no.
Maybe I'm missing something, and maybe I'll give it another whirl some day, but as is I burnt out on this on a single afternoon.
