Not sure where to post this.
Not exactly a city building game, but I'm doing just that.
An old skyline shot.
Yes, I have some time on my hands. There are four subway stations around the park (they are underground), so I plan on really expanding the city. I can just put buildings over top of rides (except coasters). It's quite hard to create variety in the buildings as the selection of wall styles is very limited (it is, of course a theme park game, not a city building game).
