A good way to spend time, but way more similar to a zynga game, where you need experience to get you to another level and unlock buildings, then a real sim city that gives you more information.
This game will, most of the time, just give you the difference between jobs available and citizens.
Another good thing is that you dont need internet connection to play. You can play anywhere!
Definitely recommend!
