Good, good, that's it.
Gameplay wise, i think if your a city building sim, this would only last for you around 3 days (non-continous playing), as i think the initial impression is the thing that's good. Though as with other games that look good, the look could only take it to some degree. Gameplay will also be kinda monotonous, though the problems of the city will kinda make things different every time.
The game is good for passing the time, though it's not in my A-list games, but the thing still plays good.
