Game needs a campaign, once the initial novelty of building a tiny little city is gone the fun wears off. Needs something to keep challenging you and showing off the finer points of the game. As is it's just a tool set with little people running around that have no real purpose in the game.
The bottom line is this is not city building it's small town building to equal a big city once it is combined with other towns. The plots are just not large enough to provide a deep gameplay experience. You just find yourself doing the same thing over and over again.
