I think the main problem with city story is that it's too hard to make money. You get a mere twenty coins for cleaning, but other than that, none of your buildings are profitable. And if you actually want to make your city look nice, you have to use precious space to build roads and parks and things which don't make any money at all. I think that the solution to this problem is twofold. First, make all businesses not just factories, earn money, and make it possible to clean roads and other decorations. Also, by nature a city needs to be bigger than a farm, so you should make it cheaper to expand. A price increase of 100k for every expansion is much too steep. If you made those simple changes, I think City Storybwoild be much more interesting to play.
