If you are longing for a proper city building game but cannot stand the many of such games in the genre that are developed under the fremium model, Pocket City may be what you are looking for, as it is a full-fledged premium title.
As with most other city builders, you take on the role of a new mayor who is entrusted with building the city. You will have to lay out the necessary residential, commercial, and industrial zones as you see fit. Of course, you are required to manage the many other aspects that make a city livable, such as crime and pollution.
If you are familiar with games such as Sim City and Cities Skyline, Pocket City is essentially all that but for the mobile platform. Fans of the genre will definitely want to keep an eye out for this game.
