In Cities: Skylines the development of a city is simulated, taking into account various factors such as crime, environment, taxes, traffic flow and education.

There are two types of workplaces: industrial and office. Additionally, the user can designate other districts, for example, to encourage the oil or agricultural industries. The look of the city or district changes depending on the settings specified.

Straight roads are possible, as are irregularly shaped roads. The network for the various zones is based on the street's path. Different street types (avenues, for example) and street widths (from dirt roads to highways) have varying effects on property values and noise pollution.
Along with roads, the player may construct bus, subway, and railway lines, cruise and cargo ports, passenger and cargo airports, and, with the help of numerous addons, tram, trolleybus, monorail, cable car, and ferry lines, taxi stands, and zeppelin and helicopter terminals. With the asset or map editor, you may modify current assets or create your own to use in the game. This enables the simulation of real-world towns and landscapes. [Wikipedia]
