    Cities: Skylines is a city-building simulation game developed by Colossal Order and published by Paradox Interactive for the PC, Mac, and Linux on March 10th, 2015.

    From the Finnish studio behind the Cities in Motion series of public transport management games, Cities: Skylines tasks players with building-up and managing their own city through urban planning and development (similar to the SimCity series). It includes a non-orthogonal grid system, a standard RCI zoning system (with separate governmental buildings), unlockable city improvements, a districting system (which can be used for regulating things such as traffic and commerce), and robust road-building, traffic, and transportation systems.

    Along with a comprehensive modding system (via Steam Workshop), the game received numerous expansions and updates since its original release, adding a variety of new gameplay features (such as a day-night cycle, alternate visual themes, in-game radio system, natural disasters, new public transit options, and new zoning options).

    It was later ported by Tantalus Media for the Xbox One on April 21, 2017, the PlayStation 4 on August 15, 2017, and the Nintendo Switch on September 13, 2018. The XONE and PS4 versions also received a physical release by KOCH Media.


    Cities: Skylines is heavily inspired by the SimCity model, with RCI zoning, a focus on civic infrastructure, and little to no resource chain management. The game uses an agent-based simulation system similar to SimCity (2013), but with smarter citizens that remember their own home and workplace. Colossal Order has stated there will be a limit of 1 million citizens, each with a home, job, education and many other parameters. This limit may be increased in the future, or be opened to modification. Citizens will take multiple transportation options, with a preference towards public transportation where available. However, timed traffic is not simulated, as the days pass too fast to have an internal day / night cycle.

    Cities: Skylines also features a unlock system, where new buildings, infrastructure, and services unlock when your city reaches a population threshold. Players start with simple roads, but can quickly progress to avenues and highways as the city grows. However, players can also disable it and start with everything unlocked via Sandbox mode.

    Maps start at a single 4km² tile, but new map tiles can be bought in game, bringing it to a non-modded maximum of 9 tiles in any direction. This can be further expanded via modding to a theoretical maximum of 25 tiles, or 100km². Maps cannot be terraformed once in game due to the water simulation.

    Expansions and DLC

    Expansion Packs

    After Dark

    Cities: Skylines' first paid DLC was released on September 24th, 2015. Entitled 'After Dark', the expansion pack adds new city services, a leisure and tourism city specialisation and a day and night cycle. The day and night cycle was also added to the core game, making it available to all players, whether they own the DLC or not, although some related functionality is only available to owners of the DLC.


    No Caption Provided

    'Snowfall', Cities: Skylines' second paid DLC, was released February 18th, 2016. It introduces new transport options to the game, including trams, as well as a dynamic weather system including rain, fog and snow. In addition to aesthetic effects, weather also impacts the behavior of citizens; Cold weather will bring increased power usage and snow will cause traffic problems for the player to contend with.

    Natural Disasters

    The third major DLC released for Cities: Skylines is 'Natural Disasters'. Released on November 29th, 2016, it introduces new gameplay focused around catastrophic events that can impact the player's city including earthquakes, thunderstorms, tsunamis, forest fires, tornadoes, sinkholes and meteors. New scenarios require the player to plan-for and respond-to these events using tools such as early warning systems, emergency vehicle routes and evacuations.

    Mass Transit

    Cities: Skylines' fourth major DLC pack, 'Mass Transit', was released on May 18th, 2017. It allows players to add several new public transport options to their cities including blimps, ferries, cable cars and monorails. It also introduces several new road types and new mass transit hubs, where citizens can transfer from one type of mass transit to another. Alongside the paid DLC, a free update was released for all players that adds several transit-related features, such as the ability to name roads, one-way train track and the ability to customise stop signs and traffic lights at junctions.

Colossal Order actively encourages modding, and will try to open up the game as much as possible to modders.
