New on Steam: This management sim lets players recreate real-world subway systems using census data

Subway Builder has launched on Steam. The management game allows players to create their own subway networks in select cities and show urban planners what could be possible. Real population data serves as the foundation for the simulation. It is still only a game, of course, but it could nevertheless convey some basic insights into the potential of public transit, much like games such as Transport Fever can provide a better understanding of rail infrastructure and capacity.

Subway Builder does not simply rely on the population density of its supported cities. Its simulation utilizes real data that account for both where people live and where they work, resulting in realistic commuter traffic. Income statistics and other data points also influence how likely residents in a particular area are to use public transit. The simulation also accounts for college students, a category roughly comparable to students at universities of applied sciences or vocational colleges in Germany. They also need to travel to their educational institutions.

FAA data is used to simulate airline passengers traveling within a city, whether they are heading to or leaving the airport. This should quickly provide a sense of how each city functions. Subway Builder currently focuses primarily on the US, with more than 30 cities available. Los Angeles was also expected to arrive with the Steam release, according to an announcement by the developer on social media. Several cities in the UK are included as well, although coverage is currently limited to England.

The game is now available on Steam for $40, which makes it $10 more expensive than on the official website. According to the developer, the difference covers Steam's cut for providing the platform infrastructure. Windows, macOS, and Linux are supported, while Chromebooks are explicitly excluded. The system requirements are modest, with only around 1GB of storage needed and 8GB of RAM recommended.

Development will continue after launch, with additional features planned. The official roadmap provides an overview of what is coming.
