Release Date: October 9, 2025 Early Access
A realistic strategy simulation that allows players to design and construct subway lines beneath various American cities. Subway Builder can simulate the behavior of millions of passengers. Players must use this data effectively when planning metro line expansions to ensure the business remains profitable.
Colin Miller is a developer from New York, whose portfolio primarily includes various apps and utility tools. However, video games are not foreign to him, as evidenced by the production described here. It borders on economic strategy and simulation genres and was titled Subway Builder.
As the title suggests, Subway Builder allows us to become designers and constructors of subways. We bring our visions beneath the surface of several American cities, such as Austin, Baltimore, Chicago, Dallas, Detroit, Indianapolis, Philadelphia, San Francisco, Washington, or New York.
The game uses data collected for Miller's other projects, such as Census and Redistricter (an application for visualizing political and demographic data). Based on this data, the program realistically simulates the behavior of millions of passengers. When designing subway routes, we must consider all the needs and possibilities of the residents of a given city.
The game forces us to take into account various data in our plans, such as waiting times, transfers, tolerance for delays, or even the frequency with which trains should travel specific routes. The income distribution is also significant, serving as an indicator of which areas are worth investing in and which can be neglected.
That's not the end, as when planning routes, we must consider various issues, such as the presence of building foundations. Sometimes it's also necessary to construct a bridge or viaduct. The situation is complicated by the fact that our budget is not unlimited, so we must pay attention to real costs and constraints. The key to success is finding a balance between costs and the efficiency of a given line.
The graphic design of Subway Builder is kept in a simple, almost ascetic style. It consists of a city map, visualizations of buildings and metro lines, as well as various windows and charts.
