Cities: Skylines is a single-player city-building simulation game. Players manage all aspects of a growing city including zoning residential, commercial, and industrial areas, constructing infrastructure such as roads, public transit, and utilities, and balancing budgets through taxation and services. The game features a transport system, modding support through the Steam Workshop, and a progression system that unlocks new buildings and services as the city's population grows.
