A city-building game, or town-building game, is a genre of simulation video game where players act as the overall planner and leader of a city or town, looking down on it from above, and being responsible for its growth and management strategy.

City building games are a popular genre of strategy games that allow players to create and manage their own virtual cities. These games provide a sandbox-like experience where players have the freedom to design and construct their ideal city, making decisions on various aspects of urban development, resource management, and citizen happiness.
