OpenCity is an open-source city simulation game that offers players a chance to design and manage their own urban environments in 3D. Inspired by classic city-building games, it allows users to start with three distinct plot types: residential, commercial, or industrial. Players must navigate various factors such as road accessibility and electricity supply to develop each zone effectively. The game features randomly generated landscapes, adding a layer of unpredictability to city planning.

In addition to constructing buildings, players are tasked with establishing essential services, including power plants, police stations, sanitation, and fire departments, to ensure the well-being of their citizens. While OpenCity is currently in its preliminary phase, it shows promise for future enhancements, making it an engaging option for simulation enthusiasts and aspiring city planners.
