Citybound is an open-source, one-man-developed city-building game that simulates urban life at a microscopic level, modeling millions of individual inhabitants and their interactions.

Why it matters: It offers unprecedented realism by simulating every household, trip, and trade interaction, creating dynamic city evolution.

The big picture: Combines advanced microeconomic, transport, and actor-based distributed simulations to scale cities with millions of inhabitants in real time.

Future potential: Plans include pedestrian and multi-modal transport, collaborative multiplayer planning, and 3D features like bridges and tunnels.

Commenters say: Enthusiasts praise the deep simulation and technical ambition, while discussing challenges of performance, complexity, and scalability.
