City Builder Starter Kit announcement

MonoGame Foundation has launched early access for a City Builder Starter Kit, positioning it as a practical 3D example for developers learning or prototyping with MonoGame. The project is a straight port of Kenney’s original Godot 4.5 city-builder demo, with the same assets carried over into the MonoGame version.

The kit covers the core systems you’d expect in a small city builder: building and removing structures on a grid, smooth pan/rotate/zoom camera controls, structure rotation and cycling, drag-to-place and drag-to-delete behavior, and save/load support with a bundled sample city. It also includes a main menu that orbits the sample city, a pause menu, and a centralized input manager designed around keyboard and mouse first, but ready for gamepad support.

For teams working in MonoGame, the value here is less about a finished game and more about a reference implementation that shows how to structure a 3D project cleanly. The sample uses CC0 sprites, 3D models, and sound effects, which makes it easier to study, modify, and reuse without asset licensing friction.

Access is currently limited to contributors at the SpriteBatch tier or above through GitHub, Patreon, or PayPal. The Foundation says the kit will be released publicly once the solution is complete, and early supporters get source access, Discord discussion, and a chance to help shape the final version.
