OpenCiv3 is an open-source, cross-platform reimagining of Civilization III, built by the fan community using the Godot Engine and C#. The project aims to modernize the game, removing arbitrary limits, fixing broken features, and supporting modern graphics and platforms. OpenCiv3 is currently in an early pre-alpha state and is available for download on GitHub. The game can be played in standalone mode or with imported Civ3 graphics.
