Minetest is an open-source game engine which allows easy creation of Minecraft-like games. Minetest has over 100 million downloads across all our ports and third-party clients, 340 contributors, and stable development. We've recently released Minetest 5.0.0, which greatly improves the ability of the API. Coming soon, 5.1.0 will allow better GUIs and more.
