Luanti

Luanti (formerly known as Minetest) is a community-driven, free and open-source voxel game engine, available on various platforms. Originally, Minetest was a voxel game created in October 2010 by Perttu Ahola to explore the mechanics of Minecraft. Over time, Luanti evolved from the original Minetest game into a general game engine as developers integrated new features. Luanti allows for the creation, development, and customization of games and modules (shortened to mods) using its Lua scripting system. Games are collections of mods that together establish a complete gameplay experience (by defining major content and behavior), while individual mods serve to modify or complement specific features within games, and may be added, replaced, or removed by players to customize them. To download games and mods, Luanti provides a built-in browser to access ContentDB, through which they can be installed. Despite its origins, the community considers Luanti a game engine rather than a singular game, as it no longer offers any playable content without third-party games and mods. Luanti itself is based on the Irrlicht engine. Luanti's name is a portmanteau formed from Lua (the scripting language) and the Finnish word luonti, meaning "creation".
