Minetest
Minetest is a free and open-source sandbox video game and game creation system with focus on voxel graphics. It is written primarily in C++ and makes use of the Irrlicht Engine. Minetest provides an API for users to write their own games and mods written in Lua. It is cross-platform, being available for Linux-based systems, FreeBSD, Microsoft Windows, MacOS, and Android. In the default game of Minetest, Minetest Game (MTG for short), players explore a blocky, procedurally-generated 3D world spanning approximately 31 000 full nodes (blocks) in each direction, and may discover and extract raw materials, craft tools and items, and build structures and landscapes. Depending on the game selected and mods present, players can fight computer-controlled "mobs", as well as cooperate with or compete against other players in the same world. The game mechanics of Minetest are similar to those of the 2009 game Minecraft. Over a decade of active development Minetest has garnered critical acclaim and gained in popularity; since November 2013 Minetest has been downloaded over 1.4 million times from GitHub, and the Android version of Minetest has over 500,000 downloads on the Google Play store.
