Minetest-Classic is a fork of Minetest-C55, an infinite-world block sandbox game and a game engine, inspired by InfiniMiner, Minecraft and the like. It aims to improve speed, fix bugs, and add features and functionality. The game includes over 400 blocks, craft items, and tools, in both functional and decorative types. Minetest-Classic has a focus on immersive gameplay where in-world mechanisms are preferred over special commands, such as using incinerators instead of a /pulverise command, or craft guides being implemented as part of the in-game book system, rather than as a special menu item. In addition to single player mode, online multi-player is also available.
