Minetest

Minetest is an open source construction game, and an endless adventure in a world entirely made of cubes. Yes, just like Minecraft.

Minetest have been developing since 2010 like an open source project, where many users have collaborated to create a free game of this kind. Withouth no doubt, Minetest is the best choice for those who want to enjoy a game like Minecraft for free. You can have many of the Mojang's title features, like build anything that you want or survive while we interact with the environment.

Furthermore, as an open source game we can freely dispose of his API, and modify this way any aspect of the game. Minetest also includes multiplayer gamemode, and is designed to be lightweight and run in most computers. Its the best option is Minecraft Java issues makes Mojang's game impossible to play for you.

You will be able to do many things that you would do in Minecraft: house building, cave exploring... and improve the game's graphics with custom texture packs.

Obviously it not offers as many secrets and features like Minecraft (a game with millions of copies sold) but we can be grateful for this free alternative for a game like this.
