Minecraft is actually a game created by Mojang. The game was then acquired by Microsoft and it's on a continuous development schedule. The game is all about placing blocks with different properties to create everything you can possibly imagine. The game works as a sandbox environment where the user is free to create, modify, destroy and do everything you want using a set of tools, a benchmark to create items, oven to mix ingredients, etc.
