A simple game of block-based building, Minecraft has rocketed to the top of sales charts, having sold over 50 million copies across PC, consoles and mobile platforms. Starting off as an incredibly buggy alpha made by Markus “Notch” Persson, the game became huge after Mojang Studios took the game (and Notch) under their wing, having since released it for PS3, Xbox 360, PS4 and Xbox One.
