Minecraft was created by Markus 'Notch' Person, a Swedish developer. It has sold over 11.5 million copies, making it the 5th most downloaded game. The game allows players to build structures in randomly generated worlds that are larger than the planet Neptune. Within the game players can encounter creatures like the Enderman and Creeper. People have used the game for massive building projects recreating places like King's Landing from Game of Thrones.
