Initially developed by Swedish game designer Markus “Notch” Persson, Minecraft allows players to build towers and play challenges. The game, which could be played in either survival or creative mode, has received many awards from the international gaming press. An enormous variety of physical systems and machines can also be built in the Minecraft environment, taking the game far beyond its intended use as a simple entertainment platform into a flexible and creative building system for modeling real-world processes or things. Users have built entire computers, cities, and even planets out of Minecraft components.
