Minecraft is a sandbox video game originally created by Swedish game designer Markus “Notch” Persson, and later developed and published by Mojang. The creative and building aspects of Minecraft enable players to build constructions out of textured cubes in a 3D procedurally generated world. Other activities in the game include exploration, resource gathering, crafting, and combat. Multiple gameplay modes are available, including survival mode where the player must acquire resources to build the world and maintain health, a creative mode where players have unlimited resources to build with and the ability to fly, an adventure mode where players can play custom maps created by other players, and a spectator mode where players can fly around and clip through blocks, but cannot place or destroy any. The PC version of the game is noted for its modding scene, where a dedicated community creates new gameplay mechanics, items, and assets for the game.
Minecraft received praise from critics upon release, and won numerous awards and accolades. As of June 2016, over 106 million copies have been sold across all platforms, with more than 40 million unique players each month, making it the best-selling PC game to date and the second best-selling video game of all time, only behind the various releases of Tetris. In September 2014, Microsoft announced a deal to buy Mojang and the Minecraft intellectual property for US$2.5 billion, with the acquisition being completed two months later.
