The LEGO Minecraft theme is based on the video game Minecraft and a collaboration between Mojang and the LEGO Group. Minecraft is a sandbox indie game originally created by Swedish programmer Notch (Markus Persson) and later developed and published by Mojang / Microsoft. The official release occurred in 2013 with the first set, Minecraft: Micro World: The Forest, released under LEGO Ideas and was created by Mojang through the Lego CUUSOO program in 2012. At MineCon 2013, LEGO announced brand new minifigure-scale Minecraft sets.
