Minecraft is a sandbox-building independent video game written in Java originally by Swedish creator Markus "Notch" Persson and now by his company, Mojang, formed from the proceeds of the game. It was released as an alpha on May 17, 2009, with a beta version on December 20, 2010. Official releases for iOS and Android have been released and the full version of the PC game was released on November 18, 2011 at MineCon 2011. The Android release was temporarily exclusive to the Xperia Play but is now available to the rest of the Android market. A version of the game for the Xbox 360 with Kinect support is under development by 4J Studios and delayed until 2012.
Minecraft is focused on creativity and building, allowing players to build constructions out of textured cubes in a 3D world. Gameplay in its commercial release has two principal modes: Survival, which requires players to acquire resources themselves and maintain their health and hunger; and Creative, where the player has an unlimited supply of resources, the ability to fly, and no concept of health or hunger. A third gameplay mode, named Hardcore, ratchets up the difficulty of surviving and forces the player to delete his or her world upon death. An outdated Classic version is also available for free, although it is no longer being developed. Creative Minecraft resembles Classic, but with many more features.
The game was officially released at MineCon on November 18, 2011. Minecraft was developed for about a week before its public release on May 17, 2009, on the TIGSource forums, where it gained a considerable level of popularity. It has been continually updated and patched since then, and while it was still in alpha release, it garnered several hundred thousand sales and received critical notice and acclaim from many reviewers. It passed a million units sold on January 12, 2011, less than a month after reaching Beta. By November 7, 2011, the game had sold 4 million units. Thank you wiki for the artical.
