Minecraft is the brainchild of Markus "Notch" Persson and is a game about placing blocks while running from skeletons and other enemies. The game has become quite a phenomenon and has grown in popularity with players. The game consists mainly of crafting and acquisition while avoiding things that want to bring you harm. While the mojo that makes this game so popular isn't quite understood even by some of its players, MineCraft has managed to latch on and draw players in. A massive community formed around the game even before its official launch with players creating everything from a full version of Middle-earth to a number of other massive and impressive projects.
Minecraft has brought together a very creative community that is capable of doing some amazing things with such a simple game. Minecraft can be purchased via the official website for a one-time fee.
