Minecraft has been playable on a PC for quite some time but recently the game made its way to phones and Xbox 360.  The name of the game essentially says it all, you mine to get supplies and them craft stuff out of the supplies.  Everything in the game is cubes, which makes building things that are circular a challenge.  While playing the game you can either join online severs with other people or create you own world.  The created world is a flat surface that randomly generates as players walk further from the spawn location.  Within the world of Minecraft there are many monsters that will come out at night if you are not in peaceful mode.  Probably the most known of these monsters are creepers which will explode if they get close enough to a player.  If you are lazy you can play creative mode instead of survival in which there is no need to collect materials you already have unlimited everything.  Overall Minecraft is cheap compared to other games and is worth every penny.  Many of times I have went back to playing after getting bored with other games.
