The size of the world within the game Minecraft measures 39.5 billion square miles, larger than the planet Neptune at roughly 2.94 billion square miles, and much larger than Earth, which measures only 196.7 million square miles. This gives players practically unlimited room for expansion in this role-playing video game, which allows players complete freedom to build their own virtual worlds one block at a time.
To give an idea of this massive size, estimates of the size of just one block range from 2-1/2 to 3 feet tall based on the average height of the Minecraft characters. The entire Minecraft world can hold a little more than one quadrillion of these building blocks.
In the world of video games sales and popularity, Minecraft's popularity is comparatively massive. The game, released in 2009, has sold more than 50 million copies, with a $1,500,000,000 investment from Microsoft in September of 2014 to further expand the game.
