Minecraft
The sandbox game that millions enjoy today!
Minecraft is an indie game that millions bought, and play. This is also available on the X Box, and even mobile devices.
The PC version is really the ultimate version though. Play with friends, build enormous skyscrapers, even make your own roller coaster as a part of a humongous Amusement Park. Explore caves and ravines, climb mountains in the falling snow. This game has it all.
Get it all!
