Time for an old classic game: Moon-buggyMoon-buggy by Jochen Voss, based on the even older Moon Patrol, which celebrates its 30th birthday his year.
I remember installing the command line game on my Sun SPARCstation 1 computer at university many moons ago. Hours of fun! Well, waisted time actually. Never-mind, I am delighted to have found it again. You can't beat command line games. One day I shall try to control the moon buggy with my Arduino.
