O-kay, you asked for it
Granted! You are the first man to be sent to Mars, in an attempt to colonise the planet. But sadly, when you reach the planet, your ship malfunctions and you crash land. You lose radio contact with Earth, and most of you colonizing supplys are destroyed. However you have life-support...and Jimmy Hendrix's guitar you were given, because you asked so nicely. So you are on Mars. Just you. Playing the guitar. With the mad skill of Jimmy Hendrix (you had time to practise). No surprises. No rescue team either.... Just you and the guitar.
I wish the aliens would come, and give us cool techs.
