Imagine that your spaceship just crash-landed on a strange planet. You don’t know where you are and how to reach out to Earth. But luckily, there is a lot of scrap left from the catastrophe, and this whole planet is an untapped pool of materials, all kinds of them. And you just happen to be a mechanic! Now it’s up to you to provide yourself with all kinds of equipment and machinery not only to survive, but actually to lead a rather comfortable lifestyle thousands light years away from home. Good luck!
