I am creating a space travel/management game. You have to reach your home planet. But your fuel is limited and the parts of your ship are the only thing you can use to buy new fuel. But selling ship parts makes you weaker. And your life depends on a strong ship ;-) You can travel to planets, they have shops, battles, or random events. I have to work on the balancing right now, so that its not totally easy as it is at the moment.
