In Callisto, you're a former military officer who is now trying to make a living by trading and scavenging in space. Your ship is called the Callisto, and you have a ragtag crew who are battle-tested through and through. You experience new adventures, and there are also plenty of opportunities to form relationships along your travels. It's not the easiest way to earn a living, but at least you don't have to do the daily grind of working a nine-to-five job.
