concepts for a new aspect
Basically I was thinking about how you have a certain number of people on you ship that don't help with anything except capturing other ships. So I devised a few ideas for having crew slots in your ship. Then have a few required crew members that you automatically get with your ship, but you can hire other crew for bonuses. Such as a weapon's expert that would give your weapons a rate-of-fire boost. Or a navigations expert who will give you energy boosts. Or engineers that will repair your armor over time.
Then on a small run off of this concept you could even have apprentices that pay you for teaching them how to work on a ship. They'd pay you money over a period of time for teaching them. Though they would remain less effective until they learned how to properly work equipment. So they would have a temporary handicap on your ship while they provide you with money in the long run.
