You should add a way to sell elemental cores! I currently have 26 of them, and that's way more than I'll ever need at any one time. They would probably be pretty expensive, which would be great. It would provide a huge source of credits and gems for when we need it. Earlier today I lost like half of my ship and the same happened to my brother (actually it was more like the back of our ships but still). In a time like that, it would have really come in handy a good way to get lots of money easily for repairs.
