You can craft stuff, upgrade weapons and space suits. Lots of things are just crap to sell, and here’s a thing I enjoy doing: I find a mission asking me to kill a pirate in a ship somewhere, go there, “convince” them to let me in their ship, then I “negotiate” a transfer of ownership. I land somewhere I can buy and sell ships, sell my new acquisition. ALL THE CRAP it had gets moved into my ship. I go sell dozens of note pads, singular playing cards, half eaten sandwiches and so on, all nearly worthless stuff but it adds up lol
