First of all, a player market where players can trade should be added to each trading post. This market, when clicked on, would show a menu of a list of most popular offerings. Players could offer resources such as gems /element cores, and they could either put a price on what theyre offering with what they want, or people could send their own offers to what they offered and both can bargain it out. This would allow us to trade tings like mined parts or gems. WE could even sell used parts on ships if the devs were nice.
