As a junk collector, you can have NPCs that want stuff, and gives you rare items in exchange. Like Locations of his friend who is looking for stuff too. Maybe special dungeon items to be located on the same planet as the NPC. Maybe these rare items can be turned into a NPC for a ultimate prize.
Good idea. At this stage I think that missions and quests would be a good addition for when players want to do something different. Having said that the modding community have already begun addressing this matter.
what if you can use the stuff you are collecting for the npc if its a weapon or a mech or a hat or somefing cool before you give it too the npc
Yes! Like something where you can sit in for a couple of hours and get really sweet items.. if they'd make a basic, there'll be a lot of potential for modders as well.
