^ I like that idea (consider it stolen!). My players for a while were researching war records and then visiting the sites of space battles, salvaging the equipment from the derelicts, and using the parts to build Q-ships from old freighters. It became a great way to exercise little used non-combat skills. Second, it taught the players some important lessons about stealth, dealing with underworld figures, and the necessity to be on your toes all the time!
Even for my players now, salvage is a relatively easy way for them to gather materials or funds without me having to create an elaborate adventure. I usually just hint at the location of some downed spacecraft and they're off! They tell me what they are bringing, if they want help, and how they're going to find it.
