? The only two items I kept as spoils of war are the AP blaster rifle and the scoped blaster rifle (I think I got those in the Bladesea adventures), and I've had my two heavy blaster pistols since the start of the game. Pretty well everything else I have was bought.
Considering the amount of stuff we've gotten for our allies (an entire weapons cache, one or two shuttles, a submarine, one or two concussion missile launchers, an E-Web, and probably other stuff I've missed), I wouldn't say our personal supplies are that overboard. The pirates had, as I recall, an undergound warehouse chock full of stuff. My stuff could fit in my quarters.
