I'm about one movie too late, but I really liked the Jakku planet idea in The Force Awakens. A junk planet filled with relics from earlier Star Wars movies. I wished we'd spent more time there, whether it was necessary or not :). I wanted to give my own take on the junkyard planet inspired by modern shipyards where cargo vessels are taken and deconstructed piece by piece. As a lengthy and profitable process for something as large as a star destroyer, why wouldn't small scavenging operations popup and build themselves into little towns?
