This is something I haven't seen anyone talking aboot when talking up the ST. It's all Dark Jedi this and more Sith that (not that I mind, it's kind of a part) but Team Skywalker taking out Jabba would seem to be a big deal. The underworld is a sub-plot of basically all of Ep.4-5 till it becomes the big deal main plot at the start of Ep.6, but it's definitely involved in the series. And I can't, for the life of me, remember much of any EU that had to deal with it, aside from "Hey, thanks!" from Karde or maybe Jabba's uncle in the "Glove of Darth Vader" series seeking vengeance. So, anybody? Also Fett probably back. Hell, even if you listen to the commentary track for ROTJ Lucas even says he considered special-edition-ing Fett popping out of the Sarlac but said he didn't do it cuz it had nothing to do with the narrative of that story. And rightfully so!
