Don’t remember if it was really ruined in TCW: Yoda just happened to meet a fake Darth Bane ghost.
When Lord Haseo says “ruined,” he means “differed from the Darth Bane novels.”
Ok… well, I don’t really care about SW novels, my only interest for the saga is the movies and tv series. That being said, SW is now Disney, and Pixar belongs to Disney, so an animated adaptation by Pixar of the “Shadows of the Empire” material (novel, video game, soundtrack) is something I would want to see, with Brad Bird involved, and Genndy Tartakovsky as well. The only spin off movie I would be interested to see. Young Han Solo ? Don’t care. Boba Fett adventures ? Sounds boring. Obi-Wan trilogy ? I don’t see the point. How the rebel alliance stole the death star plans ? Filler material, can be fun but I’m pretty sure it will be a pointless movie. To explore the old republic era and the legendary Sith/Jedi schism ? Ok, here you’ve got my attention (Peter Jackson could do something about that, without goofy stuff that have ruined parts of his Tolkien adaptations. Guillermo del Toro would also be the man).
