The Star Wars universe is one of the most comprehensive and massive fictional backdrops every created in history. There are over 20 full length novels alone that take place after The Return of the Jedi and even they, rich as they are, account for only a part of the massive amounts of information. The original KotR had a great story that actually managed to enrich the Star War's universe. Thankfully, Obsidian has outdone themselves with the imagination and depth of The Sith Lords. I would go so far as to say that KotR II's story surpasses both the original's and Episodes I-II. While people may disagree with the comparisons, I think it's safe to say that KotR II's plot is excellent, even though it does have its flaws.
