Yes, that was Bioware's intent with this expansion was to reach back to the roots of KOTOR and really have an immersive story. I have certainly enjoyed it all the way through with my Jedi Knight. I believe it has more meaning with my Jedi Knight due to how the Knight's story went and how it's tied to things both in the end of the main game as well as in the Revan expansion. I think I will attempt it next with my Sith Warrior since he too is tied to some of that line.
Update this post when you finish with your Sith Warrior and compare the two please! I don't think I've got what it takes to devote as much time and effort to a Jedi play through. I always quite out of irritation whenever I reach Corruscant. And why is a Jedi killing so many people?? Not ALL of these gangsters I kill with three right clicks could be that hard to mind trick right??
