The toughest is Bao-Dur and it's not really worth it for him anyway. You have to have him with you to click on very specific conversations and items and if you miss even one, you'll fall short.
It's fun to have Atton, Mira, Disciple/Handmaiden as Jedi though, particularly for the Dxun / Onderon mission.
KOTOR 2 is an almost masterpiece that still turned out to be a pretty good game.
The plot is much more complex and intricate than the original and more ambitious, but I agree with your assessment that it falls short perhaps because it reached a little too far and wasn't completed properly.
KOTOR 2 also had the advantage of building on an existing engine and graphic sets etc., which in my mind makes the original that much more compelling.
What's cool about the original KOTOR is that everyone has a different favourite planet. I liked Manaan, but other people preferred Kashyyk, Tatooine or even Korriban (or Taris in your case).
Also, Bastila was probably my first video game crush. That Jennifer Hale is something else.
Finally, the soundtracks by Jeremy Soule may be the best I've encountered outside of maybe the Heroes of Might and Magic series.
I kinda don’t like how you almost have to look up what to do beforehand to get things like that perfectly right. Really wish I at least tried talking to him, The handmaiden, and Mira more though.
Now that I’m thinking back a bit, that part with Goto’s droid and Bao-Dur’s droid never led to anything did it? I wonder what their plans were for the second part of this game.
I’d actually say mine was probably a tie between Taris and Korriban. I enjoyed myself way too much killing all the Sith. My character was as evil as they come. Manaan might’ve been my least favorite haha, but yeah everyone’s different there.
