Kreia is one character I took with me on all planets except where I wasn't allowed to. She was just so mysterious and insightful. An amazing character to be sure.
I'm not sure how it will play out, but I made every effort to keep my influence up with her as a Sith Lord (even to the point of reloading scenarios that caused a drop) because she is the lynchpin to the story and as far as I could tell, you wouldn't get the whole story unless you got it from her.
When I eventually finish my Jedi (or create a new one) it'll be interesting to see how much of the story is 'missed' because of conflicting ideologies.
I swear I just want to take my newly crafted, green-colored lightsaber and slice that hooded head off her!
Yeah that thought went through my mind on numerous occasions.
What a game indeed!
