This post contains significant spoilers for the Sith Warrior storyline in Star Wars: The Old Republic.
I finished the Sith Warrior storyline today. I did it without the class XP buff, so the old way with side missions. I played a female Juggernaut (tank) and went pure Light Side (except for two choices).
Overall, the story was excellent. The female voice actor, Natasha Little, was outstanding with a very rich, strong voice that perfectly matched the character. I also thought the story was very even, more than the other stories I've played. Each chapter was solid. It also was a superb story for the Warrior, demonstrating the rise through the ranks of the Sith.
The main villain was also good, and killing him at the very end (one of my two Dark Side choices) was very satisfying.
I also like the way Light Side worked in this story. Not so much a good person exactly, but more like a pure knight of the Empire, not spending time and effort on unnecessary and petty cruelties. I was wondering how the Emperor would react to a Light Side warrior, as you become his Wrath. But it was portrayed perfectly, as the Emperor simply did not care, was beyond the petty LS/DS conflicts of this galaxy.
The companions were mostly good. I especially liked the rivalry and contrast between Quinn, the smooth calculating officer, and Pierce, the rough frontline soldier. I used Jaesa most of the time, though.
So far, I would rank the story second, behind the Imperial Agent. It's close behind in quality, but the Sith Warrior story is just missing that final "something" which would have pushed it over the line into brilliance.
Sex and the Sith
Because Star Wars is a PG world, sexual depravity is not present, or is glossed over. The closest it comes is having omni-present "dancers" in the cantinas and as slaves.
You know that in an adult Star Wars, the Sith would be utterly depraved. Power structures specifically elevating the powerful over the weak. A code decrying peace and elevating passion. An entire aristocracy focusing on cruelty and power. It would be the worst of human aristocracies, without even the slight mitigations of chivalry and codes of manners.
But for the most part, this is not present in game. Relationships are almost entirely consensual.
Except for the female Sith Warrior romance.
Now, I haven't finished the full story line, but the initial relationship with Quinn is textbook sexual harassment. The superior--both in terms of rank and personal power--continually propositions her subordinate. The subordinate does his best to avoid or deflect her attentions, but he cannot afford--the cost might be his life--to outright reject his superior, and his dialogue reflects that.
It's very different from the Sith Inquisitor romance, where there was clear interest from both parties.
I found it really interesting that Bioware would include a "romance" like this. I cannot decide if it was the correct thing to do or not. On the one hand, a Dark Side relationship with undertones of imposed power seems appropriate to the class. On the other hand, it's much more deviant than I expected from the game.
The romance probably becomes more mutual as the companion story line progresses, though. We'll have to see.
