Loved the final act!!
No, really, I thought it was the best part of the whole storyline. I finally felt my knight had a purpose instead of merely investigating some ominous dark thing in the corners of an unending maze planet.
Sorry, original poster, I have no sympathy for you. Personally, I wanted to bring Scourge. I loved the idea of him to fight his one-time master (how deliciously Sith!!) and was surprised I had to bring my undergeared trash can. But, it did make sense story-wise so I pitied my poor droid for the many deaths he was about to face and made the best of it.
In general, this game punishes ritalin junkies for rushing through content and racing to the finish line. I like that. Read the dialogue, follow the story-line, enjoy the game. Did you have it all figured out? Did you expect one solution to solve all problems? Hmmm... If the developers found a way to surprise you while also staying within their story-line context, then good for them and good for you. Enjoy.
Well done, Bioware, well done. I hope the next character's storyline lives up to this one.
