I though it sucked. I chose dark side and understood why kreia did everything she did. then I went light and ashe did the same thing.
I was hoping it would divide all your allis and make them fight to the death while you and the other jedi Fought Kreia, Sion, Revan, and Nathilas.
I know it sounds like a corny ending but they could have made it differently from the dark side...
