I liked the story the best. It was indepth, told the story of the Mandalorian Wars and Exile's involvement with Revan, what happened to some of your characters from the first game and what was going on during the Jedi Civil War.
An open ending? I found it stupid and incomplete. I go through Kreia's banter on what happens to my companions, toss her sorry ass down the abyss and the next thing I know they show the Ebon Hawk flying away. Like WTF?
