Personally, I would like to see just a few of the characters back from the previous 2 games. Namely Juhani, Bastilla, and Mira. Maybe throw in the death of Jolee Bindo
oh yeah, forgot to say something about that
. I think that Bastila should return, it would depend on wether Revan killed her or not. I would love to see HK-47, and maybe a force ghost of Jolee.
