this game will presumably be on all 3 next gen platforms (360, PS3, PC) so it will, undoubtetly, bring in lots of newbies to the franchise.
partly for this reason, I think having Revan and/or the Exile as controllable characters is a bad idea.
I want them to be major, scripted characters (and not shipmates, either) like Kavar and Vrook.
Because of various situational issues, they are not able to fight the antagonist head-on and that is where the PC comes in.
