There is a debate I have noticed on the if of Revan and The Exile returning from the Unknown Regions. If they do, what will they look like? So here is my idea:
I'm sure it's not that difficult to figure out. You would start off with a conversation about the two to determine whether they were male or female and if they were LS or DS. Then, the appearance. Having the game recognize a save game from older games has been done before...can't give you an example but I do think it is quite possible.
Or, if there is the chance we could play as all of them, then the answer would be obvious.
p.s sorry if this has been done beforehand
