I haven't read to this point aside from the topic post, but I'll just jump in.
I think KOTOR 3 is like the Return of the King. Meaning it should come full circle. I think that would mean all the characters from both KOTOR 1 and 2 party members will also be in KOTOR 3. But to expand on my thought since there are way too many rules, is it ok to talk in reference to storyline on both KOTOR 1 and 2 for my theories on who else will be in KOTOR3? Thanks.
