First of all, as a birthday present, someone who barely knows what video games are got me K2 before I had K1, not knowing they have linked stories, and I still don't have the original so this is all ideas from K2. Now, I don't know what the story of K3 could be, but I have a few suggestions:
1. This has probably been said several times before, but I HAVE to be able to create a character. And I mean actually create. I want to be a rainbow-colored Twi'lek that has 3 arms, 4 legs, and 700+ lekku! Well, not really, but still.
2. I thought the whole influence thing was a great idea in K2, but they didn't really do anything with it. It only unlocked new content, it didn't really effect the story. Case in point: If you're playing as a female, it seemed like not matter how many times you insulted him and how far you fell to the dark side, Atton still loved you. It would be great if you could actually change his mind.
3. A much more active story. In K2, it sometimes felt like you were just walking around aimlessly. The biggest twists were the characters' back stories. I'd love to see a game where you can give the story a break and go around gaining XP and breaking into lockers for an hour, and then get back to your quests and instantly have someone get killed or your ship blown up or something. I know the Sith Triumvirate only had three Sith Lords, but that's no reason for their laziness. The Sith are supposed to crave power! The only power they'll get from sitting on their holocouch or whatever all day is Intermediate Body Slam (No saving throws can stop it, but player cannot attack for 2-4 seconds afterwards)!
