So after making this thread while at work, I realized I hadn't done any of the challenges. And yep, that's where the rest of the unlocks are.
And I can say that after 4 hours of screaming at my xbox, I only have 2 sabers left to unlock and one costume. The costume is for choosing to go "Lightside" (whatever that means for Mr. Starkiller) at the end of the game. Which, by the way, I refuse to do. And aside from wanting to keep my thumbs from bleeding, I don't think I will be attempting any more challenges before this bad boy is due back to Blockbuster.
10 bucks for a 4 hour game seems not even worth it, let alone 60
Happy gaming fellas,
