A Sith army led by Darth Revan. Yep, that's the one thing I'd want. Then I'd get Dr. Doom's time machine, and we'd go back and... take care of George Lucas before he could make the prequels.
And returning an old thread to the light of day just to say "this shouldn't be here" - maybe my Sith army will have another target. Bahahahahaha!
