I vote Halo. Precursors were beings of pure energy. In no time they would harness the force and then infect the EU with the flood. Jedi are powerless and are now fighting their infected brethren also wielding their same weaponry. Once all of the stations and ships are corrupted with the grave minds the Precursors retreat to a shield world, fire the rings, and destroy all life in the galaxy. They resurface after and repopulate humanity. I vote Halo.
