No Empire?
What's the most likely scenario if Mace Windu had sabered Palpatine before Anakin arrived, what would have happened?
1. Does Anakin kill Windu in a fit of rage when he does arrive, believing Padme doomed? Take control of the clone army, take Luke as an apprentice, rule the galaxy?
2. Does Windu beat Anakin like an Afghan orphan, killing him in the process and ending the threat of The Sith?
This isn't Anakin vs Windu. it's "What happens to the galaxy?"
