When watching A New Hope, and the droids are trekking Tatooine, there’s meant to be an air of mystery. You don’t know what you’re gonna find.
The Prequels ruin that.
So I propose turning Tatooine into Geonosis. This would be done through color grading and new mattes. Then have it so Yoda and Obi-Wan move the Lars and Luke to a different planet to increase the chances of Vader not finding them.
