What interests me most about all this is how many of these ideas that obviously more sensible people convinced George to drop or heavily alter for the OT cropped up in (or were shoehorned into) the PT, once he had absolute control. Almost as a middle finger to those people who reined him in in the 70s.
As interesting as the drafts are to read, I wonder if we all would have loved Star Wars like we do now if Lucas had been able to run with his original plan. I feel like the answer would be no.
