So there would be no Yodah.
You wouldn't know that Luke and Leaia are siblings.
You wouldn't know that Darth Vader is Luke's dad - Lucas originally had them two different people

“The franchise something in common with Star Wars. They never imagined it would go farther than the first movie, so they had to imagine some grander story to fit in retrospect.

Don't get me wrong, I LOVE Return of the Jedi. But really though, compare all sequels to the orignial(apes)...

From Wiki: One of the controversies surrounding the 2004 DVD release of the film was that the "ghost" of Anakin was replaced by Hayden Christensen, though Shaw is still the one shown as Anakin/Vader in the scene when Vader is unmasked, and is the only actor credited with the role in that film. In 2006, another DVD release featured the original version of Return of the Jedi, with Shaw restored as the ghost of Anakin Skywalker.

I didn't realize they "put him back", so to speak.

Looks like the baby version of that thing at the start of Return of the Jedi.
