[Star Wars] During the boarding of the Tantive IV during A New Hope, a random crewman gets a lucky shot and blows Darth Vader's head off. How does the rest of the saga play out?

With Vader killed, there is no one on board who knows that Leia stole the Death Star plans. So Bail Organa's coup attempt goes smoothly.

Leia is released from Imperial custody, lands on Tatooine to find General Obi-Wan Kenobi. She finds him, recruits him, and takes him to Alderaan, along with a boy that he insists must come with him.

The trio arrive on Alderaan and find Bail Organa. Organa receives the Death Star plans and heads to a meeting of the Imperial Senate.

Obi-Wan Kenobi tells Luke Lars and Leia Organa the truth of their parentage. Their father was the dashing hero of the Clone Wars, Anakin Skywalker. Unfortunately, Obi-Wan's pupil turned on the Jedi and helped establish the Jedi.

Obi-Wan takes Luke and Leia Skywalker to Dagobah to train with him, Qui-Gon Jinn, and Grand Master Yoda. They are told of the Sith, and how their father was destined to bring balance through his destruction of the Sith. Obi-Wan believes that balance is his children.

Bail Organa reveals the plans of the Death Star in the Imperial Senate. He is likely executed. Even Imperial sympathising planets become perturbed by what they see. The Rebellion grows stronger than they could have ever imagined. The Death Star is destroyed.

Obi-Wan Kenobi, Yoda and the Skywalker twins defeat the bio-mechanical apprentices of Darth Sidious created by Dr. Cylo.

The four Jedi eventually kill Darth Sidious and the Empire collapses.

With nothing to take control of, or corrupt, Snoke remains a dark side user until he is destroyed by the Jedi Knights founded by the Skywalker twins under the watchful eye of Obi-Wan Kenobi.
