So what are you saying? That in ANH the rebels destroy a half built death star and in Jedi the are up against a complete one? Wasn't the whole point of the attack in Jedi that the Emperor tricked them into thinking it was incomplete when in reality it was fully operational?

Or are you saying there is only one death star throughout the 3 movies and we see it develop over the course of the 3 films until it is finally destroyed in the finale of Jedi? If that's the case, what happens at the end of ANH? Han and Luke rescue the princess then go straight to Hoth?
