Yeah, it follows some of the general plot. But Leia is with a rag tag team of Rebels in an Imperial Shuttle until the middle of the story. Obi-Wan and Yoda appear as Force Ghosts to scare the Emperor while Luke confronts them. The Ewoks live in a cave and stuff too. You can tell it wasn't a serious stab at getting it right. I think it was about getting something down to start working out the issues. I like reading those drafts to see if anything ever makes its way into The Clone Wars.
