For Episode I, we already knew where the story "would eventually" go. For Episode VII, we had no idea, and for all of us, the future of the Star Wars Episode films will be a surprise. So Episode VII.
1) Return of the Jedi
2) The Force Awakens
3) The Empire Strikes Back
4) Revenge of the Sith
-- A New Hope
6) The Phantom Menace
7) Attack of the Clones
In regard to the genetics of Rey. I noticed in her "home" on Jakku, she had a doll of sorts that looked like Luke's outfit from ANH... Is it possible that he gave this to her when he dropped her off to protect her from Snoke and Kylo Ren. With Snoke training Kylo and Luke training her daughter, is it possible we might see a Skywalkers vs. Snoke and Kylo in Episode 8 or 9?
