It would be the Skywalker saga if we were allowed to see what happened to Luke and Leia (and her children) after ROTJ but Lucas in insisting that is the final episode has made it into the Anakin Saga (or as Lucas put it with Vader dead "There's no more story to tell").
When watching ANH back in the day it felt like there was a much bigger story extending way back into the past, way back into the future and with more going on in the present than we were seeing on screen (just like the real world).
I've allowed myself to wander way off topic so sorry about that.
Perhaps someone should start a sequel trilogy project thread.
