I sympathize with your desire for options, but with all the storyboards and programming that goes into a virtual game, it is hard to plot around sandbox features. At best it would be picturesque, that is, a non-linear narrative. That undermine any epic tone to the story, and Star Wars tends to be characterized as an epic. In all probability, it wouldn't have much of a story at all -- just a setting and your own imagination to fill in the gaps.He set his in the world of Vader and all that, but as the game progressed (before we became friends) Vader was killed with the emperor.
It was fun because I could literally be any character I wanted, be any Star Wars related Alien and go any where.
He also made his own aliens and hidden cultures outside of the game books.
