Well, right now I have two separate ideas. I have one that is basically a bunch of colonists exploring a new system at the end of the Great Sith War. I have a pretty good idea of where I want it to go. The colonists will land on a planet and attempt to colonize it, meeting challenges such as gathering food, water, and forming a relationship with the natives.
The other idea is the cleansing of Tatooine. A group of Jedi will land on Tatooine and have to flush out the remaining Sith forces with the help of a few colonists/natives.
