When it comes to Character Rules, there are very few, simple rules.
1) No using real Star Wars characters. You ARE premitted to steal parts of names, for example, you can borrow a last name, or a first name, but no Luke Skywalkers, or Wedge Antillies.
2) Use known Star Wars races, try not to start making up new races.
3)You can ask to become a Force user, but the decision is up the the Sim leaders.
4) Be creative and have fun with it!
