1) *cough* An official Mod Toolset with Tut.
2) Character creation similar to SWG: Ability to modify everything from eye color and shape to body type.
3) Multiple ship styles available for PURCHASE by the Main Character.
4) Ship Customization with limitations based on size and type.
5) Helmets... not Masks
6) Better unarmed combat: Utilize motion and give moves similar to Martial Arts.
7) Better Lightsabre combat. Acrobatics and gymnastics worked into the combat style.
For now, there's my two cents.
