It would be cool that somewhere in the game you would be given a choice of unique (and upgradable) robes (hodded or not), masks and lightsaber hilts to dress your DS user with.
Lightsabers should also have a x% of breaking the opponent weapons (like 30% for swords, 15% for blasters, and less then 5% for lightsabers.)
2 or maybe 3 totally differents storylines (LS, DS , Gray) not just one that have some changes depending on your actions.(maybe too much asking here but we can all hope)
