I've only read about half the ideas so far but i have to throw some of mine down.
Somthing I would like to see is have more challenging boss fights where strategy is needed to some degree. Like some team work between your party members.
Also some possibility to take your character you finished the game with and having extra stuff to do, or have the ability to start the game over with finished character so they can use all the cool stuff you got from the start maybe having the story change since you are strong the second go. like new game+ option.
I found there was little to do after getting all the final upgrades for light saber and armors in both games.
also LS DS options could be a little less extreme maybe they could trick us up with options you might think good intention but effects somthing else...
I like the hood idea people are wanting.
More character custimization would be nice.
