Wouldn't it be awesome if, in the future, your characters companions could be other characters you've created? Say you have multiple characters. And they could somehow all be integrated into your story. Maybe threw the Legacy system. You could pick there back-stories, personalities, and relation to your character. And perhaps it could go beyond that. What if threw the Legacy system you could create the antagonist of your personal Star Wars saga.
I thought about that at first, but it would not work story wise from chapter 1 to 3 because everyone has major impacts to the overall story. In future chapters that would be awesome. A Avengers type thing would be cool where everyone comes together in one battle.
