What I'd like to see is a kind of a trust system where the jedi and the sith, if you wish, would grant you knowledge of new ways to use the force according to your behavior. Like when you're being nice to everyone and embracing the light side, the jedi would begin to trust you with more power and grant you with knowledge of them. Eventually they would even make you a jedi knight and then a master.
Or
If you were with the sith, they would do the same when you show them you're strong enough by killing other students maybe or just generally trying to gain as much power and money and such to yourself as possible, by any means.
Or
You could just go roam around without any alignment and find out about the force yourself.
