This is more of a question than a suggestion but here it is.
I've read a majority of the posts and i'm liking the ideas everyone is coming up with but here are my questions.

How would you gain experience? (i've read through classes but is that it?)

And once you gain experience to ''buy'' force powers will others have to be attained first before others can be used. for example, must have force pull and push before getting force saber throw.

Knights and higher give you XP and Force Points.

XP and Force points are just the same.
There is currently no order to "buy" the Force powers, but there is a limitation on the available power levels depending on the XP and Class.
