It'd be cool starting out as a Master. How much farther could you go though before you became a freaking Jedi God? In order for the game to be any fun, the dev's would have to crank up the difficulty to an enormous level. I can see it now, I'm running around on tatooine...
T3: Beep-boop-beeoop!
Me: Holy Tallness T3, That Jawa is the size of a ronto...
Yeah, I don't know how they'd pull it off. It'd be cool though. Of course maybe you could start out as a Master, then run into some other ticked off jedi/sith who could cut you off from the force...again. Actually, that'd be perfect, because then you could be found floating through space, aboard a beat up vessel called the Millenium Falcon (hey, it had to start somewhere) and be nursed back to health by Carth (for the ladies) or Bastila Anyways, it's a thought, but yeah, other than that one problem, starting out as a master would be pretty nice!
