I'm glad I got a little conversation going about the MC.
Ok so " He hasn't neither the training nor the experience to play hero." So he's a 'greenie' and shown to be an impulsive guy there is still no reason that his character cannot grow through the game's situations. I mean, who of us wants to be a thoughtless, ignorant 'pretty boy' that stumbles through life? ...and how realistic is that? If he wins all the confrontations in the game through luck, accident or deus ex machina, how much fun it that?
How much better to see him grow up, start thinking before he acts and acquires some character traits by learning something to fight for, something important besides just rescuing his sister. That would really enhance the 'ride' and make the game much more satisfying.
It is already a good game, make it a great game. Let the kid from Tatooine find some strength in the 'force' and set out to save the sector and civilization. It may be corny but it sure is fun.
Ok, again this is all IMHO and offered in the hopes it helps the Devs build a great game out of one that has that possibility.
