ok this has been done before, but that was quite some time ago now...I think
The concept is that you "make" an RPG character, you can describe him/her/it in anyway you want, as to what class (ninja, samurai, fighter etc.), and weapons looks, anyway you want the character to be, and last the most interesting part..usually atleast the biography.
How the character got into adventuring etc.
If he is seeking revenge, or if he is just travelling.
