Maybe this isn't something innovative but has consideration ever been made to role-playing or adapting to role-play famous people in history such as Napoleon, Caesar, and others? If that did happen what kind of character attributes will they have?
There are actually modules designed around certain parts of history and the famous people in them. I've never thought about actually playing the famous person as I tend to play my own liking.
In a certain magazine there used to be a section like this that put real persons in history as well as known characters into Role-playing Game form so they could be playable.
