All of RD's character are copies of each other with some minor changes from what I've seen, or in the case of my DH game, and exact copy of a character he was running in another DH game.
My bad feeling stems mostly from the use of Mari as a character portrait. The character of Mari is what I think of as a excellent example of a Mary Sue. A goody-goody character who has all sorts of talents and always tries to steal the spotlight and nothing really bad ever happens to. Just seeing that coupled with RD made me cringe.
