I had a discussion with someone about playing an established character in an RPG. the genre was superheroes, so we were discussing playing an established superhero, as opposed to making an original character.
Their opinion was that there was no way they wanted to play an established character.
I love it. My argument was that actors want to play Hamlet or Juliet. If you are given full autonomy in playing an established character, but can make them your own, why would you not want to do this, to put your stamp on them?
