deathatthedoor is right. no way we can tell as it's still a long ways off before knowing what's actually implemented in the game.
still, DAD's idea of having a fleshed out character is very valid, only that it may not work in RRR, if the character is really dragged into a demonic dimension where he/she is a total stranger except for his/her demonic half. even then he/she may cope better as the character is now some sort of a soul-forged freak & such combo is/can be acceptable in the demonic dimension. had it been rivellon, everybody will attack the freaky character without asking for name & ID. whatever it is, the outcast character will not be well received anywhere & so reputation is close to hostile level or worse.
DAD's idea of having a point of reference is great as well. if u're a convict & u managed to escape from prison, where do u go first? back home 2 see your family? or look for your best friend for help? or what? now that's role-playing.
