I feel like accents would bring little new to gameplay and they would require lots of money, time and effort to implement, because they would basically need all the voice actors to act out the voices again but with the different accents. I would rather they spend the money on implementing other cultural things, like different greetings or habits, customs, dances, foods, etc. I am still hoping they will one day bring back the hula dance which is sorely missing from Sulani.
