Hi there,
Thank you for bringing this up, I am myself a huge fan of this game. The universe they set up, is, in my opinion, one of the richest and most fascinating scenarios I have seen for a RPG. Surely this is too good to leave it to waste, so it would be wonderful to see some new game set up in the same universe, not necessarily as a sequel but maybe as a prequel of how e.g. Kyros came to power.
Dreaming is for free, so let's hope for it. For me, this game is already a game of Cult in the same level Baldurs Gate II or Planescape:Torment are.
