My ideal would be that we don't ever get a "BG4," by which I mean a game with "Baldur's Gate" in the title. I'd want a completely new series and franchise, and if using the FR then in a part of FR we have NEVER seen in another game.
Has any game ever gone to Waterdeep? I constatly hear Waterdeep this and Waterdeep that, but never seen the place.
