A Planescape: Torment redo would be good but I think a sequel would be better. Perhaps as a demon or some planar traveller, seeing tidbits of the final actions of the Nameless One on their own journey. Or perhaps the protagonist is/was motivated because of some action that seemed trivial to the Nameless One, or a certain incarnation of his, yet neither know the Nameless One was the cause. That would also allow for more character customisation.
Other things that concern me:
Filler dungeons- NWN2 was bad for this for example. Every zone had a dungeon, maybe more, and every dungeon you ha
