I also dont want Baldurs Gate 3 to be morrowind, my personal favorite RPG.
Some games are some things and other games arent those things.
And Planescape Torments writing simply doesnt work in every game.
The only good "Planescape Torment spiritual successor" that actually pulled it off in my opinion is Mask of the Betrayer which was pretty good, but even that wasnt particulary wordy and most of it was just an adventure in a strange land
