Im pretty sure most games have verticality, thats not exactly anything new here.
Not semi-isometric RPGs ala Baldur's gate, NWN or Dragon age.
I also would like to remind everyone that in said older games, things that are possible in BG3 weren't possible at all, like going under an archway or a bridge...
You could do all of this in Dungeons and Dragons Online and in other RPGs since Morrowind. The former had a notoriously difficult up down exploration quest called 'The Pit', and ladders, ledges and immense verticality beyond anything in BG3 so far.
The issue was that people that wanted remakes of BG specifically demanded not to have any verticality as they wanted them to remain fully 2D like the originals.
