Baldurs Gate 3 has an advantage over Pathfinder - Drow. There were no playable drow in the Pathfinder, just a couple of minor NPCs.
Pathfinder had a lot of interesting demons and succubus for every taste and color. Larian, do the same with Drow in BG3 and you will win. You can even add Eilistraee's drow for good playthroughs. Maybe even show the whole drow city, their society
Is there a concept from FR/D&D that Pathfinder didn't just appropriate instead of coming up with its own stuff (I know of at least one - the gith)? I am aware that it was supposed to be a D&D setting once (though I may be wrong), set in the common multiverse, until it struck out on its own with Paizo opportunistically offering a 3.5-like in the form of PF during the dark 4e times. Otherwise, apart from small details (like elven and gnomish physiology and mindset, for instance), they just took things and stuck them into their setting almost as-is.
