+1 Is this a fantasy world sword and sorcery rpg game, or an otome game? Are we heading towards: Quest - kill 5 Selunites to gain 10 points of approval from Shadowheart. Torturing to death - bonus 2 points per kill. Reward - she will hold your hand in public.
I believe there is a reason so many great movies and books have romance in them. And you don't go calling them romance movies or books just because they have those stories.
There is only so much universal things that alsmot all people can relate to and I think love is one of them - be it the metaphysical or physical kind of love. It's not surprising people find it enriching in the stories they experience.
And I'm happy more games have this optional component woven into them and that it's not just an afterthought anymore. I don't think BG3 goes into a direction you just pointed at at all.
