I'm going to gently disagree, while keeping in mind I have limited experience with romantic relationships of any kind.
I like how dos2 and bg3 are open for queer relationships but its just except the pronouns dialouges are all the same, gay relationship works different than straight relationships.
This is surprising to me. From what I can tell, the main difference between straight and gay couples is that the latter need to deal with societal perceptions while the former don't. Other than that, all the dynamics are the same. I'd posit that in a world where no sexual preference bore any stigma, conversations between gay and straight partners would be exactly the same, save for the pronouns.
It's just whats the point of being queer if they are gonna react same to me wheather I am man or woman.
This is confusing to me. Does sexual orientation have a point? Does it need a point?
as others mentioned, characters all remaining potentially romanacable by the PC, but having dialogue within their relationship texts to touch on it and give it a feeling of realism...
I don't see how realism can be balanced between every charcter acknowledging that sexual peference is a thing and yet still being open to relations with Tav. If sexual preference is worth talking about with the NPCs, that means it has an in-world impact. The fact that no-one mentions it means it's not a big deal to anyone. Isn't that a world you'd want to live in?
I feel I've reached the limits of my expertise. My gut instinct is that Earth would be a better place if relationships worked more like they do in BG3 and DoS2. We already have enough clerics telling us how they feel about specific orientations.
