I think that's just an argument for why romance should not neccessarily be a central selling point of a video-game. People get their hopes up too much and then they are disappointed, even though the game was never supposed to be a dating sim in the first place. Again, I'm not against romances, but at this point they became so central to how we judge a game that it's positively unhealthy.
Companies should sell an adevnture first and foremost and then sprinkle romance on top.
I think it's not up to you to decide what's unhealthy and what's not. This is just a function, and yes, someone play game just for sake of this function, just as some play only for sake of beautiful graphics etc.
For me, the possibility of romance in game is one of the most important, and I do not consider it something "unhealthy". I just love this function. Of course, I don't play game just for it, otherwise I would never have played Tyranny, lol. But this is on top of "importance" for me, it's like in top3. I'm much more attached to games if there are romance. And I think it's not just about me, there are many such people. BG3 was never marketed as a "dating simulator", but romance are most talked about topic among people... The expected interest.
I don't understand why people like you should deprive me of fun just because you think it's least important or "unhealthy" for judge a game.
