Especially now with ever increasing rates of ADHD and other stuff, having an old school genre like an RPG have that type of stuff as a "reward" for beating a level or whatever reinvigorates a genre that felt outdated due to a lack of a proper reward structure.
Fact of the matter is, if you as a game dev want to make money, better lose your inhibitions real fast, because the consumers, want more choices in their game, even if it's just romance for the most part.
Look at stardew valley, I would never have played it if I hadn't found out you could literally date and marry a girl in the game, it just added a layer of reward to the gameplay.
