A VN/RPG that has romance and doesn't make it an after thought. Like in most persona games or fire emblem games or even like mass effect. When romance is a thing, once you hit that we're a couple button that's pretty much it.
But then VNs represent the opposite end of the spectrum where you make the decision to pursue someone and that's it, the entire narrative shifts to completely focus on that. I want a middle ground, where there is one structured narrative that asks the question "How might chasing down the big bad change if this person versus this person was the person most important to the main character"
Like for example of you wanted to woo the nerdy tech wizard, following his or her story might involve tracking down parts and materials to improve tech and brace against the coming of the bbeg. On the other hand of you want to romance the overeager hothead it might involve trying to take the fight to the bad guys while saving puppies and children along the way. Completely different paths with the same end goal of defeating the bbeg.
