I know you meant in terms of being story heavy rather than tone or narrative. I was just pointing out how two story heavy games can be amazing despite differing in so many ways. It is not usual that an h game will make the player think let alone think if very different ways.
Not only that but the contrast between the two could lend itself to some very funny memes. Just imagine Bad Luck Brian as Luka and the Overly Attatched Girlfriend as the white succubus.
I think in this case they would be succubots XD
Just to complement on why I have a different take than MGQ. I didn't play much of it because it's not my type of story.
But from what I could observe, he treats every monster girl as people, or in other words, another race. So coexistence is possible.
My take on SC was to make sexy parasite girls that are demons, like the ones in Diablo.
They would never form villages and try to live as common people, like the succubi village of MGQ.
They also go "full hentai", making every enemy you can face a monster girl. I'm not saying it's bad, but it's not something that I particularly agree.
For a darker, more serious story, I prefer a limited number of "monster girls", like some type of monster/demon/parasite that specializes in seduction of her victims. Considering that demons usually prey on human weaknesses, you can be sure that there would be some specialized in that.
But for me, only a few types should exist. Imagine playing Diablo where you have monsters of all kinds, none of them sexy girl, all of them monstrous. Then you finally face a succubus, and she'll tempt you, ride you, suck your life and leave only a husk behind.
Imo, it adds to her and her kind. Of all evil parasites, she's the one who represents most danger for human men, making them unique and more desirable.
