The general level of erotic games is sub par. That's a fact. Someone with a bit of critical sense can butcher easily 95% of the games of this site in terms of plotholes and characters.
I'm not talking about honest fap material, like 'Project Miriam', 'Her desire', 'Champions of liberty institute, NauthyLyanna and similar ones. I'm talking about ambitious (I would better say pretentious) games that supposedly are trying to tell an interesting story and create relatable characters, like this one, BaDIK, Summer's Gone, A Wife and Mother, Intertwined or The Bite Revenant. Those are the games that come to my mind right now.
Those games have a lot of reviews of 5 stars, but all of them have huge plotholes, Lis that are only attractive because their 3D model are attractive, not because of their personality and traits, stupid antagonist, cliché scenes, unattractive MC to play as, etc. And devs that are creating a role-playing game with a player that controls a MC and takes decisions for him, but that don't know even the basics to create one of those games; they think that are the same rules as if they were creating a comic or a movie. They don't know the difference between 'player' and 'viewer'. That's a fact. So, yes, most of the people doesn't actually ask for quality. I suppose most of them just want good 3D models with big tits and a 'skip' button for skipping most of the text between lewd scene and lewd scene.
