Well, each to their own. Imo, porn games (well, masturbation in general) are meant more for releasing the steam through sexual events/narrative than genuinely capturing the core attention of other games mechanics. If I desired a grindy game then I would play genuine RPG/MMOs that are meant for that purpose. I only play porn games, because progressing sexual narrative makes it worth it, if I don't need the urge to fap then porn games are pretty much useless as dedicated "games". The same way mobile "games" are dozen of times inferior to dedicated cnsole and PC games.
