But apparently criticing that is frowned on a porn thread, so I've learned from certain simpletons here.
Or, and I'm just throwing a wild thought here, people just disagree with your criticism, or at the very least find it overblown because of your harsh choice of words.
I think your criticism of the characters doesn't make much sense for the kind of story ORS is trying to tell, changing Jeremy to be "nicer" or Seymour and Axel to be more "complex and interesting" (which I don't find them to be particularly lacking there either, I feel any significant increase on their complexity would border on subverting their roles as clear villains) would do nothing for the story of ORS. You
could make interesting characters that fit your ideas and build a
different story around them, but at that point you're just making a different type of game from the games Eva Kiss wants to make (her appeal has always been the sheer quantity of choices and ways different scenarios can mesh, which, to be workable at the scale of her games, requires relatively predictable characters).
I don't have much of an opinion on the quality of the dialogue in ORS, but I feel that's more of a technical element and good criticism of it needs to be able to point out specific, or at the very least recurring, flaws in Eva's writing. Not vague stuff like "it could be better".
Just try to not take disagreement as a reason to get combative and call people simps, you can feel strongly about things that other people do not, but it does not make your taste more refined than theirs and neither does it make you some kind of free-thinking literary genius.
