I'll drop a few more recs. I did a search for the games I have in mind. They were recommended, but there was no feedback from our trusty VN, jufot.
First one is a no brainer. I am confident that you will like this AND it fills all the criteria in the OP. Elvensang. This game probably has the best prose and technical writing ability I have seen from an AVN. The world building is rich. The characters are well developed. The story takes itself seriously. The moral dilemmas are not black and white. The factions are not black and white. Everybody is justified in their own actions and you can sympathize with all parties. If this one doesn't get in the OP, I will riot.
Now the more controversial one. Pale Carnations. This was recommended a while back. It was #1 on the weighted rankings for a bit, and for good reason. I saw your short response to another person recommending this, but I'm not sure if you've played it. It certainly has male dom, coercion, and a bunch of "unsavory" tags, but it doesn't revel in it. The entire premise for the story is a fucked up situation for those girls, but the game doesn't ever fully indulge in those fetishes without remorse. Even the most corrupted version of the MC is very much mindful of his propensity for darkness and does not flaunt it like some male dom crazed rapist having the time of his life. Although I haven't done the route, the good guy MC would certainly be someone who finds himself wrapped up in some bad business, and he is trying to come out of it with his soul in tact and help as many girls as he can. Plus, the writing is excellent on a technical level. That said, if the subject matter is not to your liking, I can see why it might not make your list (although technically, it doesn't violate any of the criteria in the OP hehe).
