Out of all these options for a new chapter which ones would you want?

I don't want anymore IPs

A quality of life chapter

None.

Don't get me wrong, I don't know many of these options, but I'm not a big fan of including the "wrong" Pop Culture franchises. Mainly, characters that don't really are "horror". D&D is not horror, Resident Evil is arguably not horror as you are the hero gunning down enemies and its style doesn't fit the game. Silent Hill IS horror, by contrast.

Tokyo Ghoul, being an anime, had me wondering, but they made Kaneki's looks fit the game. Still hate playing against him.

I didn't mean the later games in particular. Even in the earlier games, the player was a "doer", proactively fighting against the monsters. He was expected to succeed. Resident Evil was never about horror to me, not more than Castlevania, which in my eyes was the worst possible Dracula version they could have included. Castlevania uses characters and imagery from a classic horror theme (Dracula) and sieves it through the "everything is rad and cool"-filter of video games, losing the horror vibe.

Horror is about helplessness, facing the unknown without a safe plan to fall back upon. Being the hero wielding a weapon that solves the problem disqualifies any franchise from being horror.

You could argue that you also have a weapon in Silent Hill, but the horror there does not come from the threat of the monsters but from the "human monster", the dark secrets of the protagonist (in Silent Hill 2, at least, where Pyramid Head is from). It isn't the hero's objective to bring an enemy down, it is facing his own darkness and ultimately there is no happy end; the best you can achieve is surviving and coming to terms with the dark past.

I do enjoy Silent Hill games also and considering what you aim for. I can only say that sometimes the higher difficulty is the way to go, they even tell you in some newer Resident Evil games that choosing hard - less ammo, weapons on start etc is the difficulty you should choose as a series veteran. My best & closest experience to what you seek was in Resident Evil 3 original game. I was a teen there and fear had much more impact on me, but also the game had a monster called Nemesis in it and he often randomly show up in the city locations, make sounds and seek you to kill. Nemesis didn't care if you had a lot of ammo for your hand gun, shot gun or m-16. He could soak it easily and throw you like a rag doll all over the place and some of his attacks could instant kill you. I was always scared when he show up and I run from him most of the time, just to see him chase me to other city locations, it was tense and scary that a killing machine like that can pursue you for so long and you are hopeless despite the guns that in normal world should make you confident. Especially if you play at the hard difficulty - you had a hand gun and few bullets at start here and also it was the intended one, because only on it Nemesis drop special weapon parts. They even made a Nemesis "desktop pet" app back then and I once had it launch and run on my screen and making noises while I wasn't aware of it and then I was playing the game…for a while I was a paranoid in my game experience because I was waiting all the time that he will charge on me, before I realize the Nemesis "pet" is making all the sounds on my desktop😁 I feel like it was the most intense RE game for me and it was a very disappointing experience to see how they made the remake.

In the end I just wanted to share some of my experience here and show why I feel like I feel because of it. It is enjoyable for me to exchange that and see what other people seek in this game and what horror fans desire in it in this community.😜
