EDIT: Since this thread has recently gotten a fair bit of attention, I want everyone to be aware - I am NOT thinking of Diablo Immortal/anything mobile for that matter. This is supposed to be a computer (maybe console)-based MMORPG like WoW/TESO/SW: TOR/TES Online but simply in the Diablo universe. Darker tones, etc. Or a single-player horror game, but from first/third-person perspective. Please read the post instead of just blindly replying.
Original post:
I know many people talk about World of Starcraft, and I love that idea - but I've been feeling for some time the aesthetic for Diablo would be wonderful for a creepy first or third person game, whether it's single-player i.e. Amnesia The Dark Descent: Skyrim Edition or multiplayer like WoW, but more creepy shit.
I don't play D3 anymore because it's a joke but it was my first ARPG and I always maintain Act 1 was the best act in it. Dark, gritty atmosphere and up close and personal, could be scary as shit. I read the Diablo books years back and one of them painted such a creepy picture in some dungeon or crypt and I thought, man, if only.
What's stopping this from being made? It would sell.
