I don't disagree with any of your thoughts on genre whatsoever; horror is undoubtedly fluid, which is why it's so powerful. But it's kinda beside the point that I'm trying to make, which is that a GoT house would have felt like an attempt to shoehorn a vaguely horror-related IP into a very specifically horror event simply for the sake of its huge popularity. That's not a good look, IMO. It's blatantly commercial, and I would have had a hard time seeing it as anything other than a marketing stunt. And I know it's not like they haven't done this kind of stuff in the past—I mean, what is a Purge house or an AHS house or even a Creepshow house if not glorified marketing? But GoT just seems too far afield.
