I'm game to speculate a little on a 30-year Anniversary house:
- I could see a Psycho scene in there, since that was the biggest early IP house and made appearances at BOTH HHN 3 & 4 as well as 16.
- I think TWD could have a scene since it showed up 5 consecutive years and was a big part of HHN lore even tho some of the houses were disappointing.
- The People Under the Stairs makes sense since it was the first IP at HHN 2 AND made a reappearance at HHN 16.
- Scarecrow makes the most sense of the recent years b/c it was so damned good & there has been scuttle it could return in some fashion.
- Body Collectors has appeared 3 separate times (I think) and had some really good moments, so I could see that represented as well.
- Halloween makes a lot of sense because it's a staple & Michael Myers is an iconic "monster". Also a lot of great scenes to choose from.
Others that I could appearing would be: AHS, Evil Dead, TCM, Legendary Truth, and Slaughter Sinema,
