I'll be honest, for some reason I can't stop thinking of UCM whenever those types of tweets get brought up here. I mean it fits the qualities mentioned: his idea for a maze, qualities he originally came up with how he wanted it to be structured, tweaks could be made a lot easier to this property without it showing given that we don't even know for sure how many classic monsters are gonnna be in it or in what format. Is it the movie theater idea or something vaguely similar to House of Horrors where it just blends the transitions between worlds. or maybe IP's fit within an original concept structure, where he gives an unofficial world, similar to Titans of Terror in 2017, based on IPs, but fit within an original story. Perhaps the monsters interact with each other and are found in similar environments. IDK those are my thoughts and they're all viable until he specifies with that announcement, which will probably be in several months.
