This is very true. The Maze Design team are very good at what they do. It's like walking on a movie set ( in my opinion) but the maze theme doesn't necessarily have to relate to its surrounding architecture. Look at The Ripper Maze. Inside, it was set up as Old London and outside it was Hillbillies. It was a really great concept - you get chased by Jack the Ripper on the inside and when you get outside and you think you're okay, the hillbillies scare the absolute daylights out you. And Texas Chainsaw/ Southern surroundings kinda go together. It's possible that the house in the maze is the mansion that the grandmother left to the main protagonist in TC 3D
