In Mario 64 there is a staircase you can run up forever, granted it looks the same no matter how long you have Mario run up the stairs, but that certainly fits "big but uninteresting 3d world."
I know 'interesting' is subjective, but your comment is demonstrably false. Just type "mario 64 staircase" into youtube, and look at the hundreds (thousands? millions?) of videos and many millions of views.
Redefining “interesting” just so you can provide a completely irrelevant “correction” is bad faith trolling.
There's no secret formula to culture. Some programmers and AI people seem to think there is some magic AI model that will be able to produce cultural hits at the click of a button. If you're a boring person, you're not likely to "get" why something is interesting, or why that part can't just be automated away. No technology can help with that.
