Imagine a Nintendo Land. An F-Zero attraction where you sit in actual cars, get an oculus rift type helmet, and play etc.
DK Country type walkways and tree houses, Hyrule Castle with a triforce that glows when you touch it etc. Luigis Mansion haunted house tour, Pokemon snap type safari using state of the art animatronics.
