Working on expanding my predictions/concept to be more concrete. For reference...
- The Mushroom Kingdom/DK Island area is identical to how it would have been in KidZone.
- The Zelda area features Castle Town with a stunt show + thrilling dark ride and the Lost Woods with a maze walk-through.
- The Pokemon area features a Pokemon Snap interactive dark ride, a Pokemon Labs interactive experience, and a flat ride in the center of the area.
- The S.N.W. plaza is a hub between these three areas, featuring a variety of Nintendo series such as a Kirby spinner, an Animal Crossing Roost Cafe, a general Nintendo store, etc.
