This is a really nice Nintendo touch. theyc reate environments that become iconic.
Think the Mario 64 Castle's exterior, Ocarina's main field and now Wuhu Island. It really dawned on me when I saw Wuhu Island that it was Christened with that kind of "magic".
I wonder if they pick and choose very carefully which environments they will turn into staples. I can recognize quite a few benchmarks and signals that can be found on all of those, especially now with the inclusion of Wuhu Island. My guess would be they don't want to wear this "magic" out too much, but they certainly have it in their secret knowledge of design.
