Everything feels so FRESH.
I'm getting "Alice in Wonderland" vibes from a number of things, most notably the hat motif and white rabbit bosses. Not only do they remind me of, well, White Rabbit, but they're dressed like the Mad Hatter.
All of the surreal places feel like a trip down the rabbit hole, too. New Donk City looks like a photorealistic NYC circa 1980. The Mexico-themed world has a day-night cycle, living sphinxes and Day of the Dead imagery. The jungle world is dark and industrialized, with sprinkler robots and rusty rigs. And then you have the abstract food world with its highly stylized low-poly graphics and bright pastel colors home to living forks, a featherless turkey, and Hammer Bros that wear chef hats and throw frying pans.
To quote "The Nightmare Before Christmas:" What... is... THIS? Whatever it is, it's magical. Imagine if someone had leaked this (like an actual description of the levels, not just the name). It's something I can still hardly believe, even with this amazing trailer at my fingertips.
So exciting. And to think that 3D Mario usually look weakest at the start and appear dramatically better by the time the game releases. If the game looks this good NOW, and it's not out until Holiday 2017... Imagine how epic the final product will be. :-O
