Oh boy, I haven't felt this hyped for anything Mario-related in years! I can't even begin to express how excited the trailer made me, it looks so huge and never-ending, like you could just keep on running along and exploring forever. That's exactly what I've been wanting out of the series for so long, a return to the more open ended worlds like Mario 64 or Galaxy 1 and 2, and tons of secrets and stuff, like Mario can interact with everything and react to it, that's just so rad! The real world aesthetic is perfect for an exploratory Mario game too, the environment is so gorgeous I'll probably spend most of my time with Odyssey just looking at the scenery, lol. Mario looks cool too, great balance between the Nintendo 64 era design and that semi-realistic thing Smash Bros started, and of course Charles Martinet gives a usual awesome voice acting! If I had to nitpick the sentient hat kinda threw me off at first but it's growing on me, haha, looks like some neat opportunities for platforming and attacking.
But yeah, overall I'm extremely hyped for Super Mario Odyssey, it's got plenty of new ideas but just enough old stuff to keep the old farts like me coming back. Looking rad, I'm definitely buying a Nintendo Switch for it later in the year!
Edit: By the way, the humans don't bother me. I guess it is pretty offputting to see them interacting with cartoony Mario, but oh well, haha. I'd rather have them than anime humans though.
