Played through the main story mode of Super Mario Odyssey yesterday- I muscled through that in pretty much a day, but there's a lot more to explore in it. Yeah the plot is the same lame old Damsel in Distress (made a bit worse by the "and Bowser is plundering all these themed lands for wedding gifts", and a big wedding scene at the end, though tempered by Peach saying forget both of you, I'm not your damn trophy and am going off on my own adventure) but its capture mechanic ("Remember kids! Keep on a hat lest you get possessed by Mario!") really delivered in one of the main things I play video games for: engaging physics and alternate controls. Taking over a Tropical Wiggler to stretch around a bend (with subtle squeezebox sound effects) or using a Poki's beak to sproing up a wall are visceral delights.
I'm impressed too by the Switch, I was thinking that the ability to play away from the TV like a tablet or Gameboy wouldn't be that useful since I don't have a commute, but it really adds some nice options , playing in bed, or in the living room when something else is on television, etc.
