Astral Chain (Nintendo Switch)

New item! 
Technically, technically, this game is a first party Nintendo title, so it must take place in the same universe as Mario. 
It doesn't play like Mario at all though, which is a bit disappointing. Instead, it's much more in the vein of Bayonetta or Nier, meaning it's a crazy Japanese action rump. But then again, so is Mario - so why couldn't they just throw in a Toad or something? 

It would've been ten times better and more popular, I guarantee you.
