Agreed, here are some risky/out there games I'd love to see on the Switch:
1) A Bowser open world adventure game set in a huge map where he can conquer different lands with his Koopa Legions. Could be set up like Shadow of War/Morder.
2) A "Mario Villians" game (like Lego DC Villains). Maybe Mario and gang have been captured by worse villians (new ones) and the old ones have to stop them.
3) Paper Luigi game set during The Thousand Year Door.
4) A new Paper Mario game like TTYD, with tons of new characters and races, not like the last two with just Toads everywhere.
5) Donkey Kong 64 sequel. The fur needs to be pristine and on point. Does this count as a Mario game? lol
6) Yoshi's Story 2
7) HD remake of original three Paper Mario games, sold as one game with traditional controls changed for Super Paper Mario).
I feel like all of these are things unlikely to happen, but I would love any of them.
