Which Mario game do you really want to get a sequel?

You can also answer a spinoff here, such as Mario Tennis Aces 2 or something.

For me, it is an extremely easy choice. Super Mario Odyssey 2. It would be so fun to experience Mario Odyssey again, presumably with new stuff!

You guys can actually share your ideas about the sequel if you want, and also, you are allowed to say something like my other "sequel" idea, Mario Kart 9.

Honestly, who doesn't want MK9 at this point? It's MARIO KART. 9.

Pretty much anything under the Wario umbrella, especially the Wario Land series, it's been nearly 13 years since Shake It came out and I really enjoyed it both when I was younger and replaying it through semi-recently. It's a pretty solid platformer that takes advantage of the Wii's motion controls. Why haven't followed it up since is a mystery.
As for the WarioWare series, Gold was a great entry and was much needed after the 8 year gap since DIY, so I don't think it's as needed, but a full new game in the style of everything from Mega Microgames to Smooth Moves would be a great addition to the Switch's lineup.

I would say Super Mario Galaxy or a new Mario and Luigi game.

I miss the Mario and Luigi series, I've had a lot of fun with these games (and the ost was splendid).
