Media in real Mario games

[RaymanFan1995]

I thought super Mario Odessy already did that kind of thing.

What I mean is, instead of a 3D collect-a-thon platformer that takes place in an alternate "real world", it would be a 2D "point A to point B" platformer with pixel graphics that takes place in the Mushroom Kingdom, but with actual new world themes, mechanics, and gimmicks mixed with traditional ones, similar to Sonic Mania.
