If you had the choice to make the next Mario game, what would it be?

A Mystery Dungeon game starring the baby characters.
 
I'd have a real hard time choosing one but I'd absolutely love any of the following:
  • Galaxy 3
  • Odyssey 2
  • 3D World 2
  • Mario Maker 3 (with how recent SMM2 is I doubt this will be soon but yeah)
  • Mario Maker with actual 3D levels, especially an SPM or Galaxy theme
  • A new M&L game with good story elements
  • A return to form Paper Mario
  • Remakes of:
    • SM64​
    • PM64​
    • TTYD​
    • SMRPG​
    • SPM​
    • PIT​
    • MP1​
    • MP3​
    • SMS​
    • SMG (honestly I'd rather wait for a console which can render these games REALLY well like in 4K with cool shaders etc., the potential for beautification this game has is unreal)​
  • RPG / 3D platform hybrid​
  • Donkey Kong RPG​
  • More 3D Donkey Kong games​
  • Mario Kart with better rosters​
  • Mario RPG Party​
 
A proper new Mario Kart (i.e. not a simplified micro-transaction filled mobile game or port). Something that combines some of the best parts of each of the other games and sorts out some of the issues, and has a decent roster with minimal clones.
 
Mario & Luigi: Double Dimensions, it would basically take the concept of Paper Jam but actually use characters specific to Mario & Luigi and Paper Mario.

Basically, if Paper Jam had come during the GCN/Wii/DS era, before a certain 2012 game came along and set a standard of Mario RPGs being nauseatingly sterile.
 
I still doubt it would have turned out the way you'd wanted it to.
 
A Super Mario platformer with the Mario side of the Mario Party characters (based on how Super Mario Party categorise them) being playable. The more playable characters, the merrier.

Although perhaps a more unpopular idea, I would love to see another Mario character have a game starring game, provided that they haven't had a game starring them yet, so for example, Daisy and Waluigi.

Thank you for reading.
