This is blatantly false. 3D World has a run button which no other 3D mario game has. 3D World has powerups that no other 3D Mario game has ever had. 3D World is about as getting from point A to point B as fast as possible with as many collectibles as possible. Sunshine was about collecting stars at your own pace.
Comparing it to Sunshine is especially absurd since Sunshine has a pretty unique controls scheme with the water gun unlike anything in any other Mario game.
Again, if you want me to take an argument seriously it has to first not be straight up false.

I gotcha.
So Sonic Adventure, Mario Sunshine, Sly Cooper, Ratchet and Clank, Crash, Jak and Banjo all play the same using this logic.
Now that we know this is your entire point here are we done?
If you're going to reply at least let me know all these games that Splatoon copied. Still waiting on that.
