I say kill it with fire..... Mario is big enough that it deserves AAA levels of effort.
Go make a new Oddessey instead, or another new 3D mario.
I grew up on 2D mario games too, so it hurts to say it, but mario has moved beyound 2D, and does so well enough, I dont think there needs to be any 2D games in the series.
