It's 100% the same game. But it runs slightly worse.

It also runs at a slightly lower resolution, but that shouldn't impact your experience much, if any. It's still one of the greatest games ever made---on Wii U or Switch!

I appreciate both versions of the game however i prefer the Wii U version a bit more for a few reason, despite it running at a lower resolution than Switch and suffering some slow down here and there. There is a subtle diffrence in the games colour pallet on Wii U that i prefer.

atari i think thats just your tv output settings on your switch , change the rgb range to limited and see how that goes
