I would love a Mario Kart on Xbox Live.
That would be awesome.
I still like Nintendos first party games, even though I feel to old for most of them now.
It is just that Nintendo missed so many trends when it comes to technology (HD Gaming, Online Gaming, Digital Distribution, (4k) - BluRay, VR, etc.) so they will never see 3rd party support like Playstation or Xbox.
They act like kickass specs mean no innovation. That is just wrong.
Imagine not having GamePass on your console...
