You mean we won’t have to buy ewaste electronics to play Mario Kart? Sign me up.
Realistically though, I’d bet on a “Mario Kart Mushroom Kingdom Racing” release (or something) that would just be a cross platform live service.
… and honestly I’ll take that any day over Nintendo, which I’ve given $0 in over a decade because I refuse to buy their ewaste. I would love to have their games on PC though.
