I personally believe that Mario Kart Double Dash was the very best one. that awesome feature of picking two players and flipping between them was just so cool. I would hold different items with each and strategically use said items when the time was right but you could switch (*snap*) drivers to make sure which was holding what... why don't they make a mario Kart Switch that has this feature plus the gravity courses AND new elements? It can be called mario Kart switch I don't see why not lol
