I'm not thrilled to see so many Mario Kart Tour maps here. But am ecstatic to see a brand new course!

Did a lap of the new lap with the new character, it was fun.

The Questyen

They announced the 4 characters for Wave 6 that comes out later this year: Diddy Kong, Funky Kong, Pauline, and Peachette. Nice additions in my opinion. They also reiterated it as the final wave so leads to believe that this might actually be it for DLC. Rumors were that they might announce more waves to cover all the Tour tracks since that is shutting down but looks unlikely now.

Michael Corvin

They should keep it going until every course is in game. Just make this the Master Chief Collection of Mario Kart.

This is probably my least favorite MK but the dlc maps have definitely helped win me over some and I would continue to buy.

The Questyen

Yeah I see people clamoring for a MK9 but I don't really see what additions/changes they could make that would necessitate a new game. Most previous MK games changes were due to massive graphic jumps or Nintendo controller changes. Whereas a Switch 2 is almost certainly just going to have slightly better graphics and no massive change to the way the system controls. I'd much rather they just use this as a hub and continue adding classic tracks along with new track/character DLC.
