I love Metal Mario, to me he's his own character and deserves a unique slot on rosters. If they do costumes for Mario Kart 9, I'm hoping they still make Metal Mario separate to regular Mario. It'd be weird not to at this point.
Pink Gold Peach and Gooigi are harder for me to figure out, I can...
Hoping it's new bosses, this game has the perfect reason as to why it's new bosses, and the Koopalings, sure they could go for another round but personally I feel like they've overstayed their introduction. Give it a break for a little.
I'm talking as in, every game's OST is bunched up together and you can only pick one from it. What's your most favourite?
If I had to choose, it'd be Dire Dire Docks.
