I for one would like to congratulate the latest 2D Mario game on being almost as interesting as Kirby Triple Deluxe, which isn't even the high bar among modern Kirby games.
Having playable Peach, Daisy and Yoshi is a good start that at least brings it up to 3D World's standards, but I'll only be impressed if it pulls a Kirby Star Allies and goes to town with the roster. Rosalina. Birdo. Nabbit. Pauline. Diddy Kong. ROB from Mario Kart DS.
