So far, Mighty Peach looks to be my favorite.
This morning I downloaded a demo of Princess Peach Showtime to my Switch and played it. Looks and plays about what I expected it to. Reminds me of something you'd see on the GameCube, but that's NOT a bad thing! You could play as Swordfighter Peach in a action platform level and Patisserie Peach which lets you play a few Cooking Mama style mini-games. The Swordfighter level was pretty easy, but the cooking level was surprisingly challenging! At any rate, I'll be getting this game when it comes out March 22.
