I've always thought that Peach should become playable as a reward for rescuing her.
That is actually how they did it in Super Mario Run. I never got to play as her though; I didn't cough up the $10.
I've been playing a LOT of Super Mario Maker 2 recently. Especially since the Super World update came out, I've been working a lot on that. I've also played a lot of Multiplayer Versus, which is... an experience.
I've recently gotten back into Tetris 99, and I'm as bad as when I left.
I've played a decent amount of NSMBUD. I've gotten about halfway through the game. I have a separate co-op file with my brother, who is not a good sport, let's say. I've also been trying to get gold medals on the challenges. Everyone says the New Soup games are too easy, but those challenges are extremely difficult, especially if you're going for gold.
And, I suppose I should mention this to cover all my bases... I've been playing some Fortnite, too. Listen, I'm not super into it or anything; I just find it fun. Most of the time...
