Been playing Mario Odyssey every day since release and having an absolute blast. I was never that big of a Mario fan aside from the Mario Kart series, but I'm blown away by how much I'm playing this one.
Before Mario Odyssey I was set on BotW being my personal GotY but now with Mario, I don't know. Both games are so amazing and it's hard to me to fond major flaws. I'd be nitpicking. I'll wait til I get to post game Mario and see which I like better. Once I beat Zelda I really hadn't no desire to go back into it for Korok seeds or shrines, despite how absolutely terrific the 70+ hours I put into my play through. Will see if Mario post-game will keep me playing after beating it story.
So personally for me, these 2 games alone have made my Switch purchase feel like a no brainer. There have been some other games in between I've played here and there like Binding of Isaac, Mario Kart 8 Deluxe, Puyo Puyo Tetris, and I still have Steamworld Dig 2 that's on the back burner til I finish Mario but the next big game is Xenoblade Chronicles 2 in December. If that's as good as I hope, this first year of Switch is gonna be godly.
But one side effect that I didn't see with the Switch, is that my GF took to a couple games and basically took ownership of my Switch for a couple games. I bought Picross for her since she's into Sudoku on her iPhone, and I thought maybe she'd like to try out a similar game. Oh man, once she learned how to play it I didn't get my Switch back until like a week later when Mario came out. I checked my play logs, she put 45+ hours into Picross! I laughed out loud when I saw that. She also took to Puyo Puyo Tetris before that as well. So that's pretty awesome so far.
