Nintendo released a little web page where you can view some of your Switch play stats for the year. Kinda neat! Yours are probably more interesting than mine. https://switch.nintendo.com/year-in-review/
Here's mine (You can export the individual things as images but it's less detailed so I'm doing a whole page screengrab)
187 hours and 11 games played, but they messed up the ones I played the most. Somehow, the four hours I put into Wargroove counted more than the twenty-five I put into Let's Go, Pikachu! Ys VIII and Super Kirby Clash were the top two games played in front of that.
I'm pretty sure their calculation for the most played games by hours is wrong. I was suspicious when it said I played more Yoshi's Crafted World than Mario 3D All-Stars because there's no way getting 100% in Yoshi took longer than 100% in all the Mario games, which included doing Galaxy twice (once as Mario and once as Luigi). I checked on my Switch and sure enough, I have 20 hours in Yoshi and 45 hours in Mario. So I have no idea how they're calculating that number and I'm suspicious of all these other numbers now too.
I think the overall total's right, but they did mess up my individual games order last year by putting Wargroove (4 hours) over Super Kirby Clash (30+ at the time). This year didn't have any mistakes for mine, but that doesn't mean it's glitch-free for everyone.
