My most played games are Breath of the Wild, Animal Crossing New Horizons, Pokemon Violet, and now Tears of the Kingdom. And Mario Kart 8 Deluxe but I feel like that one's more of a multiplayer experience. Nothing else comes close to those on the Switch for me and I can recommend all of them.
Can you not access the battery in the Steam Deck? I haven't opened mine up before.
I also haven't opened the Switch before either though. Is it not possible to just swap out batteries like you could on the DS and 3DS? I had to swap out my 3DS's battery a couple years ago when it ballooned and always just assumed it was an option on the Switch too if it ever happens there.
Edit: Just took a look at the iFixit video, that's a much more involved process than I was expecting. Hate that they used adhesive on the battery, and didn't even add a pull tab to get it out.
Me too, but I hear it's bad for your enamel, so we shouldn't 😔
