My high school did this. They hauled me and my friends in front of one of the deans because we’d been playing chess in the lunch room, and they said that if they let us play chess, they’d have to let the other students play dominos, and when they play dominos, they gamble, and when they gamble, fights break out, and there weren’t enough security guards to handle that. So no chess. We pointed out that we were the school chess team, but they were unmoved on the topic.

It was really dumb.

We talked a bit about the possibility of having a couple of our better players play mental chess, that is, no board or pieces to look at, and just yell moves back and forth across the lunch room while the rest of us loudly gambled on the outcome, but we never actually did it.

I should preface this by saying I don’t actually have a steam deck yet, so I haven’t tested these on there. So I’m only commenting on the games themselves. These are listed as deck “verified” in the steam store, though.

One I haven’t seen mentioned yet is Yoku’s Island Express. Breezy summer vibes, not much difficulty. It’s kind of a pinball metroidvania.

Tinykin is another game with a very cozy/low stakes feel. It’s an exploration/collectathon platformer with cute environments made up of household objects.

Littlewood is a life sim sort of game, kind of like Stardew Valley, but it’s extremely chill. There’s no time limit or anything like that.

And others have mentioned these, but Toem, Alba, and Donut County are all very good and gentle games too.

Oh, and Tchia. That one has some dark moments at times, mostly in cutscenes, but when you’re actually playing it’s mostly gentle and island-y.

Maybe also Wuppo? It’s a strange one. The story and humor and animation are pretty great in that one, but there are some boss fights that can get a little frustrating. It’s mostly a fairly chill platformer, but then it’s got kind of bullet-hell-adjacent bosses. I still really like the game, but it’s not quite as purely relaxing as some of the others here.

Pikuniku is kind of in the same position as Wuppo, but I liked it a bit less. The humor feels a little more forced or stilted, and the frustrating bits are because the controls are kinda floaty. My niece really liked it when she was 8, though, so it had that going for it.

Hope this helps! I’ve been looking for this kind of game a lot the past few years

I dunno, I think you may be underestimating ARM here. I’ve heard that the overhead from translating the machine code is a lot lower than you might think, because so much X86 code is optimized down to a RISC-like subset of the instruction set already. And if that overhead isn’t too daunting in the common cases, the more robust power management on the ARM side of the chip market might be able to make up the difference in a handheld environment for most users. Obviously it’s a huge amount of work to nail the software, and it would be on top of the work they were already doing on Linux, so I’m not saying it’ll definitely be in the next iteration, but I could definitely imagine it happening eventually.
