When I was in high school, the sequel to my favorite game didn't get translated, so I convinced my parents to sign me up for Japanese lessons on the weekend. But I didn't get all that far in it on account of having too much actual schoolwork to keep up with.
Last year I picked it back up again, just for fun, and I'm making a lot more progress using Renshuu than I did in a classroom environment. Earlier this year I bought one volume each of a bunch of different manga series, slowly working through the pile with the help of vocab lists from LearnNatively and Wanikani. So far I've finished Yotsubato, RuriDragon, and Look Back.
Any of the Kirby games with multiplayer. Super Star, Dream Land 3, Return to Dream Land, Star Allies.
Nintendo has a couple of other games where P2 gets to be a helper, intended for younger players and non-gamers. Super Mario Odyssey, Luigi's Mansion 3, Donkey Kong Bananza, Pikmin 3/4.
Console manufacturers sell at a loss because they need to sell the console first before they can sell anything else. They can expect to make that money back on software the user could not have bought without the console.
Valve doesn't need people to buy Steam Machines to get them to start using Steam. In fact, I suspect most units sold will be to users who are already invested in the ecosystem. Selling at a loss would just be a straight loss to them.
Two years ago, one of my favorite games made some very minor cosmetic tweaks, and that was enough to attract a horde of post-Gamergaters crying that this is the downfall of western civilization. Two years later, the board for that game is still under seige by trolls that have rendered it unusable for anyone who actually wants to talk about the game. Every now and then a Valve mod will lock one thread, and then the trolls just make another and it continues.
I want to see The Year of the Linux Desktop™ as much as anyone else on this platform, but I think you're living in a bubble if you believe there's any universe in which this could suddenly dethrone Windows.
It'll carve out a good niche for itself, but that's really all it will be.
I don't think they even can manufacture at a scale anywhere close to the big three. Like with the Steam Deck, it'll be a great product for a niche audience, but the numbers will be limited in comparison. No chance of taking over the industry.
CoH's control scheme requires both hands, so I can't recommend it to OP. But I'll also have to say that I have the opposite opinion, CoH was good for a casual playthrough but wasn't something I could sink several hundred hours into like the original. The overworld made runs much longer and much more repetitive since a lot of it is always the same.
Anything turn-based, especially mouse-driven titles. Slay the Spire, Chess, Riichi Mahjong, Balatro, etc.
Puyo Puyo Champions has a one-handed preset in its controller options. Do note that if you want to play online, only Switch is active since that's where Japan is, I can't recommend the game on other platforms.
Kirby Air Ride uses only one button + analog stick, and any button works, so you can use L. Would have to be left hand for the original, but the sequel coming out later this month has a detailed accessibility menu, which I bet will include right-handed settings.
Crypt of the Necrodancer is designed to be playable with just four arrows, in case anyone wanted to play it on a DDR mat. Which also means you can play with arrow keys or WASD.
Rhythm Doctor is actually just one button.
Rhythm Heaven Fever uses only A and B. Rhythm Heaven DS uses only stylus. The rest of the series uses d-pad as well though, so those are less playable.
Come to think of it, any DS game that only uses stylus.
