Fucking hell, are you okay?

Edit: Also Syberia is a good game. It’s point and click.

Point and click visual novels.

Can’t do the steam deck.

You can, as long as the game works based on touch input only.

So games like Civ 5, Shadowrun, Slay The Spire, Mini Metro should be fine.

The Civ games are great one handed as they are turn based. Civ 5 and 6 are what kept me sane when I broke my hand just before COVID lockdown

Like others said, any turn-based game. Currently suffering enjoying SMT III Nocturne, others I’ve played are Octopath, Fire Emblem, Pokemon (esp Mystery Dungeon), Atlus in general. Balatro sounds nice. Rhythm heaven is WarioWare + Music, and that’s definitely doable one-handed, especially the Wii version. My mom said Fortune Street (Monopoly but Mario + Dragon Quest) lol.

Mobile games can be very doable, a cute one I remember is Candies n’ Curses, a game where you swipe to direct the character around a haunted mansion and fight bosses. Easily can be played with one hand. If you can tolerate gachas, Cookie Run Kingdom can be put on auto so you don’t have to tap much, I just like the story and characters. I think Geometry dash can be doable on low levels with one hand?

Find your inner weeabo and play some Japanese visual novels. Or if you’re a normal person then Ace Attorney would be a fantastic choice, and is a long-ass series. Prepare for courtroom bullshit and jokes.

if they are still active the mmo’s champions online and star trek online are tab targeting and even allow for some scripting. I actually had posted on reddit that I would like for people with disabilities to know about them. the right builds can be done with input every so often that does not need to be split second (some roles do require a bit more timing but if its just one handed its toatlly doable)

Anything on PC with a mouse/keyboard, maybe with the spacebar remapped.

• 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.

One Finger Death Punch

XCom

Or I guess anything with keyboard/mouse.

Welcome to the club! I did the same thing with a meat slicer about 20 years ago. My thumb was flat at the tip of the nail for a long time, but it’s grown back since then.

Turn based games are great for one handed, because you can take your time hitting the buttons. Maybe slay the spire, Inscryption or balatro if you haven’t tried those yet.

Pokémon Let’s Go [Eevee / Pikachu] can be played with a single joycon vertical in one hand. They designed it to be played with their Pokéball controller, accidentally making it super accessible.
