Games in my library that can be played using just one hand

Any story or turn based games. Maybe something else ( ͡° ͜ʖ ͡°)
Some RTS games on easy.

I know that feel bro, already had two (small accidents) where I couldn't use my hand for a short time and couldn't ride my bike.
Hope you will get better soon

One Finger Death Punch

Life is Strange

You can play Paradox Interactive games with one hand easy. And it seems you own at least Crusader Kings 2.

Pretty much everyone has given you a ton of suggestions already, so you should be set there.

I do want to say that I will send good vibes your way that this is only temporary and you regain full usage of your hand! :(

Bayonetta.

Not a game, but some games may become one handed if you get the right kind of mouse? Mine has a ton of buttons, and the num/thumb-pad would probably work well enough as a d-pad, given enough practice, I would think.

Obvious: One finger death punch

you should play deponia but too bad u dont have the next 3 stories they are great

but replay it again try to do it 100% :) since u have time

... Clicker heros!

Jokes aside,
Soul gambler, (I kind of actually enjoyed it)
This War of Mine
SEGA Mega Drive & Genesis Classics
Abzu? (I believe you steer with the mouse)

As I havn't checked your whole library close enough heres some games/Genres you might enjoy:
Telltale games, (easy to manage)
Visiual Novels
Point n' click / Hogs

You could try to use the numpad, as it's close to the mouse, might work for some more games then?

From the games that you haven't played yet.
For sure: Back to the Future: The Game, Life is Strange, Sam & Max, Terra Lander, Secret of Monkey Island, All the Tropico games, Wallace & Grommit
I'm guessing Cities XL too.
Legend of Grimrock may be a possibility, if you mess around with the key binds.
I figure Dear Esther is slow enough for someone to be able to play it with one hand, keyboard only. Not sure though, never actually played it myself.
Maybe Divine Divinity and Beyond Divinity. It's been a long time since I've played those.

Get well soon!

You mean THAT games? =)
Well, I play Euro Truck Simulator 2 on keyboard usually no problem with one hand.
Also vote for Civilization 5 and ANNO 1404 (but I don't know if you have it).

View attached image.

Sakura clicker

Hm, let's see:
The X-com series (not including interceptor or Enforcer)
Wallace & Gromit
Trauma
Star Wars: Rebellion
Puzzle Agent series
Post Mortem
Hector
Back to the Future
Age of Wonders series
Sam & Max series
Broken Sword series (can't speak for the games after 2 though)
Skyward Collapse
The Journey Down series
Warlock: Master of the Arcane
Civilization series
Shadowrun Series
Syberia series
Bionic Dues

Scribblenauts Unlimited has an ingame keyboard you should be able to use.

Another vote for XCOM, CIV and Shadowrun games.

I'm i'm not mistaken, crusader kings and europa universalis and... well, all of those paradox games.

Point and click games are for you too.

Hope you get well soon.

Also Kotor 1 and 2 can be played with one hand, although you may be swtiching WASD to mouse more than once.

Well, almost every strategy game...

Hope you will get better soon

Heroes of Might and Magic, maybe? III or IV (yea, I know, people says 4th sucks, but it was my first HoMM game so I like it)
King's Bounty (may be hard on a global map, but it's worth to try)
XCOM/X-COM/Xenonauts (not sure about last one - haven't played it yet)
Don't Starve
Endless Space (maybe Endless Legend too)
Sins of a Solar Empire (there is a pause here and game speed settings)
This War of Mine
Symphony (mouse is more than enough for it)
Red Alert 2/C&C Tiberian Sun/Firestorm (you may have problems with squad ctrl+# bindings)

Also, maybe, classic Fallout games (I don't actually remember if they need 2 hands to play, sorry).

Hope you'll get well soon)))

Edit: sorry, missed part about your library =(

That really sucks... hope you get well soon.

I recommend One Finger Death Punch.

And you have a bunch of strategy and RPG games that are turn based (Shadowrun, Civilization V, This War of Mine, King's Bounty, Bloodbowl, Crusader Kings 2 could also be an option although it is stoppable real time...).

Good luck!

An AWESOME game that I can't recommend enough is Desktop Dungeons. Could be played only with the mouse.
