Kinda depends on what type of games you like!

Here's a few different ones: Timberborn, Slay the Spire, Darkest Dungeon, TemTem, FTL, Into the Breach

Edit: some personal favorites too: Dungeon Clawler and Ballionaire

Getting over it with Bennett Foddy.

It's a challenging but deeply emotional game. You only need to use the mouse to climb the character up.

Every game can be mouse only with an mmo-mouse

Maybe some classic, more phantastical CRPGs with turn-based combat are more your juice than Disco Elysium: Baldur's Gate III, Pillars of Eternity II, Fallout. Planescape Torment, Tyranny, Pathfinder, Pillars I and the rest of the Baldur's Gate series rely on real-time combat with pause which might get tedious when only using the mouse.

For point-and-click adventures, I've enjoyed the Samorost series, Machinarium, and Botanicula!

You can play osrs with just mouse, though keyboard shortcuts are handy/mandatory for late game - you won't be there though before the hand heals 😅

Peglin

Stardew valley with the mouse move mod /hj

Or bloons tower defence :3.. I've gotten a lot of gaming hours out of btd5

My random suggestions right now for stuff I like and is played with mouse would be:

• Rimworld. Almost any top-down PC management or (not too fast paced) strategy game should work, but, I really like the crazy random shit that happens to the characters you're slowly getting to know in Rimworld.

• Almost any of the Zachtronics games, if you like to torture your brain. Open-ended sort-of-engineering puzzles.The bigs ones like Spacechem, Opus Magnum and Shenzhen IO in particular, last call BBS for a bit more variety inside one game. Not Infinifactory, since while it doesn't have any kind of fast paced action it still requires navigating in 3D so mouse only wouldn't work.

I wonder if Bud Tucker in Double Trouble would still run. Probably would need dosbox

Anyway, whole adventure genre. Syberias, Mysts, Gabriel Knight

I've found Shadowrun trilogy fun

Darkest Dungeon, Oxygen not Included, Surviving Mars
Citizen Sleeper is short but well done, got me hooked to finish it in a single sitting
Arcanum I still consider one of the best RPGs ever made
Fallout 1&2

I don't know if Commandos style games would not require too fast clicking without a keyboard, but you could try out Shadow Tactics, it has active pause IIRC
Speaking of Commandos, Jagged Alliance was fun too

First of, sorry about your collarbone, that sucks

Second, I think if you're looking for something to disappear into I really recommend Baldurs Gate 3, I've seen it recommend here already but just wanted to second that, it's a really fantastic world to live in for a bit

Old School Runescape if you like grinding. But you might never quit if you get hooked :')

I'll throw in Oxygen Not Included.

Classics like The Incredible Machine and Ultima 8 come to mind.

The last two point and click games I've enjoyed were the Deponia series and the Book of Unwritten Tales. Both really good, challenging and fun :)

If you're a grand strategy fan: Crusader Kings 3. You could spend hundreds of hours in that game, and it's mainly designed to be played with only a mouse.

point & click adventure games? Some older ones can be aquired for cheap, or even free as some of them have been released as freeware.

some suggestions in no particular order, some are older (like, DOS old, but still good today, imo), some are 2010's or so:

• TellTale Sam & Max -episodic games (3d, cartoony, comedy)
• Monkey Island -series, parts 1-3. (2d, cartoony, comedy, pirates, yarharhar) (Later games in the series are pretty finicky to get running/stay running.)
• Sam & Max: Hit the road (2d, cartoony, comedy)
• The Dig (2d, scifi)
• Full Throttle (has a modernized remaster) (2d, "scifi", biker-theme)
• Flight of the Amazon Queen (freeware) (2d, ~40's vibe, "retro-scifi")
• Beneath a steel sky (freeware) (2d, scifi, comedy, some gore)

Ones that have some keyboard usage, but are mainly mouse driven (or can be mouse driven)

• Grim Fandango (modernised remaster, original doesn't do mouse) (3d, latin-american land of the dead, comedy)
• Indiana Jones & The Fate of Atlantis (some occasional fights where keyboard would be preferred, most of these can be circumvented though) (2d, some comedy, ww2, I mean, it's indiana jones)

The older ones can be played via Scummvm (https://scummvm.org/) - it's basically a simplified launcher/runner just for adventure games.

Get yourself Broken Sword Reforged and chill

Slay the spire

Backpack Battles! Fantastic little inventory management game with a load of replay value.

I'd say most RTS games I can think of can be played with just a mouse

Older diablo-like ARPGs didn't really rely on the keyboard too much IIRC, the modern ones do tend to rely on the keyboard a bit more

If you don't mind older games, basically the whole genre of point and click adventures is this by definition

Warcraft? Sid Meier's civilization?

Or in general any top down RPG game, like RuneScape.

Age of Empires, XCOM, Cities: Skylines, Divinity Original Sin 2, Starcraft, +1 for OSRS.

There is no game: wrong dimension

There might be some keyboard moments iirc but they’re not intense and you can let the mouse go iirc

This game needs more love

Nubbys Number Factory, addicting and mouse only.
