Unravel 2 :) It's a beautiful little co-op game with lots of puzzle-y problems to solve and some dynamic ones as well

Lovers in a Dangerous Space Time

Manage your malfunctioning space ship together while fending off waves of enemies.

Very fun.

Spelunky 1 & 2

Monster Prom, Monster Camp, Monster Roadtrip

Also seconding Kingdom: Two Crowns

My gf is pretty new to video games but these are a few she enjoyed

Trine 2/3

Snippets

Castle crashers

Unravelled

Diablo 3

Children of morta - my gf also doesn’t really like pixel art but this turned out to be one of her favourite games

We just started the spiritfarer. Absolutely worth it

Broaden your horizons, start using emulators.

Star Wars: Jedi Power Battles

Kirby and the Forgotten Land

Super Mario Wonder

Any of the Warriors games (just don't buy it, don't reward them for releasing the same damn game 20+ times)

Legend of Mana (highly recommended, please don't sleep on this)

Destroy All Humans 2

Ratchet: Deadlocked

Divinity: Original Sin

Resident Evil 6

Halo: Master Chief Collection

Lego Star Wars

The Tales games are long and go up to 4 players. I'd recommend them if you have more people to join.

Be prepared for a few roadbumps while you acclimate yourself to using emulators. It won't be smooth at first, but it gets easier the more familiar you become with it.

If you're open to doing emulation, there's a multitude of Nintendo games that are amazing couch co-op.

• A Hat in Time
• Trine
• Spiritfarer
• The lego games
• Knights and bikes
• Human fall flat
• Cassette beasts
• Chariot
• Octodad
• Monaco

I don't remember these being particularly violent but maybe are worth a look:

• Pit people
• BattleBlock Theater

I also liked Moon Hunters and Children of Morta but those are harder.

Divinity Original Sin 1 is also good but definitely falls into the violent category. Its kind of goofy too so it could be worth considering. The second game + BG3 are significantly more violent and serious so are harder to recommend with that criteria.

Edit: hmm it seems the formatting is funky in Voyager, should be fixed now

I'm not even a huge platformer guy, but Rayman Legends is absolute peak and a fantastic, chill co-op game. The music levels in particular - where the already great soundtrack is synced in time to your jumps and hits - are incredibly satisfying and so well made.

I'd also be remiss if I didn't suggest Blue Prince. It's not co-op per se as it'd only be one person at a time "driving", but the game is about puzzle solving so who holds the controller doesn't really matter. It's a fantastic game if you enjoy puzzles and escape rooms. My sister isn't even a gamer at all but I recommended it to her fiancé and they've been playing together and even she's been enjoying it a lot. From my own experience playing it on my own I also think it would be much more fun if playing alongside someone else. I've often missed having someone to bounce ideas off when stuck.

... Genital Jousting.

Death Squared. Puzzle solving, each player controls two blocks on the map used to solve the puzzle.

I’m a fan of taking turns “driving” for slower paced logic or puzzle games. Titles that come to mind:

• Myst
• Curse of the Golden Idol
• Summertime Madness
• Chants of Sennar
• Superliminal
• Viewfinder
• Baba is You

I can highly recommend all of these as they almost universally benefit from more minds working on them together. I would say Baba is the only one that gets REALLY challenging, but there are good mind and logic bending puzzles throughout them all!

EDIT: I’ll also add that Myst, Golden Idol, and Chants of Sennar (Summertime Madness maybe a little) all benefit from solid note taking and map making This provides a great job for the “copilot” while the other person is managing the actual input device.

Check out Kingdom Two Crowns. Absolutely brilliant

One of my favorite games to play with my SO is Out of Space the vibe is very similar to Overcooked but it's procedurally generated and a lot more chilled out, i.e. less chaos.

Keep talking and nobody explodes could be a fun one, only needs 1 device and the other player needs the manual which can be on a phone or printed out. You could even play it over a phone call.

If you enjoy escape rooms try out Escape Academy, haven't seen anyone mention it but it's really a blast!

Me and the wife played a few coop games.

• DERU - The Art of Cooperation is a pretty puzzle game that is satisfying, not too difficult nor does it overstay its welcome.
• We also enjoyed the snake-esque puzzler OmoTomO. Only on itch, not Steam, so you have to install it via the desktop mode. When you're willing to dig a bit itch grants you some shiny gold nuggets for cheap.
• In Lovers in a Dangerous Spacetime you have to run around a spaceship to operate the different parts (engine, guns, shield). More straightforward than it sounds, and the pacing is such that you're not rushed but do get some tense moments.
• Almost forgot Pode which is a very cute 3rd person puzzle adventure game.

Some games recommended by other people in the thread that we can corroborate

• Trine series is good platforming fun with pretty graphics and dialog that is a little on the nose sometimes.
• Kingdom: Two Crowns is good for a few hours at least, can't say I cared about beating it because the levels just keep coming with only minor variations. Definitely a unique blend of tower defense and base building.

Personally I agree on Overcooked, once the novelty wears off it gets a bit frustrating because of the difficulty. Its still fun in groups though.

A few options me and my partner have enjoyed:

Bunhouse - a non-management-heavy farming simulator but you are bunnies growing plants. Cute as hell. There is a sequel where you run a bakery too but we haven't got round to that just yet.

Unrailed - might fall into the overcooked catagory, but when it gets hard and goes wrong it tends to be a looming inevitablity, not a frantic panic

Nidhogg - a 1v1 fighter, but is quick fire frantic sword fights you can button bash through which is wildly entertaining in 5 min bursts.

The cult of the lamb

Degrees of Seperation - 2D puzzler with wonderful scenes and visuals

Heavenly Bodies - 2D puzzler about astronauts and 0 gravity environments

Unrailed - isometric 3D. A train starts driving and you need to gather resources and build tracks etc.

Wobbly Life - 3D fun game, no real objective, just many quests and activities throughout the world

A way out. Two criminals escaping prison, made by the Same studio as it takes two and split fiction. Full of mini games along the way like the other two and my god the story made me laugh with it's ridiculousness. it's definitely not as good as it takes two or split fiction but well worth a go imo

A bunch of retro games have good couch co-op support & the steam deck can emulate pretty much all of them

Zombies ate my neighbors, smash TV, 2-d brawlers like TMNT turtles in time, double dragon, and streets of rage, Goldeneye, toejam and Earl, bubble bobble
