Portal 2 co-op could be good

Playing a solo game with a controller, taking turn and discussing what to do is actually really enjoyable too. You then have a lot more options. I would recommend subnautica or outer wilds

Off the top fave co-ops:

• Overcooked
• Divinity original sin series. BG3 also
• Cult of The Lamb
• KeyWe

There's probably more but that's what I got immediately

Stardew Valley has split-screen co-op with controller support.

Get you an emulator and play Seiken Densetsu 3 on SNES, also Secret of Mana, Goof Troop (I'm serious), play some classic Dynasty Warriors, really most Musou games fit your bill, Samurai Warriors, Warriors Orochi, Capcom's Sengoku Basara, Zelda Hyrule Warriors 1 + 2. Which reminds me, get you Dolphin emulator and play you some good Gauntlet Legends Dark Legacy on Gamecube. There are whole slews of this stuff in old libraries that I can't think of at this immediate moment.

BG3, obviously.

It Takes Two is a lot of fun, and all the games from that same dev. I think they did A Way Out and a few more.

Until Dawn, all the "Dark Pictures Anthology" games, and The Quarry, if they like spooky stuff

https://store.steampowered.com/app/330020/Children_of_Morta/ has local coop and is pretty easy to pick up, it's reminiscent of Gauntlet.

And like Soros mentioned if you don't mind playing old games it's super easy to fire up an emulator, Zombies Ate My Neighbors, Pocky and Rocky and Secret of Mana all have coop off the top of my head.

Heavenly Bodies. You play astronauts on a space station doing menial tasks, but the difficulty is that you have to control all your limbs properly to move around in zero-g. It's tricky (has easier modes tho) but is really satisfying when you learn how to work together to fling screwdrivers around.

Core keeper was just released Yesterday. It's really fun and it really shines when playing with more people.

Bread and fred to truly test the relationship.

Rainworld has local coop although i think its locked behind the downpour dlc. Then you can be slug cats

House of ashes and the quarry are good fun. The ending sequence in house of ashes sits quite highly in my list of brilliant game moments.

If you want to go the emulation route, most arcade games play very well with a controller. Get yourself a frontend for MAME and make your life easier.

Operation : Tango is a really good coop game and little known game. Besides, the asymetric nature of it means it has replay value.

It takes two is great as well.

Trine 2, puzzle sidescrolling game with 3 characters (wizard, thief, knight) with different abilities that need to work together. You can play by yourself and swap between characters at any time or play co op it's quite cute and fun

Same PC, or coop on separate PCs with controller support?

Guild Wars 2. You need an addin for controller, but it's great for couples

Lovers in a Dangerous Spacetime is a cute game about piloting a spaceship together. The catch is that there are more than two stations that need to be operated so you have to coordinate running around the ship, jumping from station to station. It's a lot less stressful than Overcooked

Human fall flat! Very simple, funny ragdoll physics, puzzles, co operative, low pressure... It's such a great co op game for non gamers. It's got built in controller support too. Not very heavy PC requirement either.

Gang Beasts is similar but a bit more chaotic. I don't think it's as good.

Once you get the hang of it, pop some tunes on or chat away to your heart's content while your brain puts your hands on autopilot.

I'll second Portal 2 co op.

Any of the LEGO games too, if you like Star Wars/LOTR/Pirates/Indiana Jones or whatever other franchises they've done. To me, the older ones are the most charming.

Shootaz Blood n' Teef

It's like Metal Slug, but with space orks! Also, there are Metal Slug games for PC.

At first, I misread you as asking for 'cop games'. I thought that was incredibly specific.

my partner and i are currently playing baldur's gate 3 together and its pretty fun. i am pretty sure you can do split screen, but we're playing it with her pc hooked up to the tv, and me on the steam deck.

Why hello there fellow gf haver

Resident Evil 5 is good fun

Rayman legends is great for coop.

Unravel one and two were fun platformers, if a bit short. You'll need a bit of coordination and precision to pull off the tricks necessary, but nothing too fancy.

Also on SNES: Pocky and Rocky

Haven't seen Bokura, KarmaZoo or Chicory mentioned yet. Nidhogg is local VS not local coop, but still quite a bit of fun, especially if one of you hasn't played much more of the game than the other.

Okay all of these are likely going to need you to set up an emulator for them, as that's where most of my co-op game experience lies.

• Baldur's Gate: Dark Alliance
• Baldur's Gate: Dark Alliance II
• Champions of Norrath
• Champions Return to Arms
• Ratchet Deadlocked
• ~~Crash Bash~~
• Halo MCC on PC (However doing local coop requires this mod, I have no idea why they stripped out that feature on PC)
