for local coop of course portal and as a bonus, kid safe, - it takes two, biped.

I'm currently playing V Rising right now with my wife after Divinity 2. We are LOVING it. Definitely give it a try!

Torchlight 2 and 3 are fun looting co-op experiences.

Check out Larian's other masterpiece, Divinity: Original Sin II. Original Sin I is great as well, but a little dated.

Stardew Valley has really good multiplayer now. Might scratch some of that Minecraft and Terraria itch.

Elden Ring with the Seamless Coop mod looks like great fun if you enjoy that type of game. I've wanted to try it for a long time.

Pikmin 3

Overcooked

Subnautica can be played together using the Nitrox mod

Can't believe I hadn't seen anyone mention "it takes two" great game, was free on Gamepass when I last played it.

I’m playing through BG3 with a good friend too, we’re actually planning on doing another, wildly different, playthrough when we’re done with this one. We’re playing sorta chaotic/neutral good right now and intend to do an evil campaign next with different characters and classes and possibly even modded.

Now I obviously haven’t tried it yet but the game has so much hidden stuff, branching paths and different-to-play classes I’m fairly confident you can play it at least twice and have an almost entirely new experience!

Most of these have been mentioned before, but I'll mention them again.

Halo Master Chief Collection. Everything before 5 is local split screen. 5 requires two Xboxs. I would just avoid Infinite, but I believe it also requires two systems, maybe including PC.

Diablo 3 is very accessible. 4 should be as well. I'm told Diablo 2 is the best, so I need to try to get back into it. All should be good options.

Monster Hunter requires more patience. At least for World, cooperation is good but really the game is geared towards individuals being able to take charge as necessary. Track, set traps, bait, capture, etc. Multiplayer is VERY useful during fights though.

Stranger of Paradise is kinda Souls-like but more forgiving. In my experience it's A LOT more friendly to Multiplayer. It's also a ton of fun with a friend.

Psi-Ops: Mindgate Conspiracy. An old PS2 game. One person controls the body, the other controls the mind. Especially if you have a Gameshark and you can go Godmode.

Any of the old Street sports games were a blast back in the day.

Older Twisted Metal for another old-school recommendation.

Gauntlet

Assuming Steam?

• Halo, obviously. Master Chief Collection is pretty cheap to pick up these days, don't miss out on the Halo 3 ODST DLC.

• Ready Or Not can be a challenge with just two people, but it is very rewarding to get a good score.

• Zero Hour is very similar to Ready Or Not, but it has different features and I find it a bit easier.

• Deep Rock Galactic

• Risk of Rain 2

• Elden Ring (Seamless Coop Mod is highly recommended)

• Monster Hunter World (include Iceborn DLC)

• Generation Zero

• Project Zomboid (if you like this one you'll probably sink hundreds of hours into it)

• theHunter Call of the Wild (chill hunting shooter)

• Farming Simulator 2019 (new ones may be better, haven't researched)

• Barotrauma

• Factorio

• Elite Dangerous

• Green Hell

• The Forest

• Sons of the Forest

• Morrowind has an OpenMW fork that supports multiplayer, if you get it set up this can be a fun game to play

I believe the entirety of the Gears of War series has a co op mode

Also if you don't know anything about the series like I did before playing Gears 5 with my kids, don't play it with kids....

Warframe

Grounded

Grab a PS2 emulator and give Kuri Kuri Mix a go.

It's by FromSoft of all people and it seems hardly anyone has heard of it.

If you don’t mind horror games, the entire Dark Pictures Anthology and The Quarry are really fun shared stories with branching paths.

As of last week, Cult of the Lamb

For crafting/exploration/survival I'd recommend Valheim. Don't judge it by its looks, the game is insanely fun with friends.

The "We Were Here" series is a fun puzzle co-op game. The first one's free if you want to try before you buy.

Steam link

If you're into souls-likes, try "Stranger of Paradise"

Its fantastic, nobody has heard of it for some reason. I played this last year with a friend and it was really fun (if you're into that playstyle)

Darksiders Genesis was also very fun with my little cousin, more hack n slash, one player gets to be pure meelee and the other half meelee half twin stick ranged.

Sniper Elite (4?) is pretty good as a chill co op FPS mission progression game.

Otherwise, probably any survival craft will do, you already played a few. I enjoyed Valheim and Planet Crafter and wish Subnautica had Multiplayer.

Popping in to suggest Ship of Fools and Cult of the Lamb

Ship of Fools was shorter than I'd like but lots of fun. Currently playing through Cult of the Lamb co-op and and we've been having a blast

Rayman Legends.

Nine Parchments - Top down Magic slinging romp. Similar to the Majica series, but with less knowing how to do certain key-press combos.

Orcs Must Die 2 - 3rd person tower defense where you place traps and use spells and weapons to take down foes. Continues the story of the first game, which did not have multiplayer, unfortunately.

Children of Morta - Top down dungeon crawler. Take on the roles of a family trying to hunt down an ancient evil. Like the Belmont's of Castlevania fame.

Full Metal Furies - Top down action fighter. Fight the Titans as some of the last remaining survivors of Ragnarok. Fun dialing with a good-sized world map to explore.

Astroneer - 3rd person survival crafting on a randomized planet. Cute component designs and a unique air management system. Plays best with a mouse & keyboard.

Deep Rock Galactic - Space Dwarves Corporate mining simulator. You and up to 4 friends drive do into infested planetoids in order to make some Gold. Destructible terrain and shenanigans.

Cat quest 2 if you like cat puns and something casual. (Cat quest 1 is single player and doesn't (really) connect to the storyline of the sequel)

It's an old game, but Pixel Junk: Monsters is a ton of fun as a co-op tower defense. Don't bother with the sequel - s'bad.

It's a very different experience, but have you considered Baldur's Gate 2?

PlateUp can be fun in 2 player co-op. If you've played Overcooked, its basically a clone of that, but turned into a roguelike. Its not the longest or deepest, but its still solid, and the price is very fair IMO, esspecially if you get it on sale.

The Division 2 is fantastic co-op and often gets put on sale.

Not played most of the games you mentioned so not sure this'll be your thing, but I've gotten back in to Sky: Children of the Light recently and it's been great.

It's beautiful, f2p (ad free!!!) on a bunch of different platforms, and going in as a pair will give you a head start since it has a social aspect and is designed to occasionally get players to cooperate (though you can play alone just fine, I do most of the time and cooperate with and befriend other platers). It's mostly chill and you can take it at your own pace and make what you want of the world - follow the spirit guides and play through "proper" or fly/run/swim around and discover things on your own. You can use skills like playing instruments and taking photos, decorate your own or shared spaces, customise your character, chat to people from all over, or just chill in your favourite spot.
