Outward.
Nothing like going on a journey with your pal.
Being able to chat with someone on the road makes the travel time in the game way more bearable and coordinating your attacks against a strong monster is awesome.

Alien Syndrome, particularly the Wii version with 4 players onscreen simultaneously.

^This, great memories.

I would go for Rayman Origins. Also Rayman Legends must be added on GOG ASAP! If we are talking about games that are not on GOG then I would suggest these games: It Takes Two, A Way Out, Castle Crashers and BattleBlock Theater.

My pick is TOWERFALL:ASCENSION. It is designed as a co-op party game for up to 4 players. Players battle each other or team up in quest mode. Lots of fun, easy to get into, and challenging gameplay. Party On with this great archery battle game. You can pick it up right here on GOG!

My humble recommendation: "Door Kickers: Action Squad".

Game of two heroes. Each one a cop
With guns of might. It's a great coop.
And IMO this game has its own unique magic.

BTW It's the best coop game my brother and I have played recently.

Due to the fact I am a huge fan of RPGs I would have to suggest one that so far (I think) has not been said by anyone else,
Arcanum: Of Steamworks and Magick Obscura. A non linear, fantasy RPG. I'm also pretty sure that the co op has a smaller but different stroy to the singleplayer.

I've always loved a co-op game, from Robotron 2064 on the BBC Micro (one player controlling movement, one shooting) right through to Ghost of Tsushima on the Playstation 5. There are great co-op experiences to be had in any game genre, whether it's a fully-supported co-op mode in the game or one person controlling while the other shouts encouragement. With screen sharing, the obstacles to co-op play have come down, so there's no reason not give it a try.

My recommendations from the games currently available on GOG would be:

Proper co-op:

* Divinity: Original Sin - Enhanced Edition
* Trine Enchanted Edition
* Overcooked: Gourmet Edition
* Octodad: Dadliest Catch

Limited co-op:

* ARMA: Gold Edition
* Neverwinter Nights: Enhanced Edition

Single-player, but great to play together:

* The Secret of Monkey Island: Special Edition
* The Walking Dead: Season One
* Unavowed
* The Wolf Among Us

Cuphead has to be one of the most enjoyable coop games i've played. Especially being able to revive my friend and keep the fight going. We might spend more time revivng each other than we do fighting the bosses but we're laughing the whole way through.

Deep Rock Galactic. For Karl!

I'd recommend Magicka 2, but you asked for coop games... ;)
Jokes aside, it's a blast once you get used to the controls and the writing is quite funny.

Alternatively, seeing as we are nearing Halloween, I'd consider Dead Island, Don't Starve Together or even Dark Souls/Bloodborne (, if you dare).

Heroes of Might & Magic 3 works fine as a co-op game ;)

How about Baldurs Gate 3, Divinity : Original sin 1 & 2 or perhaps.... Obviously Heroes Of Might And Magic 2 through 7...

Thanks for the giveaway !

For a coop game I would recommend Divinity Original sin 2, a very good game, interesting plot but not all of big text and a sense of liberty to chose which perks you want !
