When in doubt, Human Fall Flat never fails lol

I don't know how many players will be playing the co-op game so I'll list 3 games and choose my favorite.

These two games are nice co-ops, if it is allowed to play games out of the store catalogue:
For the King (up to 3 players) - I rarely enjoy co-op games but this one kept me interested for a fair while. I highly recommend this.
The Forest (up to 8 players) - I'll be honest, I have not spent too much time with this one but still it is one game I can recommend for co-op.

From the GOG catalogue, I'll go with Icewind Dale! You can't beat good old FRP vibes you can get from this game.

So from these three, I'll go with For The King if there will be 3 players at most.

Super Mario Galaxy. Where the cool child plays as Mario and the disappointment collects the star doohickeys.

Walk the Streets of Rage 4 old school beat-em up nostalgia!

Pandemic, the board game.

You and your friends need to stop a deadly pandemic spreading over the globe. It's hard. It will take cooperation, planning, and intelligence to succeed.

The viruses are highly infectious and will do their best to spread despite your best efforts. Random circumstance -- modeled in the game as event cards with various effects -- will either help or hinder your efforts. Maybe you will draw "One Quiet Night", which skips some infections, or maybe you will draw an epidemic card, which increases both the number and the rate of infections.

Again, cooperation is key; losing the game feels bad, and winning it feels so good.

Regardless of who wins this contest, please consider pressing more than one copy of that vinyl disc (including the covers), and offering them for sale. I'm sure it's not just me who immediately thought "must have!" upon seeing that.

This thread is full of great recommendations!

Has to be Risk of Rain!

Permanent death is a feature best shared with friends.

Oh come on guys - these are all nice suggestions, but the truth is, that if you want to have a few drinks and many laughs with your friends, the best game you can play is Mario Party 1, 2 or 3. Trust me, been there, done that :)

Heroes of Might and Magic III

Divinity Original Sin 2 is fantastic. You can go the murder hobo route or be a saint and both options are valid ways of playing.

Come on, guys! This is for the party! I know just the game...

Super Smash Bros. Ultimate!

Or any smash game really. You get to beat on up to 8 of your friends and coworkers in intense and colorful battles. If someone gets tired, they can hand the controller to someone else. More often than not, everyone wants to get a chance to play!

Maybe you could switch to a more relaxing game towards the end of the event, but one thing's for sure. You definitely need to start the party with this game! I usually play till my thumbs hurt and I know I'm not the only one hahaha.

Happy Anniversary GOG! Stay safe and have fun! Thanks for being you

Please make it happen GOG

Well, damn... I really don't play coop games that much (other than running through SWTOR with my nephews, anyway), so this is actually quite a tricky question. Does playing Baldur's Gate on multiplayer count? Or for a game better suited for it due to the lack of a designated protagonist, Icewind Dale.

Freespace 2 with FreeSpaceopen Extension.

Play with 8 People via LAN in COOP flying two Wings of Bombers or Fighters !
