Definitely Factorio but he careful if you have anything important upcoming that requires adequate amounts of sleep.

Oof, not currently on sale surprisingly. But still worth $35.

Untitled goose game, It takes Two and Portal 2 were very fun in local coop. Did not know divinity had local coop thanks!

I am bookmarking this post to come back to later. I've gotten my partner into video games and we like playing local multiplayer, specifically co-op.

Our favourites are: Overcooked and Stardew Valley (Nintendo Switch version has split screen).

Ones we enjoy are: ibb & obb, Jumpjet Rex, Shutshimi, Spiritfarer.

Every single Overcooked game is on sale, and they inspired half the local multiplayer games that are coming out these days.

Rain World is also on sale, and co-op is a blast. As much as playing Rain World can be, I mean.

Cuphead, also, but everyone knows about that one.

It Takes Two - one of the rare two-player splitscreen co-op games on the market. And an amazing game as well - play it with your best friend or SO, get laughs, maybe even feels, and a super fun experience! Can also be played online, and only one player needs to buy it.

For online gaming, the We Were Here series is a finely crafted quartet of 2 player co-op puzzle games. The first installment is actually free to play on PC, so you can give a try if you enjoy the concept. Later games have much higher quality though, and so far every subsequent game has more or less doubled in length, and each one can be played twice as you can change the roles for each puzzle!

Resident Evil 5, Cuphead and The King of Fighters are some of my Favorites

Duck Game is good and straightforward fun. Would totally recommend.

Nidhogg is worthwhile too. Really quick to learn, works good tournament style so that one can grab another beer every now and then.

Gang Beasts and Human Fall Flat are honorable mentions. Super goofy, might want to be accompanied with weed, not only with beer.

Overcooked. Really makes you think about the phrase “too many cooks in the kitchen.”

Lovers in a Dangerous Space-time while too baked or on shrooms is a top tier experience.

I like beat em ups like river city girls and streets of rage 4
