A fun Rogue Like game that lets you play as numerous different starting classes and do some absolutely nonsensical things. Has great co-op and is even more fun with friends. You can also be a gorilla

Cake Bash is a fun little dessert themed beat-em up with different modes. Some of the modes have strong Mario Party vibes in the best of ways. You can also bludgeon friends with a lollipop

PHOGS is a great co-op multiplayer puzzle game where you can see how quickly you can pull your co-op partner into the depths of despair by throwing yourself off a ledge. You can also bark a lot.

Gang beasts is a great party game that has been around for ages. I'm not the greatest, but I enjoy it every time I play it and it never fails to make me laugh.
