I really enjoyed Moon Hunters.

It Takes Two was absolutely excellent, but only two of you could play at once.

Castle Crashers.

TowerFall Ascension although you may already have this from one of the itch.io charity bundles (I know I’m great for accidentally rebuying things)

I honestly cannot suggest Overcooked if your kids suck at games or you’re an asshole (I end up like Gordon Ramsey in Overcooked, and thus am not allowed to play Overcooked).
