Kind of a smaller ones, but "Hanabi" and "Grizzled" are also nice. The good thing in these two games is they're not feeling like group solitaire (and I love a good game of Spirit Island, but point stands), you actually have to cooperate with another people, you can't win them by yourself.

And then there is Diplomacy, where you have to cooperate with everyone to get anywhere - right until you stab them in the back
