In Castle Panic, all players work together to kill off monsters before they destroy the castle in the middle of the board. It's very easy to learn and play, but difficult to win! Last Saturday we had six players and I thought for sure we would win, but sadly we did not.
I think this game would work really well for families with children of all ages. I think all six of us adults had fun playing it as well though. There is a variation where one player actually controls the monsters. I think it would be great fun for that one player, but don't see how he would ever lose.
This is the only co-op game I have. It's a very light game, but pretty fun. Below is a short video explaining how to play.
