Cooperative Games? I think we could use some of those. I just read quite a post about them over at Imagination Soup which is a lovely blog for parents.
I'm inspired by the family who makes these games and their desire to create a more helpful and less ruthless society around them starting at home. What a brilliant concept. The name of their company is Family Pastimes. Ages seem to range from 3 to adult, and it looks like there are multi-age games.
Amazon has their games if you don't want to order from Canada (shipping issues I suppose).
