How about digging in drawers & closets & toy boxes and pulling out all those old games that have been mouldering away?
Start a Battle of the Games* with family and friends to decide on a few favorites to keep. Then donate the rest to a local homeless shelters to keep people, especially the kids, making the best of a sucky situation.
*Battle of the Games pits two games against each other. You play two random or similarly themed ones back to back. Then everyone votes on which was their favorite. That one gets set aside to be played again. The other gets voted on for a second chance or to be put in the donate box right away.
Good bonus rule: play for a few rounds, until everyone has the hang of a game, then have a quick thumbs up or down to decide if you should keep playing. Don't waste time on stuff no one likes; there are TONS of great games out there, so don't suffer with duds.
