We played a new game with friends last weekend called DiscomBOBulation. Lots of fun, we had ages 12 and up but I think it would be good for as young as 9 or 10.
Once we had one round under our belts, the next were a lot easier to understand. The game had us all laughing.
I am looking to pick it up for my family as a gift.
Others we like are Balderdash, Scene It, and Apples to Apples. My brother keeps recommending we get Settlers of Katan, which is a game played by our friends as well. They love it.
