My nearly 12 DS loves Monopoly. There is a version called Monopoly Empire that plays a lot simpler and faster that we play in our RV when we're on the road. At camp this past summer he was crazy for a game called Hive that we haven't bought for home yet. Another good one is Catan, which is pretty simple at the surface, but it can get really strategic. We also like Wits and Wagers, Scrabble, Bananagrams, chess, Sorry, Trouble, and Connect Four. And he has resurrected Operation as a quickie when he wants to stall at bedtime.
