Powersharks – A variation of War. Not very interesting but Little I can play with the older kids if they help him the (few) times math skills are needed.
Waterworks – Bought the classic version. Good clean fun.

My wife’s family had the dutch edition for that, with carton wrenches, and they used to play the heck out of it. Very recently we picked up an english/american edition, which was, I think, the re-issue for the 25, or 40 year celebration? But this one had the bathtub, and “real metal” wrenches. And it’s still a great game!
