Eric and Karen bought us the card game For Sale for Christmas. It's both simple and short. The game has 2 phases. The first uses a bidding mechanism to buy houses; the second uses a bluffing mechanism to sell them. The mechanics are simple enough that my 5 year old should be able to learn, but there's enough complexity to keep adults thinking. It looks to be both a great game for the whole family and for introducing non-gamer friends to the genre of German games.
