Have you Discworld fans played the Ankh-Morpork board game
? My husband and I have been obsessed with it for a couple of months. I haven't read the books, but he has, and it seems great for both of us. It's really easy to learn because each person plays a character from the city who has his or her own secret victory conditions. So, one person will be trying to get, like, 50 gold pieces, and another person will be trying to get the deck of cards to run out, etc. The more people playing, the more chaotic it gets, which I guess mirrors the books. Also, the art is beautiful and funny.
(If you click on the link and look at the rating, know that users at BoardGameGeek are so stingy that an 8/10 is like a perfect score. The top rated game on the site has an 8.231.)
Oh, hey, while I was gone I got real into board games.
