Hello, we have many years the basic game and love it and it in turn gave away in the family. Now I recommended someone above expansion and we got a problem! Our basic game is very old and made of wood, the new is cool and made of plastic. We bought it anyway and put us all out of wood. Regardless, an expensive business, which more than worth it. After some initial minor difficulties - Reading and understanding and reacting - our enthusiasm rose steadily and we sort the new elements do not even get out, because the game is so awesome cities and knights, for our 10th twins that we no longer play without well be. The city expansions and especially the barbarians bring a great fun factor, the additional cards, which unfortunately have a different back when our old ones. We find also a solution for. I highly recommend it. Even my little game muffle is blown away. I think for SETTLERS OF CATAN fans it is a must, but making yourselves your opinion.
