Here's what the Pulpgamer site had to say about the interview: Don’s trip to Games Expo in Las Vegas rewarded him with a visit with Klaus and Guido Teuber. After the exhibition hall closed down on Monday we sat in the Mayfair Games booth and talked about their game designing experience and their quality visit in the U.S.. The strength in their family really shines through in the interview as well as the great games they have developed together. Catan has had a significant impact on board games, rivaling the old classics and making its way into homes across the world. It is stretching now into various electronic mediums such as the one mentioned in this show. If you haven’t made your way to playing this game the time is right to catch up with us.
