We met in a hotel near the Messe in Essen, and while avoiding the hackneyed "theme vs. mechanism" question that seems to plague every designer interview, I tried to take a broader approach to the topic of game design, how Knizia's approach to it has changed over time, what constitutes failure in a design, and what might come from him in the future.
I've watched only part of the edited interview due to my aversion to watching myself, but that experience has already provided me learning material for future interviews. Ideally this video provides something worthwhile for you, too!
