Interview with Alf Seegert, designer of Trollhalla and The Road to Canterbury:

“Don’t be afraid to find design influences OUTSIDE of board games. Often the best ideas do not come from games at all!”

“Recently I’ve followed Elton John’s rule: if the song doesn’t write itself quickly, don’t bother. Development can take months (or even years) but if the basic idea doesn’t come together quickly, I move along.”
