Richard clearly has theme-first game design down pat, as he's able to tie back most questions asked of him to his art. He does some back-of-the-envelope math to demonstrate why a game will never be play-tested enough that really gives me something to consider any time I might put play-testing for a game into question. Oh, and if you're familiar with Arkham Horror, there's an excellent comparison of theme and mechanics to Eldritch Horror.
