Beyond the podcast itself, I find this cool for two reasons: 1. you landed Brad for the podcast and 2. Brad was willing to do it. Pretty neat imo.
And I just thought it was neat because the guys doing the interview clearly knew the subject matter, so they're asking quite specific questions directly about the games/gameplay... instead of some high level type stuff.
Sometimes you can listen to an hour long podcast/interview on a game, and not learn anything new because the discussion is just about all the info that is already published. Not the case here because it got into quite a bit of detail on various subjects. Helped by Brad's rather open approach to discussing things, so yep good stuff.
