Even though I have a much shorter commute than I used to, I still enjoy listening to some great audio podcasts, specifically some gaming podcasts.
Rebel.fm is fun, with a few guys who answer gaming and relationship questions (NSFW).
Weekend Confirmed, with Shacknews’ Garnett Lee and Brian Lahey and Jeff Canatta from The Totally Rad Show. Long, in-depth and passionate.
Player One Podcast with a bunch of guys from various backgrounds, lots of in-jokes abound.
A Life Well Wasted. Robert Ashley’s fusion of stories about gaming culture and remixed rad music. Very occasional, but worth it.
Brainy Gamer. Michael Abbot assembles great game designers and creators for roundtable discussions on games.
