Videogame-themed podcast Gamer's Tavern had Chris Avellone as a special guest for its 48th episode, and rather than going for the usual interview, had Chris talk about the Fallout pen and paper campaign he ran at Interplay as part of the pre-production on the cancelled project Van Buren. As I'm sure most of people that would be visiting this site know, Van Buren was the codename for Interplay's internally developed Fallout 3, before the property was sold to Bethesda. There's a lot of good stuff in there that is, as far as I know, completely new. For example, Avellone talks about Van Buren's Elijah, an ex-Brotherhood of Steel companion that left the faction to join the Cipher, and that would serve as the basis for Fallout: New Vegas' DLC antagonist. Additionally, he elaborates on the original idea behind Caesar's Legion, a largely capitalistic corporate-inspired slaver army without the Roman theme of the J.E. Sawyer iteration, the idea to hire Bill Nighy as a voice actor (yes, really), and more. If you're interested in the history of the franchise and "what could have been" thought experiments, this is a really good (and long, given it's almost 2 hours of podcast) listen.
