A really nice find over at Playing at the World, I had no idea this existed.
EDIT: Just finished listening to it. Really it’s highlights punctuated by analysis from Jon Peterson, which actually makes it even more interesting in my mind. That said, the actual action of the radio show is about the best presentation of D&D play of anything from the era in my opinion. It’s a shame it didn’t catch on, and instead we ended up with stuff like the D&D cartoon and a terrible series of movies.
