Well, for this one I don’t have an answer. I have so little free time as it is that I can rarely find time to listen to anything of any length and I don’t have the memory to be able to pause and come back later. I also don’t really like listening to things like talk shows or audiobooks when driving as I tend to find them distracting (it’s why I tend not to listen to the radio either, unless it’s very heavy on the music and light on speaking).
Consequently, that leaves me a little light on options for this one.
However, there is an RPG podcast-y thing I have enjoyed and listened to a number of times. Numenera: The Signal, is an in-universe, in-character series of transmissions of strange rumours and reports by Vaux, an Informed Jack that Tells Tales. It is done very well and is actually usable directly in-game during a session due to the way it’s presented. I encourage you to check it out.
