Okay, so this is not my first Numenera-centric podcast, so if this would be for you, give it a few episodes to get the lay of the land. Like, three/four I would say. Then go back and listen for actual content then you're good to go. But basically, while you can catch up on the Numenera lore/world rather easily. The DM and cast use it very well and in somewhat critical ways. They all play well, and they know their game well. Which makes for a unique experience in a sea of Actual Play podcasts, but it's does reward you for taking time to get to know it from the get-go.
