NOTE ON THIS REVIEW: I listened to two episodes at the beginning, one later on, and then spotchecked more recent episodes to test my initial thoughts.
If you're looking for a fully designed experience within an actual play, this is one of the best I've heard. Their design is well thought out and immersive, and consistent throughout the entire piece. This crew has also been going for a while so they really know what they're doing in later episodes. They've ironed out the kinks, and are really in their form as performers and storytellers at this point.
For me, the sound design is too much. The mixing makes the background noise overtake the vocals pretty often and I struggle to track the story. The music is often drowning out vocals as now. It made the listening experience hard for me. The background design also highlights the difference in audio recording between performers. The quality of the production makes any audio issues stand out like a sore thumb, in a way that less sound design tends to forgive. The early episodes (like so many podcasts) have audio issues early on that can make tracking the show hard, and it's hit or miss how many have been solved in more recent episodes. Some of the recordings are significantly improved which make the listening experience much more positive. However it's not a consistent increase across the whole cast.
All of that being said, while I'm not sure that this podcast is my cup of tea from an actual play perspective, a lot of that is personal preference. For this style of actual play, this is absolutely at or near the top of the class, and I highly recommend trying them out.
