Brilliant!
The strengths of the show is based on the closeness and friendship of the cast, their chemistry together, and most of all, their extensive history of comedy improv allowing them to roll with the punches and not step on each other's toes.
They bring their comedy flavorings, so they are a delight to listen too.
Dave's adventure he is putting them on is, so far, interesting, has strong narrative legs, and is engaging. The edits are immersive, but simple enough not too distract.
And at roughly 1 hour a pop, biweekly (as oppose to weekly 3+ hours, like my DM's sessions) easy to fit into a busy schedule.
Even if you don't know DnD, you should still be able to enjoy their antics. I highly recommend this to anyone, not just fans of DnD or Mischief.
