The GM Showcase & StoryArk Podcasts

I highly recommend both!

Story Ark is great to inspire ideas, but also just entertaining purely as a listener. I suspect more variety in content-but with the same polished delivery is on the way!

GM Showcase is entertaining, and serves as a good example of how games can flow, game pacing, balance rules vs story etc
the first few eps highlight the gaming skills and styles of some of the DMB Usual suspects

also I use the GM Showcase as a benchmark to aspire to-for recording and producing my own D&D sessions

Wish List : I hope with GM Showcase they get former GM's to return say 6-12 months later, do another game to either continue the old story, or do a different part of the world, or a different style/genre in their game.
