Gagmen RPG Podcast is about designing adventures and each episode (or sometimes two episodes) results in a PDF of the scenario created by the podcast crew.
from the Gagmen website
Welcome to Gagmen! In our Podcasts, we take an adventure pitch, discuss the various elements of the module, including the plot, setting, theme, characters, and conflict. We then produce a finished adventure PDF, available for download, to give the busy DM plenty of material to create or customize their own adventures.
