Look at how GMs in Real-Play RPG podcasts go about presenting their long-term narratives. Do they present a sandbox world and let the players improvise? Do they railroad to hit more traditional story beats for the listeners? What’s most effective?
It think also you need to discuss the background work of the GM from a narrative standpoint. For example, looking at what those GMs have identified themselves as preparation and development - do they use modules or write their own? do they create NPCs or build these off predeveloped characters? Also looking at the framework of their game could be interesting - how did they select the current narrative? was it in conjunction with players? had they run this before? There are many different avenues to explore. – SaraiMW3 years ago
