Beyond the specifics, I think the game needs to be narratively focused, but with significant consequences tied to that narrative. Hence the hyper mechanical nature of D&D feeling awkward and counter-productive. Similarly, I think the characters need to be tied into the larger events of the world from early on. When the characters are disconnected from the world at large, the games are aimless and the narrative less engaging. The best shows on Rollplay all did this from very early on in the game (Pi with Swan Song, Butt-touching with Mirrorshades, Evil Wizard Friend in original rollplay, god-baby in solum, and all the best west marches arcs were tied directly to big setting elements such as the serpents.)
DM: Very few DMs out there are capable of being super engaging while also managing the group smoothly during a very narratively focused game. You are one of them Adam, John is another, but there’s not a ton of these people out there. But, I don’t think this is a concern going forward, any new DMs are going to be held to your standards and will be good accordingly. Both of you are also good about making consequences fitting to the fiction in a fair manner, which is key.
Cast: The cast has to be comfortable getting into character quickly, and comfortable making the more interesting choices as opposed to the more optimal ones. Related: they need to be people with complementary styles. You need to avoid having four people who are more reserved and logical in their play, and in a similar way avoid having four people who like being silly and chaotic. Keeping that balance and having there be 4 people who play off each other is the hardest part. Sidenote: who the specific people are isn’t important, keeping someone off because there’s vocal people who hate kaitlyn is super dumb, make the group that gets along well as a group, and viewers follow.
Tech: The only thing I’d prefer to see is the inclusion of more audio work, possibly with a new theme song for every show (drumurboy pls <3333). Action music and more thematic backing tracks for certain things would be huge. Audio quality issues from people’s mics is already being fixed, so I don’t think it needs to be gone into.
System: You need to be using systems that support the above gameplay and interactions. D&D has no tools for interesting characters or interaction with the narrative, and similarly stars without numbers was very sparse in it’s help. Systems that support and facilitate this narrative and fiction-first focus will go a long way.
