Some minor 6e leaks:
In 6E the role of Dungeon Master will be broken down into separate components enabling multiple people to engage in non-player activities. There will be a Dungeon Project Manager (DPM), a Dungeon Technician (DT), and a Dungeon Operations Executive (DOE).
The DPM is responsible for sourcing all assets, enemies, dungeons and setting materials for each session. These responsibilities will be carried out across a variety of digital and physical media, so a focus on game knowledge is crucial for this role. Whether the DPM creates any of these assets themself is entirely up to their discretion. With a divided DM workload, such a task has never been easier. However, given the massive amount of pre-constructed assets available for free (or for purchase), it may not even be necessary.
The DT is a simpler, foot-in-the-door sort of role for Dungeon Leadership. As DT, your primary responsibility will be to playtest and organize. Ensuring sessions occur regularly and on schedule without ruffling too many feathers is a delicate matter. Playtesting each session in mockups with the Player's character sheets will ensure the DPM has done their job appropriately. Key insights from this phase of Dungeon Production should determine the following: Did each Player Character get a Moment to Shine (MtS)? Did the skill checks/challenges provide an appropriate balance of tension and success? Will each player have roughly the same amount of speaking time over the course of the session? Lastly, were the rewards satisfying without causing balance issues? Compile notes and refer back to the DPM with any urgent issues or Dungeon Change Requests.
The DOE is sort of like the DM of olde, but without all that tedious prep and design work. Here you can focus on being a performer. Master of a thousand characters, both big and small. Instead of worrying about the intricacies of yet another dungeon crawl, dedicate that time to voice work and immersive characters to really make the session come alive. Immersion is your focus, and snacks are your secretary. If the DPM and DT have done their work correctly there will be few if any curve balls thrown your way. Instead of leaving a session up to the dice, you can finally invest yourself in the games plot without fear of abrupt changes.
