I have been reading the Mothership Warden’s Manual over the last week, the “DMG” for Mothership. I find a lot of dungeon master’s guides fall short. People manage to run D&D in spite of its rulebooks, not because of them. Mothership’s Warden Guide is superlative because it breaks down how to get the game you just bought to the table: it understands why these game master books should exist in the first place. There are very few books that pull this off well.
