Most games have GMs whose job is to keep continuity and provide creative friction while the players are the primary decision makers. This makes for tricky scheduling problems, because you need both the people who maintain continuity and the people who drive the story to show up!
The Grimoire has it where the player drives the story and keeps continuity, which means that a single, sufficiently motivated person can keep the game going, even if the rest of the group is in constant flux! And the Grimoire itself handily provides that motivation, because I sure as hell want to figure out what is in it!
