This is a great little side system that is light weight and can add a bit of depth to the world you're weaving for your players. Anyone who has used 5E's piety system (introduced in Mythic Odysseys of Theros) will Factions 1's system immediately familiar and intuitive. Moreover, a number of generic and specific example factions are presented that can either be slotted into your own game or used as scaffolding for your own unique faction tracks. Definitely recommend this splat, especially at this price point, for any medium to long running game.
