I really can't write a review for this product that weighs heavily enough on how fantastic it truly is. In each carefully detailed section, it is absolutely clear that this is is a labor of love.
Sunfall is well written, to the degree that I often wish it were a novel and not just a Genesys RPG supplement. It has all the makings of an edge-of-your-seat page turner, the world and its inhabitants being highly detailed and interconnected. Anastasia's writing inspires drama and great storytelling.
As an RPG supplement however, this translates into world-building tools and setting lore that will fully immerse your players, as well as a fair example for how to create the same in your own settings. Sunfall is absolutely packed with unique new material: gripping adventure seeds, clever and thematic game mechanics (Rules for intraparty conflict, secrets, and possession? Yes, please!!), and a stunning array of new careers, magic, talents, and adversaries.
Whether you're looking for a truly unique setting in which to run games, or for inspiriation and tools for building your own, you will not be disappointed by what Sunfall brings to the table (see what I did there? ;).
