If you're looking to "decolonize" D&D, move away from strict racial-trait systems or are just looking for another way to customize characters in your setting, this is a bloody good way to do it. The authors have meticulously curated all of the racial traits from each playable race in the current 5E environment (including PHB, Volo's, Ravnica, Eberron and MTOF) and developed a solid method of creating highly customizable characters using a variety of selectable "inheritances" rather than requiring every character of every race to have the same immutable traits. They also decouple stat bonuses from racial traits and provide means of tying them to classes or backgrounds instead. All this results in a much more diverse method of character design. Highly recommended, and something that could serve as a good foundation for future editions of the game.
