This tome is so evocative with its setting, a crazy amount of art, and wagons (wagons!), it's an absolute joy. The first nine chapters describe a colourful world to play in, filled with 200+ pages of interesting places, faces, and potential story hooks... and it's pretty much system-agnostic, too (a plus for me!). This sets up a pretty ripe sandbox that incentivises travelling to interesting locales and delving in dangerous places. Chapters 10-13 (species, classes, wagons, magic items/spells) are more 5e specific, but even then they're filled with lovely things to use with your system of choice.
Whether you play 5e or not, if you like anthropomorphic animals, a colourful sandbox-friendly setting, and wagons (wagons!), do pick this up!
