This is one of the best purchases I've made for my roleplay! I have used elements from this book in every one of my campaigns, as both a player and DM. I can't overstate how useful it is. There's such a wealth of information packed into the pages, I use is about as much as TCoE or XGtE. I only wish there was a hardcover version of it. I'd love to get my hands on a physical copy.

Let me offer an example of how I use this book I have a PC wizard who started out as lawful evil, basically Ayn Rand with a spellbook(intended as a character flaw). They were just as much about business as they were adventuring. This character started out investing, buying properties and starting new businesses during downtime. By level 10, I was keeping a spreadsheet to track all the passive income. The party started investing in infrastructure and social programs to build their reputation and good will. My character also found a few love interests and moved into a cottagecore style house with them. Now they're working on a chain of book stores, one for each romantic partner. This became my retirement plan for that PC.

This book will give you what you put into it but the possibilities seem endless. It's really opened my eyes to a new level of roleplay.
