I just got my copy of Fantasy Craft. As I've been reading the book and preparing and converting my now ex-pathfinder campaign I have an important question. Do I need the Adventure Companion or any other wooks to run the game properly? Also, is there any errata I need to keep in mind that correct or clearify the second printing? Also, as the only one with a copy of the book, until my players decide to purchase their own, I will be the sole source of material.
