An excellent companion to the Players guide, compiling a large amount of information on the Known Worlds, along with the GM material from the core book from the previous edition. The layout is also great, and has fortunately been applied to the Players Guide.

It’s a great book! If you bought the revised players guide it becomes a must have if you plan on running the game. It fills the gaps that the players guide had and includes all of the Imperial Survey books for the noble houses and the imperial worlds. That right there makes it worth its price. It also includes NPC's, rules for poisons and drugs, a list of creatures that you can run into, and a sample drama. With this book and the Revised Players Guide you have access to pretty much everything you will need to play/run the game.
