First off you need the basic SAVAGE WORLDS to play this game. The book does a good job of updating the Deadlands franchise keeping some of the original content yet blending it with the Savage Worlds model. By the way, you should like Savage Worlds (which has several similarities to Deadlands like dice exploding, poker initiative, etc) or this game won't fly for you. Think of the Wild West with a twist in History and then toss in steampunk, horror, monsters and all types of Western cliches.
I really like the poker method for initiative, the poker chips (which are like the Fate/Action Points in other games), the dueling, and, of course, the world of Deadlands, especially the extended American Civil War as I'm a big time enthusiast. Deadlands purists may not like this as its condensed down into one hardback (the original Deadlands was books upon books).
