Really like this guide. It's extremely comprehensive.
Future Press has a different (and for me, much better) approach to game strategy guides. In short, the guide is designed and written in a manner that allows the reader to decide how much information - help they want.
So you get the guidance you desire coupled with the amount of "figure it out yourself" you want. If you want all the answers to getting through the game, you have it; if you prefer mastering the game through your own wits, with the occasional assist when you're truly stuck, you have that also, specific guidance without unnecessary spoilers
I purchased from Sierra Nevada Books. Book was in superb condition, exactly as described.
