Andre Kruppa is an excellent GM with a great gleaming hoard of unique experience, and he's very generous with it in this book.
I'll be honest, I'm mostly too stubborn to take advice on my Game Mastering. Or lazy. I don't know. Either way, I tend to stumble along on my own and just deal with it if I find myself on an unfriendly path. Also, while I find the idea of using special lighting and other mood effects appealing in the abstract, I know that it will lose every last shred of that appeal as soon as those things move anywhere near the concrete. Heck, I don't even like miniatures. Even so, I found some useful tips for my games in here, stuff I will probably use.
Where this book really shines, though, is its practical advice on all that stuff that I don't do. If you have any interest in adding lighting, sound, and stuff like that to role-playing games, this is the book you want.
I guess that's it. If you really did read this review, I'm sorry. Your time would have been better spent earning back the paltry $3.95 it would have cost you to go ahead and buy the book on Amazon.
