I must admit, I am not the world's best RTS game player. I get beat quite often, and end up getting mad at the game, and retiring it to the shelf. However, with this guide, I was able to muddle my way through the Human Campaign, and got quite a good start on the Undead Campaign before Medal of Honor lured me away! What a dilema! My buddies team up against the computer at our LAN parties, and this book always accompanies me. One of my buds lives, breathes, talks, walks, and eats Warcraft, and HE found this book to be very helpful. Bottom line, if you want to do good at this game, or you are stuck or whatnot, get this book. You won't regret it.
