This is a fairly good book, but is rather thin for the price. It seems targeted to the Intermediate Civ2 player -- anyone who is looking to refing winning high-level play strategy will find it rather redundant.
However, if you are struggling at King or Emperor level, this book will help you. It's targeted to building a sound empire, then winning (albiet sloppily) at Emperor and Diety levels; however, it will not help with most of the more subtle play at those levels (e.g., getting your score from 3,000 to 15,000 by 1850 AD, etc.).
This book does discuss solid fundamentals, how to deal with unhappiness, how to start a strong empire, etc. It does not cover things such as the OCC (one city challenge), getting your top Diety score above 20,000, and the game's more subtle idiosyncracies (max advances, the food caravan 'trick', cheapest way to rush build, etc.).
The cutting edge strategies still reside on the Internet, or maybe you'll discover them during extended gameplay.
PS, If you still seek a challenge, take the OCC (though this book does not help). OCC game rules are simple: you are only allowed ONE--that's right--ONE city, no cheating, no takebacks (unless a hut gives you a city); game setup: Diety level, small world, 7 civs, raging hordes. Your single city against the world... Top players can LAND a spaceship by 1900 AD, and the best have done it before 1850... Questions? My email is civII@bigfoot.com
