Updates will be made to this online edition as I get the time to do it. In early 2001, I had the Third Edition of the Wargames Handbook published in paperback. The major changes are in the chapters covering professional wargames. I put this edition out for a number of reasons. Military schools still like to use the book as a textbook.
Many people also like to have a hard copy version around.
Moreover, Internet users outside the United States, where local calls cost a penny or two a minute, find it expensive to stay online for too long.
