Wargaming: An Introduction

This book introduces the hobby of miniatures wargaming, presenting the history of miniatures wargaming, how to collect and paint miniatures, and--taking up most of the book--simple yet (reasonably) realistic rules and army lists for a wide range of historical periods, from ancients to WW2, including special skirmish-level rules.

Its Ancient rules were later expanded into another full book:

Ancient & Medieval Wargaming

by the same author.
