You will benefit from this book if you are a practitioner of the art of serious wargaming. Done well, the simple act of putting players in an immersive environment, asking them to make decisions and then face the consequences of those in a dynamically evolving narrative generates astounding insights and internalises learning objectives. Yet, as Clausewitz said of war, everything in wargaming is simple, but doing the simplest thing is difficult. This book explains the seemingly simple. It is a detailed guide to designing and delivering successful wargames, whether you apply the technique to Defence, other government departments, business, the emergency services, academia or humanitarian operations. This is important because good wargames save money but, first and foremost, they save lives.
