This book contains six major adventure systems, all of which are designed to be expandable, either increasing in complexity and variety or changing to completely different scenarios as the systems grow.

In an adventure game, the player takes on the role of a warrior, explorer or mage and ventures forth into a different world presented by the computer. Adventure games are different to most other computer games because they offer a choice of strategies.

The chapters for each system are divided into a number of secctions. First is an overall introduction to the system, its scope and the way it expands. Next comes the initial program (the "core" program) which is at the centre of the system; here instructions and explanations are given.

The six systems are Present Fantasy, Warrior Mage System, Tribe, Preset Future System, Fangmole Tunnels System and Anarchic System.
