From the Introduction:
"In 1990, the first Final Fantasy game saw an American release and in the eleven years since, the Final Fantasy has remained one of the best selling role-playing games for each of the console game systems that it has graced. This pen & paper roleplaying game, the Returner Final Fantasy RPG (often abbreviated as Returner FFRPG or just FFRPG), was designed to emulate the popular game series and similar titles from the "SNES era" such as Secret of
Mana and Chrono Trigger. The Introduction includes the editor’s words of ‘wisdom’: From the Mouth of a Madman, the revision history that lists all the
important changes made, a brief explanation on what a role-playing game is, how to roll dice (the fine art of chugging dice), and the glossary of Final Fantasy RPG terminology."
