From the introduction:
Why play Living Jungle?
Enjoyable role-playing does not occur in a vacuum. You need a rich atmosphere and background to provide a foundation for your character’s personality. There should also be a logic, however subjective, to guide how the character reacts. Finally there should be a story that gives characters interesting goals to complete.
The Living Jungle has many of the elements necessary for great roleplaying. More than any other Living setting, the geography and peoples of the Living Jungle setting provide fertile material for players and authors alike to immerse themselves ina world rich with myth, culture, scenery, history, and wonder.
