According to Wikipedia,
Folklore is the expressive body of culture shared by a particular group of people; it encompasses the traditions common to that culture, subculture or group. These include oral traditions such as tales, proverbs and jokes. They include material culture, ranging from traditional building styles to handmade toys common to the group. Folklore also includes customary lore, the forms and rituals of celebrations such as Christmas and weddings, folk dances and initiation rites. Each one of these, either singly or in combination, is considered a folklore artifact.
Sounds like your game fits the definition of folklore. :)
