My game (I am the DM) is set in the Byzantine empire, early 800s AD. From Constantinople the parties (eventually most of the parties took Constantinople as their ultimate operating base - there is a Byzantine Party, an African Party, and an Asian Party- I have three separate parties playing) move and travel outwards into the Empire, into Western Europe, into Eastern and Northern Africa, and into Asia Minor and Asia to adventure, or on mission assignment.
The milieu is real world and historical, but underneath that is a fantasy mythological world that most people never see, but which the parties encounter.
So real world and historical political, military, cultural, Imperial, technological, religious, languages (like Greek, Latin, Persian, Frankish, etc.) and ethnic forces are in play, but the players also encounter a sort of secret or covert world in which magic and monsters and things like that also exist.
So I guess you could say that the players in my various parties, and I, are both pro-historical (modified of course by the underlying covert magic and monsters and otherworldly aspects) and pro-myth, folklore, etc.
But I notice from the polls results, derived of course from those who actually voted (that doesn't mean this is the general consensus but it is certainly the consensus of those voting) that mythology and folklore and those kinds of things are very, very popular in many games.
I think the game designers would be wise to understand this phenomenon, and what it implies, in developing their overall game theory and how the game might best be expressed in the future.
