I would disagree all Final Fantays have the same “culture” or the same type of society. There’s actually great diversity between the games…
Final Fantasy VII is a satire of America, with most of the different towns representing different aspects of American society. For instance, the Sector Slums are American urban ghettos; the Gold Saucer is Disney World; Cosmo Canyon represents American hippie culture; Korral, the poor working class; etc. And of course, there is the reference to the “pointless war” that Midgar fought with Wutai, an Asian country(does this scenario seem familiar to anyone)?
But most of all, the theme of a privileged, but complacent and apathetic middle-class living atop(in FF7’s case, literally living above on the upper plates) teeming ghettos is an explicit criticism of American society, as are the various diversions(Costa Del Sol, the Golden Saucer) that the people of FF7’s world partake in while the poverty-stricken suffer. Its no coincidence that the Golden Saucer - a metaphor for Disney World - literally exists above a garbage heap. Or that the people who work to support it, can’t afford themselves to visit it.
Final Fantasy VIII has a World War II look and feeling to it. Galbadia seems to have at least in part been based on WWII-era Germany, and Dollet and Timber closely resemble WWII era England/France, visually as well as thematically. Generally, FF8 doesn’t concern itself with societal criticism or examination as FF7 did, instead focusing on human relationships.
blah I ended up talking mostly about FFVII, but I’ll think of things for the other games later.
