The JRPG of Final Fantasy 15 is a mammoth, cultured nation, ruled by Chocobo with an iron fist, and renowned for its frequent executions, keen interest in outer space, and enforced nudity. The hard-nosed, cynical, humorless, devout population of 8.55 billion Final Fantasy 15ians are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The large, corrupt, moralistic, well-organized government juggles the competing demands of Law & Order, Defense, and Administration. It meets to discuss matters of state in the capital city of Square. The average income tax rate is 67.1%, and even higher for the wealthy.

The frighteningly efficient Final Fantasy 15ian economy, worth 788 trillion pounds a year, is led by the Automobile Manufacturing industry, with major contributions from Uranium Mining, Retail, and Book Publishing. Black market activity is notable. State-owned companies are reasonably common. Average income is 92,243 pounds, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Sniffer dogs are trained to follow clouds of fruity-smelling vapor, the explosive fireball of the disintegrating space shuttle has devastated Cape Final Fantasy 15, drivers regularly pull over for nonexistent police cars, and diaper-wrapped falafel is a fan-favorite. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Final Fantasy 15's national animal is the panther, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Crystals.

Final Fantasy 15 is ranked 44,264^th in the world and 3^rd in Square Enix for Most Advanced Defense Forces, scoring 6,128.52 on the Total War Preparedness Rating.
