World of Darkness
The setting of Vampire, Werewolf, Mage, and several other games; the World of Darkness is essentially the modern world if everywhere was Detroit. By very deliberate action, the world has slowly become stultified, and warfare, unrest, and unhappiness are endemic. The US is a modern day Rome – the privileged lead lives of utter decadence, enhanced by access to magical and vampire-blood-enhanced drugs and elixers, while the downtrodden many are in a truly wretched state. The media, government, and most movers and shakers are subject to varying levels of control and manipulation from various groups, most especially the Vampires.
Buildings tend to favor the industrial age styles of the ‘thick concrete box’ aesthetic, and it tends to rain a lot (due to active efforts to poison the environment on the parts of various groups). It’s essentially a world seen through a darker lens, but not one completely divorced from the real.
