#thefutureisnow: A 2010s-punk setting. It is the year 2114 and humanity as we know it is no more. Every single human child, at least in the developed world, is implanted with a backpack unit which contains a social media profile, telecommunications and Internet equipment and supplementary organs for surviving in the hostile environment. All communication is conducted through social media: romance without making it "Facebook official" is considered as lewd as prostitution would have been two hundred years prior, most day-to-day conversation is conducted with a 140 character limit, and if one does not have a social media profile, they do not legally exist. Geopolitically, the world is dominated by the Russian Union, the Asia Pacific Alliance, the European Union and the North American Union, who send legions of reprogrammed citizens into the eternal battlefields of Africa, the Middle East and South America to fight the primitive locals. These super-federations monitor their citizens closely, working in tandem with the great corporations to ensure that discontent from the various hacker resistance organizations never get too far ahead.
The End of History: A 1990s-punk setting. It is the year 2094, and humanity is interconnected like never before. The World Wide Web has eliminated paper and has made every home and office interconnected with every other. Most people spend their time on electronic media, such as the newest video game consoles from Sega and Nintendo. Cloning has brought back everything from the dinosaurs to the pharaohs. But as the 22nd century dawns, there is again fear of a third world war. The Russo-American Co-Dominium, which has dominated Earth for the 21st century, is being challenged by the European Federation, led by a resurgent Germany and opposed by the Krakow League of Poland, France and the UK. In the East, Red China threatens to upset CoDo dominance. The nigh-eternal sectarian violence in the Middle East, East Africa and the Balkans serves as a potential catalyst for this global conflict, although the Quebecois-Canadian confrontation can't end well.
Deader than Disco: A 1970s-punk setting. It is the year 2074, and humanity is still rebuilding from the Third World War. Slowly but surely, the irradiated remains of mankind pull themselves together, emerging from their hovels and domed cities. The world freezes under a new Ice Age from global cooling, but don't eat the snow: it's all toxic. In North America, ideological violence continues, as the feminist communes of the Pacific Northwest, the New Age "crusaders" of California and the industrial despotisms of the Midwest resist the expansion of the Christian Republic of Texas. The irradiated remains of Europe are fought between the communist dictatorships of the former West and the expansionist, Slavic-nationalist Sovereign Union. And in the East, the military dictatorships of SEATO continue their eternal struggle in Indochina against what remains of the People's Republic of China.
The Cavalier Centuries: It is the year 1918, and the Two Centuries' War has become the Three Centuries' War. Central Europe, still known as the Holy Roman Empire, is a blasted hellhole filled with medieval, plague-ridden peasants accosted by mercenaries and clockwork abominations. The great nations of Europe continue to pour their soldiers and machines into this hellish meatgrinder: neither the Sun King in Paris nor the Holy Roman Emperor in Vienna are willing to surrender and relinquish the victory their ancestors have struggled for. The British Isles are a fractured place, with the Royalist Kingdom of England and the Parliamentarian Protectorate of England stare each other down the London Wall, while the Scottish and Irish try to exploit the rivalry. In North America, the theocratic, Puritan Commonwealth of Massachusetts wages brushfire wars against the Native American states to the west, while ensuring that their internal reservation and segregation system does not cause the Commonwealth to tear apart. The Caribbean and Central America are the domain of pirates, who plunder Spanish and French ships attempting to bring more materiel to support their war effort on the European continent. In Asia, the declining Ming dynasty attempts to keep its satellite states from being wrenched away by Europeans, and the Tokugawa Shogunate maintains its strict isolation from the world.
