Just a look at the setting...
Earth & Solar System in the 22nd Century
For campaign setting we use
Transhuman Space, with but a few minor modifications (for example: France, UK, or Germany are not independent nations, but states of Europe, the same way Texas and California are states of the US).
Lets briefly describe the Solar system in 2108.
[Excerpts from the Transhuman Space book]
By the end of the 21st century, humanity is in the process of achieving two major endeavors. The first is to transform from a single, evolved species to a multitude of artificial races. The second is the settlement of the vast reaches of the solar system. Away from the prying eyes of Earth, space-going transnationals develop technologies that governments fear to investigate but cannot ignore, while bizarre posthuman cultures bloom like exotic flowers. It is a time of wealth and adventure, of transformation and terror. It is the age of
Transhuman Space.
The Earth of the 22nd century is not a post nuclear world, or one that was devastated by pollution. The mass of humanity shares in the fruits of progress, while technological advances have neither choked in regulations nor devoured their creators. Resources are not running out, and fewer people spend their lives suffering the privations of sickness or hunger than in the 20th century. Still, the world of 2108 is no utopia. Far too many of Earth's species became extinct and global warming has begun. Access to space has opened up new resources and opportunities, but created conflicts over who will use them and for what. Wearable or implanted computers, augmented reality, virtual telepresence, and artificial intelligence have given everyone their own set of personal aids and banished concepts such as "office" and "school". Meanwhile, privacy is very difficult on a crowded Earth where every glance from a passer-by means being scanned by digital video and profiled by inquisitive data-mining software. Then, while in the richest parts of the world people can afford longevity and genetic enhancements, in the less fortunate regions computer implants and infomorphs monitor and control the citizens.
Humanity: In 2001, cloning a human was a scandal, sex change operations were still controversial, and for many people the idea of prenatal genetic engineering to prevent disease in children was a blasphemy. One century later, hundreds of modified human germlines and dozens of parahuman species exist. There are engineered beasts with the knowledge of good and evil, not to mention voices and opposable thumbs. One may clone a dead spouse, grow a dog that talks, or arrange for his child to be born with a strong tendency toward beauty, mental stability, and mathematical aptitude. Then, there are offworld "black clinics" where one could have build a custom bioroid sex-toy, or give birth to a baby dragon. On Earth, the tide of public opinion about the more extreme genetic engineering ebbs and flows between revulsion, indignation, fascination, and tolerance.
Technological Level: Robotic and computer technology have reached high levels of development. Droids and robots of all sorts are equipped with AI
Artificial Intelligence and can often perform as well as humans. The latter live in
Augmented Reality, where computers and networks continually provide individuals with almost any requested information (unless it is restricted info), wherever they may be, except far away in space. It often takes the form of a virtual overlay of data display and digital mapping on either glasses or lenses, and sometimes directly reaches to brain through the use of implanted chips. Nanotechnology is also everywhere, with swarms of microscopic robots performing various functions, are overseen by pinhead-sized microcomputers running simple programs modeled on insect behavior patterns. Space travel is also well developed. Spaceships use fusion drives (using helium-3 extracted from Luna or gas-mined on Saturn), and can reach Mars in a matter of days/weeks or Jupiter in a matter of weeks/months. What doesn't exist yet, and is not seen to be developed in the near future, is Faster Than Light travel and artificial gravity / anti-gravity.
Earth's Nations: The political map of 2108 is not dissimilar to that of 2001. The nation-state remains the basic political unit, and there is no world government. Most governments are representative democracies, though sometimes in name only. Five major nations / regional alliances dominate Earth: China, USA, Europe, the Pacific Rim Alliance, and the Transpacific Socialist Alliance. China is in fact the most powerful single nation-state on the planet. It has the world's largest economy, one of the largest populations (1.48 billion), and a mature fourth wave technology (i.e.: Tech level 6) that boasts some of the world's finest genetic engineers. China possesses a large colony on Mars and smaller colonies elsewhere in the system. USA and Europe come second, but are wealthy fifth wave technology societies (i.e.: Tech level 7).
Colonization of Space: Humanity has begun the colonization of the Solar System. First, there are 400 manned space stations of all sizes orbiting Earth, the greatest of which is China's Taiko Station spaceport (picture above), in high Earth orbit. It has a transient population of 30,000 and is a first stop for many would-be Mars travelers. Then, there are bases on Mercury, Venus, Luna (Earth's moon), Jupiter's and Saturn's moons, as well as on several asteroids of the Main Belt. Mars is being terraformed, having now a denser atmosphere, water, plus a specific biosphere engineered to help further terraform the planet. Mars has a population of 2.5 millions of people. The largest political entity is China's Mars Province, universally known by its nickname "Rust china." The second largest colony is the United States' Martian Commonwealth, with a status similar to that of Puerto Rico at the end of the 20th century. The two are longtime rivals, with some tensions. Some Americans are jealous of China's superior position on Mars; some Chinese fear the United States plot to weaken Rust China. Each side has sizable military garrisons, and espionage is common. Then, other smaller colonies dot Mars.
Aliens: In 2108, Humanity still has to make first contact with extra-terrestrial intelligent species. Despite rumors and urban legends, no aliens have been encountered yet.
