Setting
[The setting for the game is fairly soft sci-fi, so try to bear that in mind as I try to handwave science away.]
Government
The Sol Republic has been the ruling establishment of Humanity for over six centuries, tracing its origins directly back to the Earth Unification Treaty in 2031, the Sol Republic is a constitutional democracy characterized by free markets and a strong focus on quaternary industry. The economic and social policy favors capitalism and personal liberties, with the Parliament having direct control over international policy and the military. The Sol Republic believes in personal liberty in all things, and as such attempts to stay out of the lives of its people as much as possible, therefore it does not provide many of the services that other nations do, [police, healthcare, transportation etc.], and as such taxes them appropriately.
Spacefaring Technology:
Spacefaring technology, being a new and integral field of engineering development has obviously seen the most impressive progress in the last few centuries. Faster-than-light travel is possible, practical and free of time-altering effects thanks to developments during the early expansionist period, with ships able to move at anywhere from one to four light-years per hour, depending on the engines and the mass of the ship. Hyperspace engines are massive and highly energy-inefficient, and therefore are not viable on small ships, with interstellar travel for the masses done by huge transports, akin to modern ferries. High-impulse engines with inertial sinks make piloting craft easy for the layman, and high-speed travel within systems is safe and convenient. Spacefaring vessels have been becoming both bigger and smaller, with private corvettes being no bigger than a yacht, and giant superfreighters dwarfing even military battleships for interplanetary trade. Interplanetary public transportation is easily accessible, and space elevators make entering and leaving the atmosphere easy. Humans are no longer constrained by suits when in zero gravity, having adapted with the help of medical science to be very well-suited to weightlessness. Artificial gravity without the use of linear acceleration or centrifugal force has not been developed, and changing effective gravity is something experienced spacers get used to. With the discovery of non-orientable wormholes, antimatter is easy to come by, and fuels most of the power needs of Humanity.
Medical: Medical technology is second only to space travel in its progress in the last centuries. Old age has become very rare, with the natural cap on human life expectancy well over 200 years, with most people living healthy and youthful until dying by some external means. Diseases are eliminated every day, with the bevy of vaccinations given to newborns increasing in scope and potency every year. The last true pandemic was decades ago, though medical science is still wary of the constant evolution of undiscovered diseases on distant planets. Trauma surgery has become incredibly sophisticated, with tanks of cloned organs at the ready to save lives, and clone replacements for lost body parts at the ready. Medical science has been fighting an uphill struggle of trying to create new clone body parts that are significantly better than the original without user difficulties or full-on body rejection, but progress is being made. Many religious people see this practice as against god’s design, and as such have been fighting the advances tooth and nail. Populations of settlements are always fixed by governments: seeing as death is much much slower now, and humans have not become any less procreative, certificates for childbirth are in great demand, and are a major source of government revenue.
Communications:
Instantaneous communication has existed for the last century, with it being perfected recently. This dramatic upgrade from lightspeed communication has made humanity even more interconnected than it was when it only inhabited Earth. Almost every human in Settled Space is connected on the multi-net, a dramatic, expanded internet, and the Net permeates every part of everyday life. Holographic technology has been perfected, and has revolutionised entertainment, and virtual reality is on the return, though still under the same stigma and scrutiny that all invasive, mind-altering technology is after the AI War.
Entertainment:Holographic technology has enhanced the way people view entertainment media, but the real advances are developing in the transmission of data directly into brains via Feelies, specially formulated media that places you directly in the situations. Feelies, though being an expesive and experimental new technology, are predicted to overtake all other forms of entertainment in the coming decades. The internet is even more important than it is, and has appropriated all other means of entertainment distribution.
