O.k. now that have you gathered here I guess I should tell about the universe as of this moment.
Earth is not a corporate dystopia, governments fought back.
O.k. so before we go through the rest of Earth I will tell you about the solar system.
Mercury is a planet with a few corporate bases, mainly chosen for abundant energy, or when you want to hide something.
Not much is going on with venus, it is still too much of a hell-hole to be useful.
Mars, is undergoing limited terraforming with Genetically modified plants for food, more corporate bases.
In the asteroid belt are them miners, a growing industrial force, considered to be the largest nation of space, in size, and population after earth.
Then there is Jupiter a massive corporate U.N. running the place.
Saturn is the last heavily colonized place, and it is where the most wars take place, quite anarchist.
Beyond them ends main civilization, the outer areas are controlled by a few self sufficient prospector groups, though they are by no means powerful.
Combat, takes place in gravity wells, almost exclusively, time delays in deep space make it to much of a pain.
Ships: bear bones constructs, occasionally with centrifuges, main engines are either Ion, in the local transport areas, like the belts, VASMIR or Fission rocketry, like VASMIR, just more powerful, for long range, some groups have limited suspended animation techniques.
Energy is entirely thorium, and in some places Uranium at this point, so of course this is hotbed for competition.
Computers are beginning to use molecular transistors.
Now for earth the most advanced place, spaceplanes facilitate the limited expansion into the solar system, there are floating launch platforms, but sending things from a gravity well is still expensive, no matter where you are, but many groups are rushing towards the holy grail, a space elevator.
Fusion power needs some finishing touches before it becomes practical, but then a new era of energy, and transport will be possible.
Tech that that are waiting for love:
Fusion, nanorobotics, optical or quantum computers, megascale engineering.
