[QUOTE="Thomas Bowman, post: 7417497, member: 6925649"] The setting date for Earth is 2491 AD the same as the first season of Buck Rogers in the 25th century. A few tech items are not available, no jump drives and no artificial gravity, and their are no reactionless thrusters. The bulk of the "fuel" carried by starships is reaction mass, the space that is normally allotted to jump fuel, but since we don't have a jump drive, there is no need for reactionless thrusters either, this keeps the cargo area for standard starships about the same, there is a separate fuel tank for the power plant. The power plant provides the energy for the maneuver drive. Since there is no artificial gravity except for the spin kind, then a lot of space colonies look like O'Neill cylinders. Typically these cylinders rotate inside hollow cavities within asteroids for radiation protection. All the standard races are available in this setting, they started out less technologically advanced than the humans, but the wormholes connect up and down the timeline as well as to different places, in one world the years is 11,800 AD, that would be the planet Forsetti which orbits Barnard's star, about 3.8 light years from that is a ringworld in the Sol System, there is no wormhole leading to the Sol System in that time, so people wishing to go their will need a slower than light starship and a lot of patience, or low berths to conserve on life support resources to get there, this I leave up to the GM, if he wants to include this ringworld in his campaign, he could make a suitable starship available to the PCs for getting there, and if not, then the PCs can't get there and the ringworld is not a campaign consideration. All of the wormholes were made by ancient aliens called "the Others" this is a technology beyond the sophonts of today so no more wormholes are in prospect. Antimatter starships are an expensive option for small starships, most of the price goes into manufacturing the antimatter, the containment issues are insignificant compared to the price of the fuel, the other option is a black hole starship, black holes are used to power military starships, they are analogous to the nuclear reactors powering the aircraft carriers of the US Navy, their big advantage is it allows a starship to accelerate continuously for longer than a fusion powered ship, because of the physics of small black holes only large billion credit starships are large enough to channel the decaying black hole's power into thrust. A military expedition to investigate the ringworld seems likely, but that would also mean making the capital warship unavailable for military missions for the number of years it would take to get to the ringworld, and since the top speed is 50% of the speed of light, a round trip is about 8 to 9 years.
