For My Timeships campaign, I decided to set it on a timeline where there is not otherwise any other FTL drive, the only problem is that the Time Drive does not arrive until Tech level 20. On my timeline that does not occur until 2766 AD, there is a lot of time to colonize the stars using slower than light drives. Below is an example of a Far Trader without the Jump Drive, the jump fuel tank remains and with a reactionless drive, the results can be pretty impressive:
Not this setting has everything the OTU has except no Jump Drive. Research on faster than light technology instead focused on the creation of tachyon particles using unstable wormholes, the tachyon particles kept on disappearing after a certain distance was crossed, so while the researchers were working on the mechanics on how to build a Time drive, colonization of nearby stars proceeded using the reactionless maneuver drive only. Low Berths were often used to save on life support and in storing multiple year's supply of food for the crew. This thread will concentrate on the economics of slower than light starships, and what that means. Of course the Solar System gets developed much more extensively, with terraforming projects going on with Mars and Venus, since interstellar travel is much more time consuming and expensive. A starship can make several interstellar trips in its operational lifetime, after each trip and expensive overhaul is required, a lot of the ship's parts will need to be replaced or upgraded.
