I did a "Twilight2000 in space" campaign where the PCs participated in a small war over the resources of a newly discovered system with French Mercs. We used the V2.2 rules conversion I mentioned above.

I went with this being a "bridge" to the Traveller universe so I also included the Varger, Aslan, and Dryonne(?) from Traveller. I also used the Jump Drive of Traveller modified to 2300 specs.

I don't have the formula handy, but Jump times were no longer just a week.
The time in hyperspace was calculated by inputing the [DISTANCE JUMPED (in light years) x 1/100th SHIP DISPLACEMENT (in tons)] divided by [MEGAWATTS (put into the Jump Drive) x DRIVE EFFICIENCY] = DAYS IN HYPERSPACE. The big issue was establishing a TRAM Line (Translight Routing & Astrogational Mapping Line). The Astrogation Skill was used to plot a Jump and there were various established JUMP POINTS that could be used based on the risk the players were willing to accept.

- A MAJOR TRAM Line Route has been jumped at least 1000 times at all times of the celestial year and is an EASY test of Astrogation. This is a basic low-risk Jump.

- A PRIMARY TRAM Line Route has been jumped at least 100 times at all times of the celestial year and is a ROUTINE test of Astrogation skill.

- A SECONDARY TRAM Line Route has been been jumped at least 10 times at all times of the celestial year but more likely jumped much more often at SPECIFIC times of the year (such as during harvest times) so the Astrometric data is not as complete for this TRAM Line. The Astrogation test is an AVERAGE one.

- A TERTIARY TRAM Line Route has been jumped a dozen times or less. The data is certainly not complete for the entire celestial cycle. The Astrogation test for this jump is a DIFFICULT one.

- A PLOTTED TRAM Line is a Route that has been successfully jumped...ONCE. The Astrogation test for this jump is a FORMIDIBLE one.

- A CUSTOM TRAM Line is a Route that your PCs plot for themselves. It has never even EXISTED until your crew plotted it. The Astrogation test for this Jump is an IMPOSSIBLE task.


Maneuver Drives used Hydrogen Fuel PELLETS to accelerate and decelerate in G's like an Epstein Drive (even though the EXPANSE was still 20 YEARS away when we played).

The worlds were gritty and became a mashup of the Aliens universe mixed with Bladerunner and Space: Above & Beyond. It was well-liked.
