Preliminary thoughts on some Triplanetary variants
One of the problems in using Triplanetary in this way is that Cherryh's ships are way more powerful than anything fielded in Triplanetary, not only in raw combat power but also in terms of engine performance. As a result, it's simply inconceivable that the Norway, for example, would go careening off into space because of a gravity arrow, but Mallory might use the gravity of a planet to perform a maneuver otherwise outside Norway's performance envelope. Also, planets and such are important because they are obstacles to hide behind, and because they potentially can affect a ship's jump drive.
The solution in this case, I think, is to simply treat all the gravity arrows (except those around the star) as being optional. Presumably, uses of thrust sufficient to show up at the scale we are playing the game in are the "7Gs slammed into your seat" impulses, not routine maneuvering thrust that we see all the time.
This rule does beg some interesting questions, e.g., can ships now break orbit without expending thrust? How are the hollow gravity arrows handled? How are unpiloted objects (mines and torpedoes) handled? I haven't thought through all these ramifications yet -- but check this space for further developments.
Here are some preliminary thoughts on combining the two:
- The single combat value used in Triplanetary split
into an offensive and defensive rating. There is a chart
in the Albedo Ship Sourcebook which gives
this value on a per-weapon system basis.
- In addition, there should be some defensive value
based on the size of the hull. Large ships are less
vulnerable than small ships.
- Point defenses are used as DRM, as in
Albedo combat rules. They should probably
only be effective to a point, however, as we don't want
ship to become invulnerable. Excess capability above the
point provides redundancy in event of damage.
- A more detailed combat table could be used. Ships in the Albedo universe usually take some damage -- occasionally even very severe damage -- yet continue to retain some functionality. Perhaps Triplanetary's d6 table should be replaced with a d10, with some of the results being critical hits (which would use the damage tables found in the Albedo RPG).
These are only some preliminary thoughts -- please feel free to comment on them, and check back for further developments.
