Following the split that took place earlier, I am posting Content articles over at The Etzina Passage, but alternative Rules articles (and reviews) here on Gaming with Chuck. This is an alternative (or house) rules article. It has to do with a modification to the Mongoose method of rolling up system contents (other than the main world). It has been inspired by my investigation of the new T5 from Marc Miller.
As a modification to the system contents developed earlier, here, this is an alternative method to develop the nature of the worlds within the different orbitals, inspired by the work in T-5 (pages 426-443).
Once the various orbitals are filled, follow the rest of the procedure shown earlier, for determining the location of left over planetoid belts and gas giants, and then for developing the location of significant bases.
Inner Zone Occupied Orbital
2d6 - Check against following
Double 1 - Gas Giant (if exists)
Double 6 - Companion Star, place in last orbit of system, ignore (reroll) future Double 6
Otherwise, look at lowest of the two dice.
| dice | Result |
|---|---|
| 1,2 | Roll on Inner Zone world table |
| 3 | Planetoid belt, if possible, or Size 1 world (Worldlet) otherwise |
| 4,5 | Roll on Inner Zone world table |
| 6 | Planetoid belt, if possible, or Size 1 world (Worldlet) otherwise |

Chance for satellite?
- Gas Giant - 1d-1 (significant satellites)
- If 0 is rolled exactly, there is a ring (only)
Otherwise, then 1d6 (3+) chance for ring - Other Inner Zone worlds - 1d-5
- If 0 is rolled exactly, there is a ring.

Habitable Zone Occupied Orbital
2d6 - Check against following
Double 1-5 - Gas Giant (if exists)
Double 6 - Companion Star, place in last orbit of system, ignore (reroll) future Double 6
Otherwise, look at lowest of the two dice.

Otherwise, then 1d6 (3+) chance for ring - Other Habitable Zone worlds - 1d-4

Outer Zone Occupied Orbital
2d6 - Check against following
Double 1-5 - Gas Giant (if exists)
Double 6 - Companion Star, place in last orbit of system, ignore (reroll) future Double 6
If total of 2d6 is greater than orbital, then Gas Giant (if exists)
Otherwise, look at highest of the two dice.
| dice | Result |
|---|---|
| 1,2 | Roll on Outer Zone world table |

World Types
For all of these different world types, if it is not a Main world, then it will only have a Space Port, rather than a Star Port, otherwise generate as if a Main World. Maximum Population is Main World POP -1.- Wordlet
- Size = 1d6-3. Otherwise, generate normal sequence.
- Secondary World
- Population -4; Hydrographics -4. Otherwise generate normal sequence.
- Ice World
- Population -6. Otherwise generate normal sequence.
- Storm World
- Size=2d6; Near constant high winds and storms. Atmosophere +4; Hydrographics -4; Population -6. Otherwise generate normal sequence.
- Rad World
- Size=2d6. Extremely high radiation. POP=0, GOV=0, LL=0. Otherwise generate normal sequence.
- Big World
- Size=2d6+7. Otherwise generate normal sequence.
- Inferno
- Spaceport = Y (no facility). Size=2d6. Atmosphere=B (Corrosive). Hydrographics=0. POP=0, GOV=0, LL=0.
- Habitable World
- This is a world that could be a candidate for a Main World.
Spaceports
Non Mainworld Spaceports are generated like this:Roll POP - 1d6. Results are:
2- Spaceport F (Good facility, minor repairs, unrefined fuel) - Downport, good quality terminal.
3 Spaceport G (Poor facility, superficial repairs, unrefined fuel) - Downport, basic terminal.
4,5 Spaceport H (Basic facility, no repairs, no fuel) - Landing slab and a beacon
6+ Spaceport Y - same as Starport X
If there is an Orbital Facility, then it is automatically Spaceport G or higher. If there is a Surface Facility, then it is automatically Spaceport H or higher.
Interesting. How do you feel it will change the nature of the systems? Will they be richer, more varied, or will it have a different distribution?
ReplyDeleteMaybe it'll just be more fun or feel a little more 'hard SF'?
I still use the Megatraveller system as embedded in the Heaven and Earth software package.
Hi Tom - I think, that if this were applied on a subsector wide scale, or broader, that it would introduce a (potential) great deal of depth to the number of interesting locations that a group of adventurers could visit in a reasonable amount of time. With a multiple number of interesting things to do and see in a single star system (which I suppose, were always there, but not detailed in the simpler subsector listings), it means less required time in jump space to visit new places.
