Variant Main World Generation System for Traveller -------------------------------------------------- 1. World Size. Roll 2d6-2. 2. Atmosphere. Roll 2d6-7+Size. if size=0, atmos=0. confine range to 0-F. 3. Hydrographics. Roll 2d6-7+Size. if atmos is 1 or less, DM -4 if size is 1 or less, hydro=0 if atmosphere is A-C, DM -4 if atmosphere is E, DM -2 confine range to 0-A 4. Indigenous Life. Roll d12-1 twice, take lower of two rolls if atmos is 1 or less, then life = 0 if atmos is A-C, DM -6 if hydro = 0, DM -4 if life is A-B, 50% chance of DM +2 confine range 0-D if life is D, conduct eco-collapse: atmos=C hydro, DM -4 confine hydro 0+ Life Stat Explained ------------------- 0: Sterile: No indigenous life. Atmosphere is not breathable without substantial eco-engineering. 1: Proto-cellular: Indigenous life consisted of amino acids and/or various primitive replicators. These may have been wiped out by transplanted organisms. 2: Single-cellular: Transplants would have taken over. 3: Multi-cellular: Transplants would have taken over. 4: Complex microscopic: Lots of colorful ooze. Transplants would have taken over for the most part, however, there might be some indigenous bacteria still competing. 5: Macroscopic: Mainly small indigenous sea-life which would be competing along side whatever transplants are present. 6: Primitive ecosystem: Oceans are teaming with indigenous organisms, but land-based life is just carving out its niche. Transplants may have halted the advance of indigenous life, assuming the two are bio-compatible. 7: Teaming ecosystem: Water/Land/Air-based herbivores and predators. Transplants would have a hard time competing in such an advanced ecosystem. Bio-compatibility would be an important issue. 8: Proto-sentient: Tool-fabrication, mastery of fire. 9: Sentient: Agriculture, language, symbology. A: Non-spacefaring: Planet may be a biological protectorate (ala the Prime Directive). B: Early Spacefaring: Indigenous race may have been given technology or may even have been genetically uplifted. C: Cataclysm: Result of either war, plague, or minor environmental mismanagement. Survivors are in a state of slow recovery. D: Green Hell: Result of major environmental mismanagement. World is transformed into a greenhouse. 5. Resource Level. Roll 2d6-7+Size confine range 0-F Resource Stat Explained ----------------------- 0: Barren 1-4: Poor: Basic chemical diversity necessary to support indigenous life. Otherwise, no claim to fame. 5-8: Moderate: Moderate resource base capable of being exploited for export. 9-C: Rich: Rich resource base, one of which could command subsector-wide influence. D+ : Extreme: Very rich resource base, one of which could command sector-wide influence. 6. Population. Roll 2d6-2. if size is 2 or less, DM -1 if atmosphere is 3 or less, DM -3 if atmosphere is A, DM -2 if atmosphere is B, DM -3 if atmosphere is C, DM -4 if atmosphere if greater than C, DM -2 if atmosphere is 6, DM +3 if atmosphere is 5 or 8, DM +1 if hydro=0 and atmos>3, DM -2 if life is 0, DM -2 if life is 7+, DM +2 if res is 0, DM -3 if res is 1-4, DM -1 if res is 5-8, DM +1 if res is 9-C, DM +2 if res is D+, DM +3 confine range to 0-A 6b. Population Multiplier. Roll d9. if pop is 0, 5 in 6 chance that popmult = 0 7. Starport. Roll 2d6 (use whichever table suits the locality but remember that high rolls result in a lower quality starport). if pop=0, starport=X if pop=1, DM +2 if pop=2, DM +1 if pop is 6-9, DM -1 if pop is A, DM -2 confine range to A-X 8. Government. Roll 2d6-7+population. if pop=0 and popmult=0 then gov=0 confine range to 0-F 9. Law Level. Roll 2d6-7+government. if gov=0 then law=0 confine range to 0-20 10. Tech Level. Roll d6. Modify as per the standard chart for starport, size, hydro, and pop. Modify as per standard chart for atmosphere except for D-E range. Modify as per law as follows: if is law B-D, DM -1 if is law F+, DM -2 Modify as per government as follows: if gov = 1 or 5, DM +1 if gov = 13 or 14, DM -2 if gov = 6 or 15, DM -1 if pop=0 & popmult=0 then tech=0 confine lower bound of range to 0 11. Technical Depopulation. if hydro is 0 or A and pop is at least 6, then tech must at least be 4. if atmos is 4, 7 or 9, then tech must at least be 5. if atmos is 3 or less or A-C, then tech must at least be 7. if atmos is D or F and hydro is A, then tech must at least be 7. if tech is less than minimum requred tech then: pop=0, popmult=0, gov=0, law=0, tech=0, starport=X 12. Trade Classifications As per MegaTraveller rules except as follows: Deleted: Rich, Poor, and Industrial, Nonindustrial, Non-agro Modified: Agricultural (may include hydro 9+) Fluid (no size restriction, atmos A-C, hydro 1+) 13. Main Export Commodity. if res = 5+ & tech = 1+ & pop=5+ then try to assign an export (try as many times as there are resource points, choosing the best outcome based on tech level) if AG, export = d5 otherwise, export = d29+4 if no export is selected, then export=0 Export Stat Explained --------------------- Roll Tech Etc 0 None 0 - 01 1 Textiles 5 A 02 2 Wood Products 4 A 03 3 Livestock 1 A 04 4 Agro-Consumables 4 A 05 5 Pharmaceuticals 9 - 06 6 Petrochemicals 6 L 07 7 Biologicals 1 L 08 A Antimatter H - 09 B Bio-engineering D - 10 C Computers D - 11 D Industrial Crystals 5 - 12 E Electronics C - 13 F Farm Machinery 5 - 14 G Gemstones 1 - 15 H Heavy Metals 5 - 16 I Industrial Machinery 5 - 17 J Synthetic Fabric 8 - 18 K Synthetic Foods 8 - 19 L Industrial Chemicals 7 - 20 M Rare Minerals 5 - 21 N Weaponry/Armor A - 22 O Radioactives 6 - 23 P Polymers 9 - 24 Q Cybernetics C - 25 R Robots D - 26 S Starships B - 27 T Tools 5 - 28 U Underwater Equipment 7 - 29 V Vehicles/Gravitics 8 - 30 W Banking/Insurance D - 31 X Entertainment D - 32 Y Art/Publishing/News D - 33 Z Information/Research D - Tech=X: X is the minimum tech level Etc=A: World must be Agricultural Etc=L: Life must = 7+ 14.
