− | The | + | The RktkT Complicated Star System Generator is a detailed, but not ''too'' detailed, random star system and world generation system for Mongoose Traveller. It attempts to walk that fine line between realistic (as based on current astronomical and planetological research) and easy to use. Drawn from a number of sources, including the core rules, ''GURPS Space'' (for 4th edition), ''GURPS Traveller: First In'', various idea seeds on the [http://traveller.wikia.com/wiki/Traveller_Mailing_List Traveller Mailing List] and [http://www.travellerrpg.com/CotI/Discuss/ Citizens of the Imperium fora], and the [http://arcbuilder.home.bresnan.net/PCLMaster.html Arc Builder Planetary Classification List]. |
This is a "bottom up" system, where you start with the primary star and work through all the planetary orbits. However, a lot of the process has been greatly simplified and fudged, mainly so you don't have to go crazy calculating the molecular weight of the atmosphere and the effects of axial tilt, but also to make it easier to update the system when new scientific discoveries make it outdated. The end results are all in the conventional UPP format, with the addition of a single new rating, '''Biosphere''', to describe the complexity of life on the world. | This is a "bottom up" system, where you start with the primary star and work through all the planetary orbits.

I've made the assumption that minor bodies aren't worth mentioning. Assume all systems have a Kuiper belt and Oort cloud, that most Jovians will have their Trojans and Greeks, and that pretty much any planet at all has a number of minor satellites, meteor clouds, etc. Space is big. | I've made the assumption that minor bodies aren't worth mentioning.

− | – Shadowjack | + | Playtesting Notes (Last updated 6 June 2008: The tables seem to turn out rather small planetary systems, especially for the ubiquitous red dwarfs, but I'm not sure that's a bug; if anything, it makes it easier to cope. And considering that we still don't know how common planets ''really'' are in the universe; under these rules, the Sol system is neither rare nor typical, which works for me. If you want more planets, try applying DM +1 to the three orbit rolls. Microscopic life is fairly common and macroscopic life less so, which seems a reasonable assumption for Traveller, and there look to be plenty of quiet lifeless worlds suitable for terraforming. |

− | + | If a world doesn't have a colony, it might have an outpost. Roll 1d6, DM -1 in a culture's home system. If you roll less than or equal to (max. Jump rating), then an outpost has been placed there. | |

− | + | Each colony with Size 1-B, Atmos 1-D, and Pop. 1+ may attempt terraforming. Roll 1d6 for each century of habitation. For each die that comes up ''less'' than (max. Jump rating), you receive 1d3 points, which you may add to or subtract from the world's Atmosphere, Hydrosphere, or Biosphere codes, in order to make it more desirable. | |
+ | :If you want to introduce Earthly bioforms to a world with alternative biochemistry, you have to exterminate the existing life by reducing the Biosphere to 2 or less. You may then add the usual 1d6+5 Biosphere, for the new life forms. | ||
