Notes (2015)[edit]

I have moved the summaries to Trade classification/summaries, to better reflect what the official nature of the text should be.

Thank you, Tjoneslo. I'll get used to the idea of how to do things here eventually. Spent a good portion of yesterday fixing "World" and "WorldS" problems. Thank you for teaching me how to correct those issues.

UWP Format for Trade Classifications (2007)[edit]

I've reaaranged the TC and Remarks page a bit, so that it flows in the same way as you'd find them in a UWP. I've also included links to LBB6 and MT:RM, although these may need to be altered so they point to the right page - I'll do this myself if I have time to find (or create) the required pages.

New MGT Trade Classifications (2008)[edit]

MGT (Mongoose) has a few new Trade Classifications, and some changes to the old ones as compared to MegaTraveller.

  • Ga Garden World, did not exist in MT.
  • Ht High-Tech, did not exist in MT.
  • In Atmosphere 3 not considered Industrial in MGT, it was in MT.
This seems to make an assumption that an Industrial world would taint the atmosphere.
  • Lo Worlds with 0 Pop not Considered Low Pop in MGT (1-3 MGT, <3 MT)
This may be because a world with nobody on it is zero pop? Not sure why.
  • Lt Low-Tech, did not exist in MT.
  • Ni <6 in MT, MGT is 4-6.
Not certain on this one, assuming a low enough population has to have some level of industry to sustain themselves, usually from off world?
  • Ri MT Also requires Government 4-9
MGT assumes people can be rich under any government type.

MGT vs. MT Trade Classifications (2009)[edit]

Most tools use the old MT format rather than the newer MGT formats. In the Spreadsheets I'm working on for processing sector data, I'm going to include an option to toggle between formats - but I thought it might need to be noted here about the differences. --Lotherius 03:12, December 14, 2009 (UTC)

Remarks and trade classifications indicate obvious or important characteristics for the main world in the system. They serve to show the potential for a world based on its capacity as a source of trade goods, a market for trade goods, or both.

Base codes show the presence of military bases in a system; special codes deal with the presence of more than one type of base within the same system in order to maintain a single base code letter per system.

If no bases are present in the system, the field may be empty, a blank (space) or - (dash).

Base codes have changed significantly between different editions of Traveller. Sector data collections must indicate which set of codes are in use. Sector data collections may also define custom meanings for base codes.





C Corsair Base. Vargr. D Naval Depot. Any. E Embassy. Hiver. K Naval Base. Any. M Military Base. Any. N Naval Base. Imperial. R Clan Base. Aslan. S Scout Base. Imperial. T Tlaukhu Base. Aslan. V Exploration Base. Any. W Way Station. Any. X Relay Station. Zhodani.

Multiple codes may be used if multiple bases are present. For example, NS indicates that the system contains both an Imperial Naval Base and an Imperial Scout Base. Base codes should appear in alphabetical order, i.e. MN rather than NM.
