I’ve been comparing the subsector generation of Mongoose Traveller (MGT) and Classic Traveller (CT) in the incarnation of The Traveller Book.
Here’s what I noticed:
The distribution of starports is different. Note how Classic Traveller has only a bit less D and a lot more A starports.
Bases are different: Mongoose Traveller has Research, Traveller Association, Imperial Consulate and Pirate bases; Classic Traveller only has Naval and Scout bases.
Temperature is different: Classic Traveller does not have it. Then again, I was always confused by the fact that it doesn’t show up in the Mongoose Traveller Universal World Profile (UWP).
Hydro is different: Mongoose Traveller has a modifier for temperature; Classic Traveller does not. That explains why temperature doesn’t appear in the UWP: it wasn’t used by CT.
Population is the same and limited to a maximum of A when rolling, but the table in Mongoose Traveller also describes B and C. Perhaps this is a nod to Coruscant, the world city in Star Wars?
Government is the same and produces a range of -4 to 15 (F) when rolling. Both only describe governments 0 to 13 (D), however. How strange.
E Religious Autocracy. Government by a single religious leader having absolute power over the citizenry
F Totalitarian Oligarchy. Government by an all-powerful minority which maintains absolute control through widespread coercion and oppression
– MegaTraveller Referee’s Manual, apparently
Law is similar in that the dice throw produces a range of -5 to 15 when rolling, assuming we limit Government to 0 to 10 (A). Mongoose Traveller only describes Law 0 to 9; Classic Traveller describes Law 0 to 10 (A).
Tech is different. Mongoose Traveller has modifiers in the table for populations B and C, but you can’t get more than A so this is a bit strange. Mongoose Traveller increases Tech by +1 if you have Hydro 0. Mongoose Traveller increases Tech by +2 if you have Government 7 (Balkanisation), which is weird. Mongoose Traveller decreases Tech by -2 for Government 12 and 13 (charismatic oligarchy and religious dictatorship); Classic Traveller only does this for Government 12. No penalties for religious dictators, I guess.
Trade is also different, mainly in that some codes are missing in Classic Traveller: Barren (Ba), Fluid Oceans (Fl), Garden (Ga), High Population (Hi), High Technology (Ht), Low Population (Lo), Low Technology (Lt).
Travel Codes (Red, Amber) are not codified in Classic Traveller; Mongoose Traveller suggests when to use the Amber code.
Routes appear only in Mongoose Traveller.
The pirate bases, the travel codes, and the routes sure make the maps generated for Mongoose Traveller more interesting to look at.
Here is an example subsector generated. Notice the limited bases created.

I’ve left the Mongoose Traveller suggestions for routes in place and this is what we get:
On G+, I got linked to TRAVELLER: Out of the Box – Interlude: Two Points Where I Prefer the 1977 Edition Over the 1981 Edition talking about the old 1977 trade routes. When I tried it, not bad! (Also note this forum thread, Default CT 1977 and CT 1981, comparing the 1977 and 1981 editions; log in to see more than just the first message of the thread.)
(Classic Traveller map, with minimal spanning tree)
I decided to drop the optimising I had been doing, to get a feel for the “raw” data. This also required some rewriting and this always messes with the random number generator. That’s why this map cannot be easily compared to the one above.
I did some rewriting and added the minimal spanning tree algorithm again. It looks less busy, the clusters are still clusters. But there are some drawbacks. Take a look at the top right corner: 0802 and 0703 are connected (distance 1, shorter connections go first), 0701 and 0703 are connected (distance 2), and thus 0701 and 0802 cannot be connected because that would introduce a loop.

I think for the time being I’ll remove the minimal spanning tree optimisation again.
