Traveller

2017-07-14 Name Generator

I was wondering how to give each random Traveller sector or subsector generated its own “touch” and I remembered the notes on generating names for the Twitter bot @unchartedatlas.

My generator uses a digraph based random generator, an idea going to back to the original Elite. What I’m doing now is randomly generating the list of digraphs to use for each sector or subsector, thus making the generated names more or less similar to each other. If you want to experiment with the name generator on its own, I installed it as a separate web application. Perhaps it can be useful to generate random names in fantasy languages. The Help page shows how to start with lists of digraphs based on the Japanese and Hawaiian language.

Who knows, it might be useful for your orc needs...

I then added code to parse multiple characters as one – moving from code digraphs to linguistic digraphs like “ch” or “th”. These can then be counted as a single consonant.

The Traveller generator now picks a random subset of English consonants and vowels, including some digraphs, as I said, and I think it works rather well.

2017-07-11 Traveller vs. Traveller

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.

2d6MGTCT
2XA
3EA
4EA
5DB
6DB
7CC
8CC
9BD
10BE
11AE
12AX

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.

But reddit has the answer:

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:

Classic Subsector

(If you click the image, you’re going to see the Traveller Subsector Generator with a secret parameter for creating Classic Traveller maps.)

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.)

Classic Subsector

(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.

Classic Subsector

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.

Classic Subsector

(Classic Traveller map, with minimal spanning tree)

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

Comments on 2017-07-11 Traveller vs. Traveller

There should be a space lane between 0601 and 0701 by the 1977 rules (A-B J-1 is 1+ to have a space lane). Also 0504-0505 and 0508-0607, hmm and a bunch more...

– Frank Filz 2017-07-13 07:31 UTC


Indeed! A bug!

– Alex Schroeder 2017-07-13 09:25 UTC


New code produces:

1619343301-ct4

– Alex Schroeder 2017-07-13 09:35 UTC


Highlighting jump-1 routes:

1619343301-ct5

Not sure about the colour scheme. And the legend at the bottom needs fixing.

– Alex Schroeder 2017-07-13 10:59 UTC


Nice, I like the red to highlight the J-1. When I did my subsectors, I ended up not rolling for the J-3 and J-4 routes. I also didn’t bother with a J-2 route that was already connected by J-1 (for example 0604-0804 above, there’s already an implied J-2 route as 0604-0705-0804). Similarly you could remove the 0305-0604 J-3 route (unless there isn’t a J-2 between 0305-0505 and that blue line is actually JUST a J-4 route 0305-0705...).

– Frank Filz 2017-07-13 16:28 UTC


Hm... Isn’t that a bit like the minimum spanning tree optimisation? As Ian Borchardt said on G+:

One problem with your optimised paths is that you are assuming that space == time, which isn’t the case with Traveller jumps, because any jump takes two weeks, regardless of distance. [IIRC]

Which means it’s not cheaper (time wise) for a starship to call in at an intermediate port. So given a choice between A-B-A and A-A most people will still choose A-A by preference because it gets there in half the time. It has a greater efficiency.

I responded with the following:

As for trade route optimisation: one might say that the trade routes indicate the most popular trade routes and thus two jump-2 segments will be more popular than a single jump-4 segment because there will be more ships that can handle it, even if that makes the route take twice the time. Well, that was my argument when I realised that too many routes just made for an ugly map.

So basically the jump-2 route 0604-0804 says that ships can and will make this jump directly – unlike the jump 0604-0703, which is also a jump-2 but somehow the dice have decided that it’s not profitable enough to do. It’s up to the referee to explain the difference. At least, that’s Ian’s argument.

For myself, I’m still undecided. All I can say is that it looks busy and messy and I don’t like it too much.

As for distance, I guess from a player perspective, at the beginning of a typical campaign all we care about are jump-1 and jump-2 routes. Perhaps I should just use a third colour for jump-2 routes.

– Alex 2017-07-13 16:52 UTC


Support for sectors, click to zoom. Note how I used a third color for jump-2 routes.

Click to zoom!

– Alex 2017-07-13 18:03 UTC


D’oh. I just noticed that my generator never generated any gas giants. Fixed!

This also means that all the random seeds will now generate different maps. Nooooo!

– Alex 2017-07-13 18:33 UTC


As for picking a subsector capital, Ian Borchardt says:

Definitely an A class spaceport (and it will have an attached Imperial naval and scout base). It probably should be a Rich world (Atmosphere 6-8, Population 6-8), and I’d assign it a Government Type of 8. The TL should be amongst the highest in the subsector (and a minimum of 12).

And regarding trade routes, he says:

This is the approach I would take.

First generate the main routes.

(1) Connect all Starport A within Jump 2 of each other.
(2a) Connect all Starport B within Jump 2 of a Starport A.
(2b) Connect all Starport B within Jump 1 or each other.
(2c) Connect an unconnected Starport B to another Starport B within Jump 2.

If a connection in step 2 connects Starport A to the sector capital then upgrade it to a main route.

Next comes the feeder routes.

(3a) Connect Starport C to a single Starport A within 1 jump.
(3b) If not connected, connect Starport C to a single Starport B within Jump 1.
(3c) If not connected, connect Starport C to a single Starport A within Jump 2.
(3d) If not connected, connect Starport C to a single Starport A within Jump 2.
(4a) Connect Starport D to a single Starport A within 1 Jump. (optional)
(5) Class E starports are never connected by a trade route.

If in need of direction, assume the shortest path to the subsector capital.

This defines the regular services (for various definitions of regular). Everything else relies on tramp freighters.

[In your example map the small disconnected group of systems to coreward might have better trade connections to coreward than it does with the subsector it is technically a part of. Or it may be a different polity. And yes, I cheated with the rosette of class A and C starports to rimward, because of a fondness for benzene rings...]

– Alex Schroeder 2017-07-13 22:31 UTC


One thing I did to simplify my route maps is that if you have three worlds, One, Two, and Three, and there is a J-1 route from One to Two, and a J-1 route from Two to Three, I also assume the J-2 route from One to Three is also regularly travelled. I also in a few places, having rolled just the J-2 route, assumed that the J-1 routes were thus also regularly travelled (this makes a world that might otherwise have had less access have more, I’m not that bothered by that, and would rather have a simpler map).

2017-07-11 Tales to Astound

With my renewed interest in Traveller comes a new blog, Tales to Astound!

Some samples!

«And I type all this up to say–the game was written and designed to play this easy, fast, and loose play–and you can play this way too. No long, detailed introduction from the Referee about politics that the Player Characters can’t influence anyway. No thoughtfully pre-planned adventure the Player Characters are supposed to follow. No expectations of what the Players will do.» – An Improvised Classic Traveller Convention Game

«Why van Rijn, let alone anyone, would be hauling around whisky between the stars and assume to make a profit is insane, of course. But that’s exactly what the trade rules in Traveller model.» (Comes with some interesting quotes from books that are said to have inspired Marc Miller as he wrote Traveller in 1977 and 1981.) – TRAVELLER and “Hard Science Fiction” — I don’t think so…

«It really reinforces the nature of the Referee as impartial judge, the dice as oracles, and the rolls not as “skill rolls” but as impartial tools to determine outcomes. The point of the roll is not to see “How well the character did,” but to see what happened when the character did something, which in turn leads to the character having to do the next thing, based on the outcome of the roll.» – TRAVELLER: Out of the Box-An Approach to Refereeing and Throws in Original Traveller (Part I)

«It has long been noted that the Classic Traveller does not have a unified task resolution system. Instead it has an ad hoc system of Throws, with different Throws for different skills, and many of the rolls left without any sort of specific procedure or definition. For many, many people this is a problem. People want to know how the game works in a simple, consistent manner.» – TRAVELLER: Out of the Box–An Approach to Refereeing and Throws in Original Traveller (Part II)

«The dense layer of procedural generation of Worlds, Encounters (NPCs, Animals, Legal, Patron), Encounter Range, and NPC Reaction lets me generate content on the fly and help me come up with new ideas, locals, and situations I would never come up with on my own.» – My Favorite SF RPG…

2017-06-30 Traveller Subsector Generator

Yesterday I posted some Traveller links. Today I refactored my Traveller Subsector Generator and moved to a new web framework. I also merged my UWP Generator and my SVG Mapper for Traveller into a single web app, the Traveller Subsector Generator. I hope it’s pretty obvious how to use it, but I know that sometimes I get confused myself so here’s what it can do:

You start with an editable example UWP:

  • Generate Map gives you the SVG map
  • Communication and Trade Routes gives you a list (text)
  • Random Map gives you a random SVG map

If you’re looking at an SVG map and you got here via Random Map:

  • UWP in the bottom right gets you the read-only UWP that generated the map
  • if you do that you can click on Generate Map and get the same SVG map
  • this works because the random map has a unique id

If you’re looking at an SVG map and you got here via Generate Map:

  • since you might have edited the UWP, it doesn’t have a unique id
  • and thus you don’t get the UWP link

If you’re looking an a read-only UWP:

  • Random UWP generates a new, random, read-only UWP
  • Generate Map takes you to the SVG map, as I said
  • Edit Map takes you back to the edit screen for this UWP
  • this works because the read-only UWP has a unique id

OK, so the only weird thing is that sometimes there is no UWP link back from the map, right? Well, if you’re looking at https://campaignwiki.org/traveller/edit/344450615 and click on Generate Map then you can always use that id in the URL and type https://campaignwiki.org/traveller/map/344450615 into the address bar of your browser. And now the missing UWP link appears!

I don’t even know why I’m posting all this. I makes me realise that the user interface needs more tinkering and I’m tired. If you have an idea for how to make it more obvious, specially if you haven’t used it before and you’re confused, I’d like to hear about it. Perhaps we can improve the web app together.

Traveller Subsector Generator

Why is classic Traveller the simple generic system that drives adventure? My Favorite SF RPG… talks about all that.

The PCs can’t do everything, of course. The character generation tables offer a limited set of skills, and PCs will only have a few of those per PC. But this means that if the PCs don’t have the skill set available they will have to come up with adventure-driven schemes and shenanigans to keep going: steal the part they need to fix their ship because they don’t know how to fabricate it; get to the professor of ancient languages held against his will on the estate of the noble to translate the alien tablet they found; sneak into the government building using a clever ruse because this group doesn’t have someone with Computer skills; and so on.

Deciphering the Text Foundations of Traveller is a rabbit hole about the literary sources of Traveller.

The creators of CT wanted the anarchic, amoral, and violent adventure of fantasy role playing translated into a science fiction setting.

An excerpt by Paul Czege from a long comment on the article above on a thread by Martin Ralya on Google+:

Travellers in a country that isn’t open for tourism, ex-military guys, characters in Tales of the Quintana Roo, can’t resist someone saying, “Man, you have to see the Erradeca temple ruins! A group of us found a guy who can show us the way.” Ex-military guys are rootless, have time on their hands, a certain confidence and hunger for new experiences, and have skills most other folks don’t have. I think Marc Miller originally designed a game that’s truly about the kinds of characters who love travel and new experiences, like military folks he knew. This closely matches Andre-Driussi’s take. Screw the focus on owning a starship. These characters aren’t about being in space. They’re about experiences on planets. The original focus of the game is why you have stuff like the Traveller’s Aid Society and ship passages that no one ever does anything with. The characters don’t want to own ships. They just want to get from place to place. It’s called Traveller! I’ve thought a lot about why it got drifted to a tramp merchant thing in the first place. I think the answer may be that it’s not easy at all for players to get excited about seeing an alien ruins, or a once-in-a-hundred-years creature migration that has to exist entirely in their imaginations.

Here’s a Classic Traveller Character Generator by Paul Gorman.

I wrote a Traveller Subsector Generator. See the screenshot at the top of this page. Or you can use Text Mapper.

I think you could run a campaign just looking at concept ships all day.

Oh, and if you’d prefer a fantasy game instead, Paul Elliott has Mercator for you.

An Interview with Marc Miller.

Jeff Rients has you covered: Traveller: Where to Start. Basically, one of the old sets. These days, you can also use Mongoose Traveller. As far as I can tell, it’s main benefit is that it has a unified task resolution system. Just roll 2d6, add all the modifiers and get 8 or better. But Jeff says: «I think a single resolution system for all actions is not the right way to run Traveller. Detractors of the original rules like to say that Classic Traveller’s big flaw was lack of unified resolution mechanics. I consider that a feature, not a bug.» I guess it makes it more obvious that the referee sets the difficulty level of all rolls. That works for me.

Comments on 2017-06-30 Traveller Links

I think the post you quoted from Martin Ralya gets to what I’ve always felt was the core of the Traveller game.
Instead of characters who work to travel from interesting port to interesting port, in many cases a starship becomes the characters’ new home, which fails to capture the itinerant nature of the setting.
This is fine as far as it goes, and of course people should play the style of game they like, but I think the game is much more interesting when players look to their characters’ backgrounds as a way of dealing with ever-changing circumstances of all types, than as a straitjacket to lock characters into a specific campaign style, be that paramilitary or trading or empire-saving.
Frotz 2017-07-05 14:01 UTC


All I can say is that my Traveller campaign folded. I got charmed by Diaspora and half a year later we switched away from Traveller. Micro management of the wrong kind of things was part of the problem: no body cared about trade and payments, and yet we felt this is what the game is all about.

– Alex Schroeder 2017-07-05 14:28 UTC


I bought The Traveller Book (1982). According to Guide To Classic Traveller: «The Traveller Book consolidated the core rules (Books 1-2-3) into a single 8.5 x 11 book and added additional material on how-to-play the game. It also added the short adventures Shadows (from Double Adventure 1) and Exit Visa. 159 pages hardcover with dust jacket, or softcover.» As my campaign ran using Mongoose Traveller, I am interested in the differences.

Google has some forum threads for me to look at... but they make me tired. I’ll just browse the PDF, now.

2012-10-19 More about the Mashup

https://alexschroeder.ch/pics/8102076024_67c3d07001.jpg

Today I posted about my Planescape-Spelljammer-Traveller mashup on Google+ and I was asked to say more about it.

Basically the players got hold of a Spelljammer ship to sail the astral sea. It was one of the classic ships: a Mindflayer Nautilus class called the Black Strangler. Basically the astral sea is what Planescape has as the sea at the bottom of Celestia. When I read about the astral plane, the big wheel and all that, I was confused and I figured the players would be as well. Instead I opted for something alike Marion Zimmer Bradley’s travel to Avalon: get on a boat, travel for a bit, use some magic and you can be elsewhere. I think the astral sea is how D&D 4E does it as well?

Anyway, so we have a “sea” and “islands” on it – or basically worlds, systems. It already starts to sound like a bit of Traveller. Many of them will have gates linking them with larger worlds – fantastic worlds inspired by Planescape: hells, elemental planes, alternative prime material worlds. A bit like Philip José Farmer’s World of Tiers, perhaps?

One world, for example, is non-magical except for the gate that leads to the astral sea. So they built a fortress in the astral sea and discovered that magic works on the other side. Now they use it like a space station or star port to manufacture mundane stuff that requires magic to be built.

All these small worlds, astroids and stations get an UWP and I feed it to my Traveller Subsector Mapper to produce a nice map. Check out the astral sea map and click on the systems to go to the campaign wiki pages.

I think my greatest inspirations from the web where the One Page Dungeon submission The Forgotten Depths by the author of The Metal Earth and the session reports on Planet Algol. Nevertheless my campaign took a while to evolve to this place. At first it was very traditional Wilderlands of High Fantasy. Then we explored the first few levels of Dismal Depth, the Fight On! megadungeon and a bit of Barrow Maze. And when a player character fell into an “infinite pit” and another player character threw himself after the first one (picture), I decided to push it to a new level.

Oh, and the Google+ post was me saying that I was working out the domain stats for the region using the rules from An Echo Resounding (interesting comparison of An Echo Resounding and Adventure Conqueror King). I hope my players aren’t overwhelmed by my sneaky introduction of these domain rules. I think the two key phrases I heard last session justifying this move were “I think we’ll keep Monkey Island as our base!” and “Can we benefit somehow from reopening the mine on Monkey Island?”

2012-10-17 Traveller Maps for Campaign Wiki

Since I’m apparently going to use my Spelljammer-Planescape-Traveller map for a while, I added a way to make map display even easier on Campaign Wiki pages.

Write “Traveller:” followed by the UWP like this:

Traveller:
Tu Akhra 0404 D0602B3-1 P  As De Lo Lt R
Susrael 0503 B0604A4-1 N  As De Lt NI A
Nova Genova 0607 B867686-1 N  Ag Ga Lt NI Ri
Hinia Oot 0705 E060200-1 As De Lo Lt A
Monkey Island 0308 E064105-0 Lo Lt

And the result will be this:

Traveller and Spelljammer

Klick to switch to the map. There, you can click on the systems to get the wiki pages.

2012-10-11 Traveller, Spelljammer, Planescape

https://alexschroeder.ch/pics/7698864396_86ca1d8e91_n.jpg

I finally decided that the Astral Sea needed a map. One of the player characters decided to pursue his quest to revive Arden, the dead elven god. His corpse is being drained of its remaining life force by the sorcerer queen of the gray elves (Githyanki). His corpse is also drifting in the Astral Sea. A gate was found (a bottomless pit in the Barrowmaze), a ship was gained (pictured on the right), and now the party is sailing the Astral Sea Spelljammer style and finding places in the Planescape fashion. 👌

Anyway, I was wondering how many random encounters I should be rolling for any trips from A to B. I should draw a map, I thought. I remembered my Traveller Subsector Mapper. All I had to do was to generate an UWP for my locations.

Easy:

Tu Akhra     0404 D0602B3-1  P  As De Lo Lt    R
Susrael      0503 B0604A4-1  N  As De Lt NI    A
Nova Genova  0607 B867686-1  N  Ag Ga Lt NI Ri
Hinia Oot    0705 E060200-1     As De Lo Lt    A

I basically ignored the requirement for an atmosphere of 0 to generate the asteroid trade code. All these worlds have breathable air. Plugging this into the mapper:

Astral Sea

2010-09-23 Mixing Fate and Skill Challenges

I’m running a biweekly Diaspora game in a Traveller Subsector. The party had just crash landed on a planet after being shot down by a gunship using space combat rules and made it to the base on a sort of social combat map with the opponents being earthquakes, a sea monster, and a patrol of aliens. Inside the base, they saw the overgrown and partly disassembled remnants of the ship that had brought the alien infection to the system and decided they were going to hook their diplomat-hacker up with the central nervous system running the base. I asked the table whether they felt like another map and combat but Harald reminded me of another technique I often use: Just go around in a circle and ask each of the players what they’ll do to help solve the problem.

Four players, four rolls. I said you need at least two successes. First attempt by Thomas at finding a quiet corner fails spectacularly. The aliens get spin. Second attempt by Florian at fighting the immune system of the mega-organism fails spectacularly. The aliens get spin. Third attempt by Harald at hooking up the hacker fails spectacularly. The aliens get spin. Whoa!! The last roll comes up and I ask for the stakes. What’s going to happen when Jörg fails? I say he’s going to be taken over and integrated into the base if he fails. He says “w00t!?” He doesn’t want to take the consequences for all the earlier failures. Harald volunteers to take a severe consequence that would change his result into a success – “infected by an alien mind”. Yay!! Jörg manages to reprogram the alien factory in order to make the resulting ship something they can use. Victory!

As the session was about to end, I give the diplomat-hacker the following choice:

  1. will you try to get off-world as quickly as possible with the intelligence you gathered, ie. leave safely but without resolving the situation? No fight, no loot, minimal plot advancement.
  2. will you man the ship as soon as possible, head over to the wreck of the old ship to rescue an ancient artifact, delaying long enough that you’ll have to fight your way out of the system? One space combat, but save artifact.
  3. will you confuse the three ships in the system in order to gain enough time to penetrate the central nervous system of the base, eliminate the threat, and then try to get off the system? One personal combat, and one ship combat, but resolve situation.

They picked #3 – Alien 2 style. So proud. :)

If I wanted an easy way out, I wouldn’t be playing in the first place.
