Traveller

Have you seen the upcoming Kickstarter for The Serpent for Traveller? It looks interesting, and has some interesting inspirations.

As someone who has developed RPGs in the past I find that Mongoose Traveller 1e seems more cohesive. Maybe it is the expansion of the setting and additional options, or maybe that there seem to be new systems or mechanics constantly being added. Mongoose 2e seems too unmanageable. Is it just me?

I would like to wish a joyous Holiday to all sophonts across Charted Space and best wishes for a prosperous year!

Mongoose has a free christmas gift:

Orbital Reds is a free Traveller... Paranoia.... Travenoia mission, including everything you need to explore the utopia of Alpha Complex... using the Traveller rules set!

https://www.mongoosepublishing.com/products/orbital-reds

Orbital Reds is an adventure for Traveller set in the funniest dystopia around, Alpha Complex from the game Paranoia. It uses the same rules from the Traveller Core Rulebook but players take roles as Paranoia’s Troubleshooters trying to protect their utopia from an old weapons platform in orbit. It would be best if the team knew what space and orbit mean, but ignorance is not just bliss here. It is a survival trait.

Cluster Truck is a complete campaign that will see your Travellers take command of their own small craft, hauling cargo across a system. They will steal potatoes, get covered in frozen beer in deep space, take part in a history-making riot, uncover corporate skullduggery, and smash a blockade while confounding local law enforcement!

Mongoose just announced this on their Discord and I’m really excited about the theme!

For some reason I love space deliveries and regular life in space, so I’m looking forward to seeing what they put in there!

Just an FYI, as part of our migration off of our current host, it's become apparent that we're going to need to migrate our image hosting to object storage.

The change should be rather seamless from the front-end perspective outside of the migration window, but during the migration window, our image hosting capabilities will be offline. I'm not sure how long it will take (the current image hosting data is fairly large) so it could be a bit of a prolonged outage.

Text posts, and commenting should all work, image hosting and thumbnails will be broken. You can still link to external image hosting such as imgur.com, but it won't generate a thumbnail.

I'll update here when it is complete, but as of right now, i would plan for a potential multi-day outage.

I think I haven't shared this on the Fediverse yet.

The Cepheus Engine SRD has this nifty table on page 104 (chapter 5: off-world travel) where travel times are specified, at several G's of acceleration, for some common distances.

At some time I wanted to know how much time would it take to get to the Kuiper belt... but the table in CE's SRD stopped short of 7 Au.

So I made this page:

https://rpg20.com/index.php/misc/interplanetary

I also added a column where I specified the distance in light-seconds. light-minutes, light-hours, or light-days (because I find it useful to know when a radio transmission would ideally reach it's destination).

Hope someone else finds it useful.

A quick con report for last weekend's Travellercon/USA

TLDR: I had a lot of fun, great games, wish there had been more people there.

TravellerCon USA 2025 is coming this October 24-26th. It's at the Double Tree hotel in Lancaster, PA.

I missed last year, but I'm definitely going to run something this year.

For my Mongoose 2E campaign, I made my own custom GM screen, with only the stuff I found myself needing on a regular basis. It's 3 landscape pages, designed to be put in a customizable GM screen.

You can download a PDF copy, and the original Affinity files I created it with, here: https://polyhedralnonsense.com/2025/10/09/a-custom-gm-screen-for-traveller/

There is a new Ship Builder in Traveller Tools at Mongoose. There are some issues, but it's a great start.

One if the issues with Traveller's technology system is the lack of efficiency and progression. As an example, Vacc suits in Traveller rarely get lighter, less expensive, or add additional features. This true of pretty much all components, equipment, and weapons. There is no systematic way to reduce cost, weight, or manufacturing time. There is no benefit to additional capabilities and if there are they are always more expensive.

I do recall in the old days a supplement or article that discussed technological progression of vacc suits, and that may have been DGP. There was even a modular build system for custom vacc suits in CT JTAS.

Should components and equipment get lighter, cost less, or add capabilities. Not just vacc suits as an example, but all technology?

Just one man's opinion, but I thought it would be a neat discussion.

Best regards.

The original post says:

Today is the 20th anniversary of the launch of TravellerMap.

Since I'm lazy, go read the 10th anniversary post for some history.

Do you have a favorite 400-800dton bespoke Adventure Class ship?

Mine is the Scout Trader, this is a modified Type R given to small detached scout crews to trade (and gather intelligence) on the periphery. They become especially important after the Fifth Frontier War and into the Hard Times as the Imperium is in desperate need to monitor the area.

On another forum people were asking about everyone's first RPG experience. Now my story involved D&D but only about six or eight weeks later I played the 1977 version of Traveller. I was 11 years old.

My question is, what version brought you into Traveller? Was it little books, or color covers? Was it before the Fifth Frontier War, or during the Virus?

Please share.

Guarded behind a tall steel wall covered in barbed wire is a small military base home to a small reconnaissance force. This place is characterized by the loud chatter of soldiers, large dust particles in the air, and the overwhelming smell of diesel. Can your players infiltrate this base?

This base includes a control room, officer's quarters, infirmary, chow hall and kitchen, barracks, armory, and a storage room. A couple port-a-potties lie to the south, which are always in use. Two guard towers scan the land for threats.

This map pack includes Modern, Cyberpunk, and a Post-Apocalyptic variant. Each variant also comes with a rooftop.

Download the base map for free here.

This is the best I have found.

Currently working on designs for some larger "small craft". variant Shuttles, a Marine Dropship, and a larger Marine Assault Carrier. The dropship is 40 dton, and the shuttle variants are 100, 200, and 500 dtons, the assault carrier is probably 400 dtons. What is the range of small craft in your Traveller universe?

Zozer recently released a version of their Kosmos 68 setting for Classic Traveller. It's based entirely on old Soviet sci-fi. The new version used the same page design and style as the original LBBs.

I've made a modified version of my Classic Traveller sheets to match this setting. They're fillable and free to download
