  • Sci-Fi RPG systems/settings/core rules

  • Okay you beautiful nerds, name the thrust assembly. Dip pen, January 2025.

  • Streets of Mos Eisley

    In the post where we're listing all the Sci-Fi games we could come up with, there's a distinct lack of PBTA games. And I get it... there's probably too many to list.

    But even if I have my Sci-Fi needs fulfilled (perhaps for the moment, and for the most part) there are a few games that I'd still like to play some day. This is one of them.

    Why? Because it's straight and to the point. I tell myself that one of these days, when I think of a plot for a Star Wars Worlds one-shot adventure, I can grab this and get rolling in 5 minutes.

    A lot of people dislike PBTA, but I actually find it valuable. I think PBTA is particularly good at short adventures and one-shots. For longer campaigns? Not so sure. One of my favourite (non-scifi) games, Kult (!kult@ttrpg.network), uses PBTA in its newest version. They did try to think ahead to advancement for longer campaigns, but would it be enough for a regular multi-year group? I don't know.

    Just from this sm

  • Scout (tactical)

    This is the completion of what I had in mind for the "tactical map". I must say, I didn't come up with the concept, nor the color palette. I got that from an image I downloaded from somewhere... But I don't remember where. Maybe the Traveller Discord?

    Anyway, the main image is very much tied to the M2E version of Traveller, but back when I made this image I hadn't fully commited to one ruleset (I'm both a heavy houseruler and heavy improviser).

    So here's one for Cepheus Engine:

    And here's one for Cepheus Deluxe:

    The Range tracker doesn't make sense for CD rules, but it looks cool and I didn't know what else to put there. :)

  • To railroad or not to railroad?

    User Monomyth posed an interesting question on the Traveller discord that I wanted to replicate here:

    hi team, just a quick discussion based question with no right answer; if youre running a game, and the players decide to veer off course into something completely out of left field (such as going to a planet you do not have prepped), is it appropriate to come up with some "delaying issue" so you can have it ready for next session?

    Transposing to other settings: what do you do when the players go off-script?

    I can summarize some answers we’ve got on that server, but I don’t want to prime your answers from the start.

  • I've been working on a new/custom sci-fi RPG system for the past year or so

    Just putting this out here to share some of the work I've been doing and to create some content for this community. Also because I'm not quite ready to share the full thing with larger groups.

    I've mostly been creating a system for fun, and to exercise my art/design chops. I've got the base rule book done, but I was wanting to create a "pack in" adventure to go with it, which i have yet to start.

    I'll include some screen shots as I go along and give some of the details around the setting and system. The title I'm currently running with is "Stellar Knights of Pendragon" and it is a sci-fi RPG based off of the myths of King Arthur.

    Stylistically, I'm trying to make the book look like something from the 16-bit/SNES Era of video games, mostly because I'm pretty ok at pixel art (and not much else), but also because the concept sounds like something you'd see on the sega genesis or SNES

  • Range tracker

    While learning Traveller I came across this video where he explains how to use a ruler to keep track of distances relative to other ships.

    I liked the idea, but found a 20-inch ruler, just up to long range, a bit impractical. So I created this tracker.

    I used black background and neon colors because I thought I would be playing with a VTT, but in the end I've only played in person. So I also have this PDF, in Ledger/Tabloid (11" x 17"). I don't think you'll find a printer that's able to print up to the very edge, so I'll let you decide if you'd rather scale it below 1" per square or just accept cropped stuff on the edges.

  • My attempt at the hauler from Flatlined

    This was just a test I made while trying to get the hang of the Cosmorgapher3 addon for CC3+.

    Basically I just took Seth Skorokowsky's map (linked in the comments of his Flatlined review) and tried to retrace it.

  • What's your go-to seed/trope?

    A trope, a seed

    Back in the 90s, my GM ran a "Thieve's guild" adventure for D&D. You know the drill: something's going on in town, the PCs track a trail and find a secret entrance to a dungeon, they realize there's a thieves' guild creating the trouble, they deal with it and get the treasure. Then I found a few fan-written "thieve's guild" but had no resemblance to my friend's, just the main concept. Years later, while trying to wrap my head aroung Mage, I asked a friend what would be the "thieve's guild" equivalent for Mage (he said it was "defend a node"). I now call these "seeds", or maybe tropes (but I wouldn't call them that for a long while).

    The milk run

    Fast-forward to just a few years ago... I had discovered Shadowrun and felt dry with ideas for getting started. I googled for a while and came up with a reddit post recommending a "Milk run". Basically, have the crew tasked with snatching something fr

  • Favorite sci-fi RPG settings?

    What are your favorites to play on? Anything valid, be it a published RPG setting, an adaptation you did of other media (book, game, movie), a mashup you or someone else create, etc.

  • Small Tanker

    I created this as a prompt for a small one-on-one adventure for Traveller. A very simple adventure where the player found a gig where she was tasked to go scoop hydrogen from a gas giant.

    This was also my first attempt at drawing a ship.

  • Relay station

    cross-posted from: https://ttrpg.network/post/13455043

    Might as well cross-post this here.

    Back to the map: I created it over a year ago, but hadn't shared it on Lemmy. As with many Traveller maps, a square is meant to be 1.5m (close to the 5ft used in most fantasy genres).

    This space station design was commissioned, to the lowest bidder, by a local planetary government much to the horror of the IISS. And it shows that is was done on a budget. Sure, the comms are prefectly suited for a relay station, but it often feels like a death-trap. Just ask any of the employees.

    Made up of four general-purpose modules glued together, and then fitted to accomplish it's purpose, any outsider would think everything should work fine. However, many bottom-credit decisions were made and it might be just a matter of time until something goes wrong.

    For instance, the original design had a fourth spoke for an

  • Thamber system

    I made this map a while back, for a Traveller game we were playing.

    It's Thamber, in the Solomanin Rim sector, Ultima subsector. There's no canonical system defined AFAIK, so I used https://www.travellerworlds.com/ to generate a new star system. Then drew the info onto Campaign Cartographer 3+.
