These are the house rules and articles which were written specifically for GURPS Traveller. Traveller is the epitome of a "classic sci-fi" setting, with a rich history and a universe clearly tailored to gaming. It also happens to mesh perfectly with GURPS -- an example of a great system supporting a great setting.
1. Building Jump Drives with Warp.
Just a mental exercise that occupied me one night; I thought it might be of interest to others. Making Warp work like a Traveller-style Jump Drive is actually easy; the tricky part is ensuring that the jump distance makes a difference in play. (Also includes a tangent on easy rules for calculating move relative to the speed of light with Enhanced Move (Space).)
2. Updated Traveller Racial Templates
I was disappointed that GURPS Traveller: Interstellar Wars didn't feature the templates for any major race except the Droyne (and they were oversimplified.) So I took it upon myself to convert them -- not just converting over each trait, but rebuilding them with the tools of the new edition to (hopefully) truly capture their essence.
3. Psionics in Traveller
This is a breakdown of the power groups (and the abilities which they comprise) which are available to psis (and anti-psis) in my Traveller games. It includes suggested limits on power levels and rules for Unusual Backgrounds and developing psi. There are also notes on Droyne psi and Zhodani characters.
4. Using GURPS Spaceships in Traveller
The simple GURPS Spaceships rules are a natural fit for Traveller games, as they give the ship just enough detail to be useful, but not so much that flying the ship turns into a wargame. With the rules tweaks and judgment calls on this page, I think it's pretty close to a perfect fit. Update: Also includes my rules for the Ship Owner advantage in Traveller.
I have become a big fan of the GURPS Character Assistant program since its Fourth Edition release. It is versatile and quite customizable, even if the syntax does take some practice. So here's a little bit of my handiwork, from complete custom GDFs to patchwork creations, along with instructions for ease of installation.
PK's House Rules[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
If you like my house rules (above) and would like to incorporate them into your game, here they are! I tend to tweak this file a lot, so come back often. By left-clicking on it, you can check the Last Modified date (it's right there at the top) and see if you've got the latest version.
This file also includes some of the other, simpler entries from my site. For example, it has the Diabetic disadvantage but not the Super Archer power writeup. It's fully documented, so if there's any rule that you don't care for, it can be edited out easily, even if you don't understand anything about GDF syntax.
Balanced Ritual Magic Rules[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
This data file implements the two tweaks that I recommended to balance Ritual Magic. Path skills no longer default to the core skill and all spells are Average techniques instead of Hard. It also includes a very basic template for mages who want a starting level in every useful Path skill with one click.
You may also be interested in this text file which contains the corrected prerequisite count for all of the spells in Magic; I distilled it from the official Variant Ritual Magic GDF.
GURPS Mysteries 4E[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
This started out as an unofficial data file for the excellent GURPS Mysteries (a PDF which is available as an electronic download through e23). It has since been made official and is part of the latest data file update available at the GCA support page. It adds all of the new traits, though I'm still working on the professional templates.
Talents and Wildcards: A Compilation[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
I love Talents. If you're at all like me, you've wondered if it's worth the extra loading time and memory to add in all of the "source book" GDFs just to give your players access to the Talents therein. And then there's all the ones people have created -- a search through the forums will turn up countless homebrewed Talents, many of which are at least as good as the canonical ones.
So I created this file. It includes the official Talents from various GURPS sourcebooks as well as my favorite homebrews from the forums. Add this to your GCA loadout and you'll have all the Talents you'll ever need. (Hint: Click on the drop-down box at the top of the Advantages menu and select "Talents" to see a full list.)
As a bonus, this file now includes a list of Wildcard! skills, both official and homebrewed, with full descriptions of what each one covers. As with the Talents, you'll want to select "Wildcard!" from the drop-down box at the top of the Skills menu once you've loaded this file.
Features Talents and Wildcard! skills from GURPS Fantasy, GURPS Mysteries, GURPS Infinite Worlds, GURPS Banestorm, GURPS Space, GURPS Traveller: Interstellar Wars, and Transhuman Space: Changing Times.
Traveller Racial Templates[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
This file reproduces my Fourth Edition conversions of all of Traveller's major races. It also features a few traits (Unusual Backgrounds, Secret (Psi), and Patron (Psionic Institute)) to facilitate the creation of a psionic character. If you use the regular character sheet, I recommend choosing the option to print the racial template details (in paragraph form) above the advantages and disadvantages. I've tried to optimize the descriptions for that choice.
Our Star Trek Game[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
Someone requested this, so I'm making it available, though was never intended for the masses and is thus not internally documented. This is the data file for the Star Trek game our group is currently starting. As of this writing, it has racial templates for the Klingons, Ullians (they were in a single TNG episode), and an amphibious player-created race called the Nadissians. It also features professional templates for Starfleet Enlisted, Starfleet Officers, and Klingon Marines, as well as what I think are balanced skills and rules for the bat'leth.
GURPS Powers: Divine Favor[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
A complete data file for GURPS Powers: Divine Favor. Includes the titular advantage, all of the learned prayers, and the new versions of Blessed and Power Investiture.
GURPS Monster Hunters 1: Champions (PARTIAL)[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
This is the beginning of a GDF for GURPS Monster Hunters 1: Champions. It includes all of the boring stuff -- the individual new traits, the equipment lists, and so on. It's missing a few things, but most notable are the new character and racial templates. This will help to give a head start to anyone working on those templates, and it works just fine in itself for those who'd rather use the templates in the book rather than via GCA's interface.
Skillful Character Sheet[ DOWNLOAD FILE ] [ INSTRUCTIONS ]
I created this for a GURPS Martial Arts convention demo game, and realized that others might find it useful. It's based on (and directly edited from) the normal GURPS character sheet, but with several additional options to alter the content.
You can remove the "Languages" box and/or the "DR and Cultural Familiarity" box to make more room for skills. In addition to shrinking the "Notes" box to make more room for Hand Weapons, you can also shrink the "Ranged Weapons" box for even more room. Finally, you can prevent Bite from showing up as a weapon, to save room for more common attacks.
Note that the Instructions (above) are slightly different for this file.
If you encounter any errors while using any of these data files, I'd appreciate if you'd tell me on the GCA forum or shoot me a private message.
