Welcome to MyGURPS, a page full of resources and information for the GURPS® Fourth Edition roleplaying game from Steve Jackson Games.
Herein you'll find some of the house rules that I use (and heartily recommend) for the newest edition of GURPS, various resources and articles that you might find useful, new data files for the GURPS Character Assistant software, and some of the GURPS books (and other Steve Jackson Games products) that I've reviewed on RPGnet. You'll also find resources for other games near the bottom of the page. And if you'd like to know more about me, click here!

This section is for resources for GURPS GMs or players that I've created or helped with. It's also where you'll find various worked examples of what can be done in GURPS, from sample characters to writeups of super-powers or other abilities.
1. Historical Folks Conversion for GURPS Fourth Edition.
A few years back, Brian C. Smithson released Historical Folks as a free (unofficial) supplement for GURPS Third Edition. MyGURPS is proud to host the Fourth Edition Conversion of this incredibly useful e-book.
2. Revised GM Control Sheet (MS Word).
I've always liked the overall layout of the official GM Control Sheet, but find that it could use space better. This version gives each character two lines of info, keeps all of the attributes together, has a spot to track both HP and FP, gives you two lines each for reaction bonuses and DR, and even has room left over for notes. The lower half of the sheet is basically unchanged. It's all done with tables, so you can fill it in on the computer and print it out. Click here for a snapshot of what the sheet looks like, or click on the title to download the MS Word file.
Update: The GM Control Sheet is now available in PDF format, thanks to Eduardo Alvarez. He has created two different versions -- a standard PDF and one with editable fields so you can still fill it in on the computer if you don't have MS Word.
3. Creating a "Super Archer".
Archers like Green Arrow and Hawkeye have been a part of the supers genre for some time. Using Alternative Attacks, it's remarkably simple to create all of their trick arrows and then some.
4. Diabetes as a Disadvantage.
A brief summary of the effects of Type I and Type II diabetes, followed by how to build each one in GURPS using existing disadvantages. Find out why Dependency (Insulin) is the wrong way to approach this condition.
5. Using "Either/Or" Limitations.
Have you ever needed to build a power that was affected by either one limitation or a different one, but not both at the same time (e.g., an attack that doesn't have its full range except in direct sunlight)? Though it isn't immediately obvious, the rules do officially support such a thing, and it's surprisingly easy to do.
6. Super-Effort for Striking ST.
GURPS Powers added a new Super-Effort enhancement so that bricks and telekinetics could make amazing lifts in high-powered games. Here's a similar enhancement for Striking ST that makes it a more reasonable purchase in games offering Innate Attacks.
7. Cosmic Power for "Super Gadgeteers".
A set of ground rules and a modifier for characters who use their Modular Abilities to build "super gadgets" (like "Density Nullification Rays" and "Teleportation Belts"). Boils everything down to one modifier, one roll, and a few simple rules.
8. Upgrading the Magic System.
A few simple adjustments and optional rules that I've added to the GURPS magic system. Balancing Ritual Magic is a minor tweak to prevent the point-crock abuse that seems to invariably occur when the ritual magic rules are used in a game. Modifying Spells is an easy answer to the question, "How can I make my fireball homing?" Long-Ranged Magic is a worked example of modifying spells, to allow for a world in which mages aren't limited to just a few yards of range.
9. Heavier Weapons for Stronger Characters.
Since every melee weapon has a minimum ST (and thus a maximum ST) rating, it can be useful to know how to raise this value for very strong characters. Here are some simple and fast guidelines. (Also includes a tangent on quickly calculating armor weights and such for humanoids with non-zero Size Modifiers.)
10. Infinity's Table of Organization for Infinite Worlds (PDF).
Infinite Worlds is easily one of my favorite settings, though trying to keep track of how all of the departments interact can be tricky, especially when it comes to remembering exactly where the United Nations fit in. So I've drafted up an "org chart" for Infinity Unlimited, including page references for every group listed. The second page is a brief summary of each group, intended to be printed on the back side -- this makes for an excellent player handout.
11. Absorption Revised.
The current rules for Damage Resistance (Absorption) produce some odd results, such as paying 4 character points for the privilege of being able to temporarily add 1 character point to a single ability when attacked. I've taken it apart and rebuilt it -- though not quite "from the ground up."
12. "Upon Death" Abilities.
I present some guidelines for building abilities which are linked to the death of the user, whether that means, "I can use it, but at the cost of my own life," or, "It triggers automatically when I die." There are a variety of approaches which can be taken, depending on exactly what the effect is, though fortunately they're all pretty straightforward.
13. New Techniques.
A repository of new techniques that I've created, both ex nihilo and using the system in GURPS Martial Arts. A bit sparse at the moment, but I will be adding to it every time I come up with something I feel is universally useful.
14. Veterans of the Weird West.
My conversion guide for playing Deadlands using GURPS Fourth Edition. This is based on a loose combination of original Deadlands, the newer Savage Worlds take on it, and some of my favorite things about how GURPS does things.
Here is where my thoughts, ramblings, and pontifications on GURPS end up. Many are of a rules-related nature, but don't really count as house rules, either because they're only guidelines or they focus on examining a rule rather than changing it. Others are just opinions or experiences that I felt were worth sharing. In all cases, I hope you find them useful.
1. Yes, Virginia, You CAN Afflict Yourself.
In an attempt to put an end to the confusion about using Affliction to give yourself an advantage, I got to the bottom of how it's really supposed to work. Read why you can zap yourself with your own shrink ray, but why you may not want to.
2. Innate Attacks, Wuxia, and You.
My thoughts on Martial Arts and allowing Innate Attacks in a cinematic wuxia game, along with some guidelines and limits that work well for preventing such things from harming the flavor of the campaign.
3. Just Say No to Mass Combat Systems.
Mass combat systems have their place -- specifically, when the PCs initiate a huge battle with another sizeable force. But not when the PCs are just soldiers in a larger war. Read on to see why the question of "who wins" is a meaningless one -- and why the battle itself should never take center stage.
4. Nipping Problem Allies in the Bud.
While few people actively set out to abuse the Ally advantage, certain designs can prove quite problematic if the GM isn't prepared for it ahead of time. After sparking a discussion about this with several veteran gamers, I've tried to condense the key issues (and solutions) down to a single article.
5. Preserving the Polarity of Weirdness Magnet.
One of my pet peeves is the persistent meme that Weirdness Magnet is hardly a disadvantage. Both players and GMs often seem to treat it like anything from a minor inconvenience to an actual advantage. For those gamers, this part-rant, part-article attempts to present Weirdness Magnet in a new light.
6. Gun! Versus Pistol.
A short article, based on a playtest email, which addresses the utility of Wildcard skills. Some gamers see each Wildcard skill as restricted to a fixed list, instead of as a cinematic "uber-skill." This is especially prevalent with the Gun! skill, which I address specifically here.
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.
