Marc Miller's Traveller

The following is my review of the fourth edition of the Traveller rules, entitled Marc Miller's Traveller, abbreviated T4. The review begins with an overview of the entire system. Following that, there is a chapter-by-chapter review. Finally, I give some general feelings, a numerical rating for the work, and a recommendation.

System Overview

T4 has errors; some are serious, most are not. T4 is not Traveller: The New Era (TNE) Second Edition; the only thing it has in common with TNE is the starship systems (and even that has been changed from Fire, Fusion, and Steel (FF&S)). T4 truly is, as Imperium Games (IG) claimed, "Classic Traveller (CT) updated based on 20 years of RPG experience." Take The Traveller Book (TTB), add a new task system, some more character classes, a new die-rolling convention or two (1/2 dice, X- targets instead of X+ targets), a consolidated and updated skills listing, and the aforementioned modified TNE starship creation system, and you'll have the essence of T4.

The book begins with a short history of the Traveller game, outlining the early years, MegaTraveller, Traveller: The New Era, and the fall of Game Designer's Workshop (GDW) and FarFuture Enterprises (FFE)/IG's subsequent actions. It's a good (if short) summary, and those new to the Traveller system will probably get a good feeling from knowing the system they're buying has such a long history. Also included in this section is a sort of Mission Statement for Traveller, stating Marc Miller's desire to return to a simpler gaming system while allowing for increasing complexity for those who desire such, through additional materials.

Chapter 1 (What's in this Book)

This material is mostly pulled from TTB. Topics include, What is a Role-Playing Game, how to referee, etc. In short, this is the section included in every RPG ever made.

Chapter 2 (Character Generation)

The new system is a cross between the basic and advanced CT systems. For example, careers are resolved in four-year terms, but the character now receives four skills per term instead of one (plus possible additional skills for commission and promotions). This, coupled with the pre-career schooling options and four to seven initial skills make for characters well able to compete with the best characters generated under any previous Traveller system. There are eight schooling options and ten main careers, allowing for a wide variety of characters to be created.

There are other differences between the T4 and CT systems. Under T4, there are no longer survival throws. Instead, a throw is made for injury. If an injury results, the character is discharged honorably from service, is healed, then begins his or her adventuring career. A minor difference is a change in terminology from "Reenlistment" to "Continuance," which has less of a military connotation.

Unfortunately, this section has many typos (as do almost all sections of the book). Worse, there is a serious error: the mustering out rules do not match the character generation tables. The rules state that the character receives additional rolls on the Cash or Benefits tables based on his or her rank achieved. Rank 1-2 yields one additional roll, Rank 3-4 yields two rolls, and 5-6 yields three rolls. Yet on the character generation tables, ranks proceed from E1 to E10, and from O1 to O10 (or O7 in one case). While CT aficionados will know what is meant by ranks 1 through 6, new players will undoubtedly be unable to reconcile the text with the tables. [Note: An errata page which clarifies this can be found at http://www.stl-online.net/vanya/default.html. - Ed.]

There is another error in this section. In the services portion of character generation, the skill tables do not have cluster/cascade skills listed in bold (they are listed in bold in the schools/colleges section, though). This will confuse people at first, until they memorize which are clusters/cascades and which are not.

Overall, the characters generated under this system will have more skills and higher characteristic scores than those generated under any previous system. Whether this is good, bad, or indifferent depends on the individual. I personally like the new system.

Chapter 3 (Skills)

The skills list is about the right size, giving players enough skills to easily differentiate their characters without giving so many that it becomes unwieldy. The skill descriptions are good, providing enough detail to give referees an idea of which situations each skill will be useful in.

The Skills List and the Skills Descriptions are supposed to have some skills in italics, which is to connote those skills which may be used at level-0. Unfortunately, no skills are listed in italics. Fortunately, such skills are denoted in the Skill Descriptions section by having the word Default in their heading. This is less convenient than the italicized Skills List method, but it is not a serious error.

Chapter 4 (Tasks)

This chapter is only two pages long, which I count as point in T4's favor. Many games are plagued by overly complex task systems that list dozens of die modifiers. This task system does not succumb to that failed methodology.

The only thing controversial about the Task System is its reliance on 1/2 dice. That is, in some situations it will be necessary to throw a number of dice, designating one as a "half die." The roll made on this die will be halved (rounding up). Some players do not like this method any more than I enjoy an overly complex task system. Overall, I think this may cause some slight decrease in sales, but I think the rest of the system is robust enough that those who really want to play Traveller will put up with the 1/2 die rolls.

Chapter 5 (Ground Combat)

The combat section looks good. 8 pages of text, one page of tables, and it covers just about everything you'd want it to (in a basic book), from hand-to-hand to artillery, tanks, robots, and other forms of ground combat. It is possible to cover all of this (in a basic way) in 8 short pages because of the robust task system. I'm impressed.

You can still tell Traveller has its roots in wargaming. The original rules shine through in this section, and their flavor is retained. However, the consolidating effect of having a task system has vastly simplified the combat rules over what appeared in CT. Once you memorize the task system, combat will go very quickly.

The only error I found in the section is in the discussion of explosives. They don't mention whether a grenade is thrown at a target hex or a target individual. Since the system uses range bands, I guess I can see why they didn't mention it. But, it'll be hard for inexperienced players to resolve hand grenade attacks. They can figure damage, but not to-hit. Most will probably be able to puzzle it out though.

Here is a list of things I like about the combat system:

  1. Multiple actions: A character can now make a number of actions each round up to his or her related characteristic score, but at a penalty. A person with Strength 8 can make 8 Brawling attacks per round, for instance, but each attack will have relatively little chance of succeeding (unless the character is very highly skilled).
  2. Called Shots: You can do a called shot for increased damage (two kinds), decrease damage (two kinds), or to disarm.
  3. "Holding" your actions is covered well.
  4. Special Rules: In addition to the Tactics Pool and Endurance rules that are familiar to most of us, there are also Strength and Dexterity Pools. Strength pools allow one to increase the damage done by non-ranged attacks. Dexterity pools allow one to avoid being hit by non-ranged attacks (no dodging bullets, darn it!).
  5. Initiative: Initiative is done more logically (I got a taste of this in the Starship Battles game, and it works well) now. The side that wins the initiative moves last but attacks first. That way, they can react to the other side's movement, then fire attack before the other side does. This is more playable than realistic, but from experience, I know it does work well.

Chapters 6 (Equipment) and 7 (Vehicles)

The equipment sections (comprising the Equipment and Vehicles chapters) are well done, and have fewer typos than the first few chapters (the character creation chapter has the most typos). There is a sampling of equipment given in these chapters, much the same as that given in The Traveller Book. The full list, of course, will be in the Central Supply Catalog supplement.

There are also side-bars giving some examples of specific models of vehicles with very detailed descriptions and specifications. I like this. (incidentally, the book uses side-bars the way they should be used: sparingly.)

The basic equipment section has a few new items in it (including a non-lethal weapon and a not-very-lethal weapon, both commonly used for personal protection a la mace/pepper spray and stun guns).

The pictures given of various pieces of equipment are well chosen. The text is well-written and informative. I usually skip equipment sections until I need a specific item, but this one has some gems in it that make it worth reading.

Overall, the equipment chapters were done well.

Chapters 8 (Spacecraft), 9 (Space Travel), and 10 (Space Combat)

We all know about the starship design sequence (developed by Guy "Wildstar" Garnett, and dubbed the Quick Ship Design System (QSDS)), so I won't go into that, except to say that IG, in attempting to squeeze this last-minute-change into the book was forced to put the tables in completely out of order. The Hull Table, although it should be consulted first, is on the third page. The Thrust Plate Potential table appears a few pages later than the Thrust Plate Drives table, even though those tables should be consulted together.

The section on traveling, Lesser Known Aspects of Space Travel, etc. are all pretty much right from The Traveller Book. The big news is the space combat system. For you space combat fans, please remember that this, like all the systems in the book, is the basic system. You won't be stuck with it.

That said, the Basic Ship Combat system is excellent for those of us who are fans of ship combat, but who don't want something that takes all day. This system is simple, smooth, and streamlined. It is actually easier than the Traveller Starship Combat system alpha-tested at Gen-Con. It's a stand-and-blast sort of system, in short. I applaud the inclusion of this system. IG and FFE did the right thing.

I look forward to the release of the system shown at Gen-Con, but this will do for now. More importantly, this system will allow new players to jump right in and engage in starship battles. It will whet their appetites for the (two? three?) more complex ship combat systems to come.

Chapter 11 (Psionics)

This is mostly straight out of The Traveller Book, with the notable addition of a Psionicist prior service! That's right, there is a somewhat-hidden 11th character type in T4! (I was rather surprised to run across the generation table in the Psionics chapter.)

Also included is a Telekinetic Damage chart, which shows just how lethal such a skill can be. The maximum damage listed is 33D!!

Chapter 12 (World Generation)

This is almost completely a copy of the same chapter from TTB. Since there are no major changes, there's nothing to review. Sadly, there are no forms provided for use with this section.

Chapter 13 (Encounters)

This is a combination of the Encounters and Animal Encounters chapters from TTB. The notable exception is an inclusion of short (1/2 to 4/5-column) descriptions of each of the major and minor races of Traveller. Also included is a bit of info on including aliens in a Traveller campaign (administering them, role-playing them, creating new ones, etc.). Interestingly, the example encounter table from TTB was used. In TTB and in T4, it is labeled as the encounter table for Regina, which won't be contacted for quite some time after Milieu 0. That one will probably confuse some new players! "Where the heck is Regina on the Core Subsector Grid? Eh, I'll just call one of these unnamed planets Regina. What could it hurt?"

Chapter 14 (Referee's Introduction)

Once again, this is mostly taken from the Introduction in TTB. Also included is the Character Experience section, which has much better allowances for skill improvement, learning new skills, and improving characteristics (somewhat like the system I proposed on the Traveller Mailing List several months ago).

Chapter 15 (Running Adventures and Campaigns)

This stuff is right out of the Referee's Guide to Adventuring from TTB, right down to the well-known "basics, push, pull, gimmick, enigma" method. Once again, not much to review here.

Chapter 16 (Trade and Commerce)

This is right out of Book 7, Merchant Prince. We're back to trade goods being designated C-9 Ag Ni Cr 7,000. I'd hoped for something more, but I guess that, like the space combat enthusiasts, I'll have to wait for the appropriate supplement.

Chapter 17 (Exit Visa)

Exit Visa is one of the adventures that was included in TTB. It has been updated to make sense under the setting and rules of T4 (i.e., different equipment, different date, etc.), but is otherwise very similar to the original.

Chapter 18 (Rubicon Cross)

This is a completely new adventure. It is a well-crafted scenario, and should serve well as a means of getting new referees and players excited about Traveller.

Sadly, unlike TTB, no other adventures were included. Also, no mention was made of "Basic Traveller Activities," which in TTB offered a list of suggested solo activities for players and referees to engage in between sessions.

The Rest of the Book

The final few pages include: Core Subsector data, Core Subsector Grid, the Traveller character sheet, some Library Data (right out of TTB, once again) and a pretty good Index.


On page 13, in the What's in this Book section, they kept the paragraph on forms from The Traveller Book:

"Scattered throughout several chapters are various prepared forms. One is used to record the specifics of the character, for instance. Another records data about a starship. The forms provided are intended for use by the referee and the players as they generate information during the game. They have been printed on the page for maximum ease of photocopying. Once two copies have been made, they can be positioned side by side on the photocopier and multiple copies can be run off."

This is almost completely wrong. Yes, there is a character sheet. It takes up a whole page. Making two copies, as they suggest, makes no sense for ease of further copying, since it takes up a whole page and not 1/2 page as in CT. Furthermore, the starship form is tiny, about 3 inches by 4 inches. It is toward the binding on the page, and the page has other information on it which you would not want to copy. Hardly suitable for copying unless you go to rather more effort than should be required.

I have found no other forms in the book. Most notably missing are the Sector Map Grid and the Sector Data Form.

IG or someone else should rush a Forms Pack to the market, so that players and referees who don't have the CT forms can more easily keep records, generate sectors, etc.

Rating the T4 Book

My overall score for T4, if it had been completely error-free: 100 out of a possible 100. (This assumes no typos, no other errors, and the inclusion of better/more forms.) [That is, I think the ideas behind the book are rock-solid.]

My overall score for T4, if it had been without the errors in Chapter 2 (mustering out rolls), but otherwise unchanged: 92 out of a possible 100. [Meaning that all of the errors I have found, excepting those in Chapters 2 and 3, are trivial, saying only to the reader that IG was sloppy and/or rushed in preparing the book.]

My overall score for T4, errors and all: 87 out of 100. [Meaning that the error in chapter 2 is serious enough to knock their score down considerably, but they still earned a solid "B" grade.]

My Recommendation:

Read the book and make your own decision, above all. I've tried to give people a feel for the system, but there's nothing like seeing it for yourself. That said:

If you are a fan of CT and would like to see new products for your favorite game, this is probably the system for you. The plethora of new products planned for T4 will almost certainly satisfy every type of player.

If you are a fan of MT but wish it hadn't been done quite the way it was, this may be the CT update you've been wishing for since 1987.

If you are a fan of TNE, this is probably not what you are looking for. If you like TNE's starship systems a lot, but like some of the things about CT and MT, you may enjoy T4. But if you think TNE is the best incarnation of Traveller you've seen yet, you probably won't like T4. (This one is an almost uneducated guess, as I have never played TNE and I've only read the rulebook for it once. But, comments from TNE players at Gen-Con, while perhaps not representative of all TNE players, concur with my opinion expressed above.)


I believe T4 to be a worthy successor to the Traveller name. There is only one serious problem with the book: the number of mustering out rolls received by commissioned characters. This, however, should not significantly affect the playability, and therefore sales, of the game. A simple, one-paragraph errata sheet will correct this error. Clearly, that is far better than GDW did with MegaTraveller.

Please, go to the store, give the book a careful examination for yourself, and make you own decision. I think you will like what Imperium Games has produced.
