The Gygax Rule for GMs – All you need is good rules and good books

In my gaming pantheon, I clearly play wargames first, other boardgames second, and role playing games (RPGs) a distant third. Spending-wise, I have bought very few RPG products since April. In the past month I came close to buying two new RPGs but didn’t. Along the way I learned a valuable lesson taught to me by no other than the Godfather of RPGs, Gary Gygax. Gary reminded me that RPGs are inherently a personal creation; if a product is “not quite right” there are tools available to “do it my way.”

The big RPG splash of the month was the Kickstarter launch of The Expanse Roleplaying Game from Green Ronin Publishing. The project currently (as I write) has over 3,330 backers pledging upwards of $239,000 against goal of $30,000 – and 24 days to go.

I initially pledged to support at the Ship’s Boat-level which is $20 for the pdf version. I then downloaded the free Quickstart pdf and took a look. I am no hard-core The Expanse fan but I generally like the universe. I initially missed the books and became acquainted with the setting through the TV series. After looking at the Quickstart I mulled it over for a few days and then cancelled my pledge.

First, the Quickstarter did not appeal to me; indeed, it actually turned me off. My initial negative reaction was to the artwork. I think my expectations are biased from the TV series and the artwork in the Quickstarter just feels too different. More importantly, it is not what I see as evocative of the setting. It almost seems too cartoonish to me whereas I imagine The Expanse though a more hard sci-fi lens.

Secondly, the RPG core mechanic (based on Green Ronin’s Adventure Game Engine – AGE) just didn’t capture what I think feels like The Expanse to me. I admit I was a bit confused at first because I was expecting to see the Chronicle System used in A Song of Ice and Fire Roleplaying Game which is my only other exposure to Green Ronin. I really like the Intrigue Mechanic in Chronicle and it perfectly captures (is evocative of) the Game of Thrones setting.

Looking at the Quickstarter pdf, I weighed my pledge and thought about what I was getting. I decided that I actually already have a version of The Expanse RPG. I actually have two of them, both from Zozer Games, and both using a system I am comfortable with (Cepheus Engine):

  • Orbital: 2100 – “Realistic spacecraft, using reaction drives and rotating hab modules for gravity. Orbital is set in our own Solar System and has a real hard-science feel to it.”
  • HOSTILE – “A gritty near future setting inspired by those late-70s and early 80’s movies like Alien, Bladerunner and Outland.”

I seriously weighed getting The Expanse RPG if not for the system then for the setting material. Then I (fortuitously?) came across this article by Gary Gygax himself and published in 2001 where he talks about author Jack Vance and the Dying Earth books. In particular, Mr. Gygax writes:

There is a truly great advantage offered to the Game Master when devising a campaign set on the Dying Earth. It is not highly detailed. There is no strict timeline laid down. All that has happened before is not “recorded”, nor is there an accurate gazetteer of for the world. What magic operates? Nobody can say or guess, because in the long eons of the Dying Earth’s history, likely every form possible was discovered, used, and then forgotten…almost. That means that all that’s necessary is to have the game in hand, the books that Jack Vance wrote about the world, to create a really compelling campaign environment. Using the creative base of the author, the GM’s own imagination cannot fail but to rise to the occasion. (Emphasis mine)

 

In my mind, I already own The Expanse RPG. My version uses a core mechanic that I feel is evocative of the setting (Cepheus Engine). I have the sourcebooks in the form of several TV seasons and multiple books and short stories. I don’t need somebody else’s vision that doesn’t strike me as evocative of the stories or setting.

The second RPG I nearly bought was another Kickstarter campaign. Tachyon Squadron from Evil Hat Productions is basically Battlestar Galactica with the serial numbers filed off rendered using the Fate Core system:

Tachyon Squadron is a Fate Core supplement that blends space opera and military sci-fi. It’s Evil Hat’s take on popular stories about interstellar battles, like the ones that have ships with wings named after letters and the one where robots chase the human race through space. If you’re interested in deep space dogfights, friendly—well, usually—rivalries with fellow pilots, and playing scrappy underdogs with the deck stacked against you, this game is for you.

The project funded with 1,401 backers pledging $25,295 against a $7,500 goal. Like The Expanse RPG Kickstarter, Evil Hat was very generous and offers a free download Quickstarter version. It is pretty much as I expected as Evil Hat has previously sold a smaller, similar setting found in Fate Worlds Volume One: Worlds on Fire. In Kriegszeppelin Valkyrie the PCs are pilots aboard a giant War Zeppelin taking on “a horde of WWI mechanical monstrosities.” For Tachyon Squadron I actually was more interested in Stretch Goal 7:

STRETCH GOAL 7 (UNLOCKS AT $26,000): The Battle of Britain: At $26,000, we’ll start work on The Battle of Britain, a 5,000 word electronic supplement that applies Tachyon Squadron’s dogfighting rules to a WWII squadron of Spitfire pilots defending Britain. This supplement will include plane stats and mechanics to help you take to the skies with the Allied forces.

Alas, this stretch goal didn’t unlock. My potential Pilot-in-Training pledge of $12 would not have made a big difference.

What really turned me off about Tachyon Squadron was the over-the-top SJW proselytizing. It is so in-your-face I think it overwhelms the game setting. Even if I am able to put the SJW part aside I see the the game offering me little new. The major rule of difference, dogfighting, is likely not far from that found in Kriegszeppelin Valkyrie which I already own. Much like The Expanse, I have a Battlestar Galactica RPG in the form of the officially licensed Battlestar Galactica Role Playing Game (Margaret Weis Productions, 2007). This game uses the CORTEX Classic system which I generally like (indeed, I am still awaiting my CORTEX Prime: A Multi-Genre Modular Roleplaying Game Kickstarter to deliver – only 3 months overdue…so far). If I want to do Battlestar Galactica using Fate Core I already own all the setting and rules material; why should I invest more money into a near-version that alleges to be ruleset but comes across more like a SJW propaganda tract?

Passing on The Expanse RPG (Green Ronin’s AGE System) and Tachyon Squadron (Evil Hat’s Fate Core System) got me thinking about the games and systems I do have. Last June I listed Star Wars The Edge of the Empire RPG (Fantasy Flight Games) as one of my Top 3 RPGs. I like the Narrative Dice System and want to play more with the RockyMountainNavy Boys. Thinking about expanding beyond Star Wars I picked up GENESYS: The Roleplaying Game for All Settings.

Genesys is a role playing system designed for flexibility and adaptability, specifically tooled to work with any setting imaginable. The Genesys Core Rulebook not only contains an overview of the rules and how the innovative narrative dice system works, but everything a GM and players need to run adventures in five completely different settings. Everything from equipment to adversaries, character abilities to an overview of narrative tropes, all is provided in the core rulebook for Genesys. With a system so adaptable and expansive you can explore every popular roleplaying genre, from classic fantasy style campaigns, to modern day detective thrillers, and even to a far off sci-fi future, Genesys doesn’t fit into any one genre of roleplaying, and instead invites players to craft their own stories with unparalleled freedom.

Taking GENESYS and combining it with Gary Gygax’s Dying Earth GM approach, I can likely make a version of The Expanse or Battlestar Galactica – or any other setting I chose to explore – for myself.

The most important RPG lesson I learned this month is that I don’t need Kickstarter to make an RPG for me that “isn’t quite right”; I just need good books and a good ruleset.

“You’re using Star Wars and physics in the same sentence….”

I had an unusual exchange on Twitter the other day. Unusual because I (frankly) was a bit of a jerk to @beltalowda_ and unusual because I let popular sci-fi get under my skin.

First, the exchange:

IMG_799365D945E9-1

I cut off my response because I was a bit of a jerk and talked down to @beltalowda_ (hey, if you’re reading this, sorry!).

The main point I was trying to make (on Twitter? I must be crazy!) is that science fiction and science fact don’t mix well, especially in the realm of gaming. Star Wars is nominally science fiction (I would argue it is more science fantasy but that is another, fruitless, discussion) and the games related to the franchise reflect that origin. Star Wars: X-Wing Miniatures Game today is ranked as the #63 game overall on BoardGameGeek as well as the #7 Customizable Game (interestingly, Star Wars: X-Wing Miniatures – The Force Awakens Core Set is ranked #4 in the Customizable Game category). These games use what gamers often refer to as “cinematic movement,” i.e. they fly about in space like airplanes. This is far different from what space combat will likely look like. Atomic Rockets, IMNSHO one of the best sites on the internet, devotes a whole section to Space War and what is closer to reality. For me, one of the hallmarks of a hard sci-fi game is the use of vector movement, ala (loosely) The Expanse.

Overall, The Expanse is better at hard sci-fi than many shows but even here there is a good deal of “handwavium” involved. Scott Manley on YouTube has made one of the better explanations so far:

My personal gaming experience has shown the same conflict between hard and popular sci-fi. I have bounced between hard (realistic?) sci-fi and more cinematic portrayals. Here is a list of a few games in my collection and how they looked at space combat:

Finding the right balance between popular sci-fi and hard sci-fi gaming is tricky. For myself, games like Star Fleet Battles and its derivatives are fun because of the theme since when playing these games I am choosing theme over mechanics. Some of the more hard sci-fi games are fun with a bit or realism thrown in (like Mayday) but some go too far (Squadron Strike: Traveller) where the fun has a hard time overcoming the difficulty of rules and play.

The upside of all this is that the gaming scene is broad enough that either preference, cinematic or vector, can be accommodated. It’s a matter of choice, and the game industry is healthy enough to give us that choice. Even if I am choosing not to play.

Random Gaming Thoughts (Good & Bad) on the First Weekend in May 2018

Sort of a hodgepodge post today. More a collection of random gaming (and beyond) thoughts than anything in particular.

Travel Gaming – Took along several solo games to play while on the road this week. Only got to play one – Merrill’s Marauders: Commandos in Burma 1943-1944 (Decision Games, 2016).

RPG Gaming – Gypsy Knight Games had their May the Fourth Sale going on so I picked up the new Manhunters: Bounty Hunters in the Clement Sector (2018). This has a very Classic Traveller RPG and Firefly-like vibe to it. I also picked up Uranium Fever: Asteroid Mining Rules for the Cepheus Engine (Stellagama Publishing, 2018). I really need to get back into RPGs. I am still awaiting my now-delayed Cortex Prime: A Multi-Genre Roleplaying Game by Cam Banks from Kickstarter. As much as I like Fantasy Flight Games Star Wars: Edge of the Empire RPG I probably should pick up the “generic” Genesys RPG.

Speaking of Star Wars – I hear that FFG is going to be publishing X-Wing Second Edition. This one will be app-enabled.

I think I’ll wait for Ares Games and their Battlestar Galactica version instead.

Speaking of Kickstarter – In April I backed No Motherland Without, a 2-player card game about North Korea since 1953. It really looked interesting. I had really high hopes. It was cancelled – for all the right reasons I am sure. I hope they come back and try again, maybe with a stronger publicity campaign. Personally I watched The Players Aid review and was sold:

Veterans in The Expanse (very mild spoilers for S3E4) – I like The Expanse TV series but one line got me going last week. Alex states he has done his time and is an honorably discharged veteran. His implication is that he is special. As an honorably discharged veteran myself I resent this attitude. Unfortunately, I see it everyday – too many veterans who believe that since they served they have a special privilege above “mere” civilians. They grouse when a place does not offer a veterans discount or the like. Being a veteran does not make you a special citizen. This is not the world of Robert Heinlein’s Starship Troopers (the book, not the horrible movie) where only veterans are citizens. Veterans get many privileges; be humble not an entitlement baby!

Narrowing #TheExpanseBoardGame – or – Expecting too much from theme

IMG_2055My first impressions of The Expanse Board Game (WizKids, 2017) were less-than-favorable. In the few weeks since I have been able to sit back and reappraise my feelings towards the game. I now see that I focused too much on theme and not enough on game play. If I remove many of my feelings about the theme, the game that emerges is a good influence-placement game using the theme of the The Expanse TV series.

I will be the first to admit I am not a hardcore fanboy of The Expanse, but I do like the TV series (Seasons 1 & 2) and have enjoyed the first few books. I came to the franchise backwards, seeing the TV series before I started reading the books. In several ways my perception of theme is colored by the TV series. The Expanse Board Game draws almost exclusively from the TV series, so in my first impressions I inevitably compared the two. In my first impressions I didn’t like the game because I kept trying to see the game as a replay (or version of) the TV series. The Expanse Board Game, though based on the TV series, is actually a very different look at the franchise. I should have paid more attention to the front matter in the rule book:

The Expanse is a game of politics, conquest, and intrigue for two to four players. Players spread their influence through the solar system onto important Bases using characters and events in the Expanse Universe, and must make clever use of their special faction abilities to gain an edge.

But even this summary is a bit misleading as I believe there is little “politics,” no real “conquest,” and very limited “intrigue” in the game. What The Expanse Board Game does deliver is a (sorta) asymmetrical influence-placement game based on The Expanse Universe.

Politics – When I see a political game I expect negotiation or a focus on indirect warfare (the Diplomatic, Intelligence, or Economic factors). The Expanse Board Game has no real negotiation element, a bare nod to diplomatic (i.e. the UN Diplomat cubes) and only a limited nod to economic (each factions key resources).

Conquest – Unless one conflates the definitions of conquest and influence there is no real conquest in The Expanse Board Game. Even when there is “confrontation” the result is limited to removal of fleets or influence cubes. Sure, fleets must be rebuilt but the relatively non-violent nature of the confrontation does not make it feel like a conquest to me.

Intrigue – Intrigue to me comes across as some form of secret plans or the like. Certainly, there is an element of secrecy in The Expanse Board Game but even that element is minimized as the game has almost no hidden information. Indeed, the game is mostly open information with cards on the Action Track visible to all and Kept Events remaining face-up in front of the players.

Asymmetrical Abilities – What The Expanse Board Game does well is using theme in the asymmetric abilities of the factions. From the UN being able to use superior planning to take the second card on the Action Track at no cost to the Martian battleships and the like, the use of theme to differentiate the factions is the most successful part of the game. This trend continues to a degree in the Faction Special Tech Cards that enter after different scoring rounds. These special abilities all are keyed to the placement – or
removal – of influence.

Influence – What The Expanse Board Game comes down to is influence. The game
is actually very simple; have the most influence at the right time for Scoring. Influence has two elements – orbital control and bases. Given the somewhat secret element of Bonus Sector selection, the players are challenged to have the right influence at the right times in the game. Players may find they need to “shift” influence around during the game as they try to guess (or manipulate) where the next Bonus Sector will be scored.

Rocinante – The Rocinante was actually the part of the theme I had the most trouble wrapping my head around. In the TV series the Rocinante and crew are the focus; the narrative element through which the story is told. In The Expanse Board Game the Rocinante has a far different role. With control of Rocinante going to the faction with the lowest Control Points, the ship becomes more of a pawn than a true protagonist. It is a bit disconcerting (disconnected from theme?) to see the ship only be used as a fleet (albeit one that can’t be removed) with special abilities that only come into play during Scoring. The special abilities also still very limited. Of the four, I actually find the Amos Burton ability the most powerful (“Remove 1 opposing fleet in the Rocinante Orbital for each friendly fleet there (including the Rocinante)”) which, to me, again doesn’t quite square with the TV Series where James Holden (special ability – “Place 1 influence anywhere”) comes across as the central character. I also have a bit of thematic dissonance when the Rocinante is controlled by the Protogen faction. So great is this dissonance that I have to rationalize the situation by telling myself that the Rocinante was not really being “controlled” by Protogen but more properly is being “manipulated” by the corporation.

Reappraising The Expanse Board Game

By reducing my expectations of theme, my respect for The Expanse Board Game has actually grown. The game is about placing influence – and little else. It uses the theme of The Expanse Universe to derive the asymmetric abilities of the factions. The Rocinante – a ship and crew with a key role in the TV series and books – has a lesser role in this game. In the end, The Expanse Board Game delivers what it promises – an Expanse-themed influence-placement game playable in around 60 minutes.

#FirstImpressions #TheExpanseBoardGame (WizKids, 2017)

From the publisher’s blurb:

The Expanse, a board game based on the Syfy television series of the same name, focuses on politics, conquest and intrigue similar to the board game Twilight Struggle, although with a shorter playing time. The card-driven game uses key images from the show, along with action points and events that allow players to move and place “Fleets” and “Influence”. (BGG)

It is not often that a publisher’s blurb captures a game so completely as WizKids has done for The Expanse Board Game (TEBG). After purchasing the game and playing it a bit, I am torn in my feelings for the game. To me, TEBG feels very much like a “classic” Eurogame – in a negative connotation of the definition; great mechanics with a pasted on theme.

The BoardGameGeek Wiki defines Eurogames as follows:

“Eurogames (or alternatively, Designer Board Games or German-Style Board Games) are a classification of board games that are very popular on Board Game Geek (BGG). Though not all eurogames are European and not all of them are board games, they share a set of similar characteristics. A game need not fit ALL the criteria to be considered a Eurogame.

Most Eurogames share the following elements:

  • Player conflict is indirect and usually involves competition over resources or points. Combat is extremely rare.
  • Players are never eliminated from the game (All players are still playing when the game ends.)
  • There is very little randomness or luck. Randomness that is there is mitigated by having the player decide what to do after a random event happens rather than before. Dice are rare, but not unheard of, in a Euro.
  • The Designer of the game is listed on the game’s box cover. Though this is not particular to Euros, the Eurogame movement seems to have started this trend. This is why some gamers and designers call this genre of games Designer Games.
  • Much attention is paid to the artwork and components. Plastic and metal are rare, more often pieces are made of wood.
  • Eurogames have a definite theme, however, the theme most often has very little to do with the gameplay. The focus instead is on the mechanics; for example, a game about space may play the same as a game about ancient Rome.”

TEBG hits all of these points, but with mixed results.

TEBG does a good job of capturing the feel (theme) of The Expanse TV series. Using Eurogame mechanics the players place influence (tracked using small wooden cubes) on various bases throughout the Solar System. To place influence usually requires a fleet in the orbital above the base. Although the game mechanics are simple, each player/faction has unique asymmetric abilities which allow them to “break the rules” in thematically appropriate ways. For instance, while is usually cost 1 Control Point (CP) to take the second action card, the United Nations (UN) player has Planning as their initial Technology which means the first two action card slots cost 0 CP. As the game progresses, more thematically-appropriate technologies are gained by each faction.

“Combat” in TEBG consists of removing influence or fleets (which can be rebuilt). This is not a cooperative game; ruthlessly building your influence while reducing your opponents is the real core mechanic.

TEBG uses much artwork from The Expanse TV Series. Although this makes the game appear like The Expanse, some of the artwork does not have a clear connection to gameplay. For instance, the action card Scopuli can be used for 2 Action Points or as an Event by the Martian Congressional Republic (MCR) or UN. The Event states, “Place 1 influence on each Saturn Base where you do not have influence.” I do not see how this is related to the Scopuli in the TV series which is [SPOILER ALERT]:

…a Martian light transport freighter from Eros that was in service to the OPA. One of its crew was Julie Mao and it was attacked by the Stealth Ship Anubis. It was later used as a lure in the ambush and destruction of the Canterbury.

To me this is a thematic disconnect. I think Scopuli should be used as an Event to the advantage of the Outer Planets Alliance (OPA) or ProtoGen. Granted, most of the action cards have a picture that ties well to the event described, but I think to make the connection one must be a real fanboy. If a player is not knowledgeable of The Expanse the immersion into the game will not be served by the graphics.

The full impact of all these design and graphics decisions is an area control game that looks like The Expanse. The game comes across as very functional; simple game mechanics with some asymmetric differences in a kinda staid, plain package.

Finally, I have an issue with the component quality in TEBG. The board uses a non-glossy finish that, while good for pictures, has already shown rubs and scratches after just two plays. I also have a major problem with the Quick Start Rules which use white text on a semi-transparent background over a starscape page. The font, smaller than that used in the main rule book and the third layer of printing has lost all its edges and is nearly impossible to read.

It is going to be interesting when The Expanse Board Game lands on the Family Game Night table. All of the RockyMountainNavy Boys know a bit about The Expanse, but none are fanboys, Thus, the success of this game will stand not on theme alone (which appears to be much of the buzz around the game) but on its ability to blend graphics and gameplay into a enjoyable gaming experience.

 

#RPGThursday – Ship Files: Atticus Class Freelancer (Moon Toad Publishing, 2017)

Ship Files: Atticus Class Freelancer, Written by Ian Stead, All Artwork and Layout Ian Stead, Compatible with the 2d6 SCIFI OGL and The Cepheus Engine SRD, Copyright © 2017 Moon Toad Publishing.

Atticus is my first Moon Toad Publishing (MTP) Ship Files book. I am a fan of Ian Stead (@biomassart on Twitter) and greatly enjoy his work for Gypsy Knight Games and their Alternate Traveller Universe/Cepheus Engine Setting Ships of the Clement Sector. I had seen several other MTP products but it was not until very recently that I made the connection between MTP and Ian.

Atticus is a 100 dTon fast (Jump-2 / 6G acceleration) multi-use vessel  – a perfect ship for a small group adventure in a small-ship universe setting. But what really sets the Atticus apart from the usual slew of Traveller/Cepheus Engine ships is the fact it is a tail-sitter! This makes Atticus a design closer to hard scifi than the usual “airplane in space” found in so much space opera. It also harkens back to classic Traveller RPG designs such as Broadsword or Azhanti High Lightning where the decks were stacked. In some ways I have to wonder if Atticus is Ian Stead’s version of Rochinante from the TV series The Expanse. Regardless, Atticus is an interesting design that can be dropped into any Cepheus Engine adventure from space opera to hard scifi.

The Ship Files book is a 24-page full color pdf. The file book starts with an in-universe description of the Atticus that right up front addresses the unusual configuration. This part is not to be skipped for there are many little details that a referee (or player) could use as adventure seeds. Statistics using Cepheus Engine are provided, as well as many line and color drawings and deck plans. Actually, there are two variants presented; the standard and a non-jump version. An example crew is also provided; three instead of the usual four members because, “it is currently one person down, the crewman having left over an argument about pay” (p. 16) Speak about an adventure seed!

MTP Ship Files books also include a two-page Spacecraft Record sheet. This sheet lays out the ship statistics in a much easier to understand manner than the simple table usually presented in Cepheus Engine.

I was very pleased to see that Ian took advantage of several Cepheus Engine products beyond the basic System Reference Document in creating this ship. Ian used the spectacular Anderson and Felix Guide to Naval Architecture (2E) published by Gypsy Knight Games as well as the recently released Cepheus Engine Vehicle Design System. I am very glad to see third-party publishers taking advantage of each other’s products; it builds community and gives us customers a better product!

Ship Files: Atticus is not without its flaws. Page numbering is laid out as in a book but the pdf file is sequential meaning page “2” of the pdf shows “1” at the bottom. This makes the table of contents one page off from the search function. The first Spacecraft Record sheet shows the class name as “Polixenes” which I take was a previous Ship Files product. Neither of these flaws are egregious nor in any way degrade the overall superior quality of the product. This product is also a real steal at $3.99 on DriveThruRPG.

Recommendation: MUST BUY!

 

#TheExpanse Ships in #TravellerRPG

Watching “Home” (The Expanse, Season 2, Episode 5) with the Rocinante at high-g burns got me back to thinking about the ships of The Expanse and how they could be portrayed in tabletop RPGs. I previously looked at the Epstein Drive and how it might be translated into game terms for use in Traveller RPG or Cepheus Engine or Orbital 2100.

**WARNING – Minor Spoilers Ahead**

Going all the way back to the first book in the series, Leviathan Wakes, the small shuttle Knight gives us some insight into the technology of The Expanse:

It wasn’t long before Alex called down, “Okay, Boss. It’ll be about a four-hour trip flying’ teakettle. Total mass use at about thirty percent, but we’ve got a full tank. Total mission time: eleven hours.”

“Copy that. Thanks, Alex,” Holden said.

Flying teakettle was naval slang for flying on the maneuvering thrusters that used superheated steam for reaction mass. The Knight‘s fusion torch would be dangerous to use this close to the Canterbury and wasteful on such a short trip. Torches were pre-Epstein fusion drives and far less efficient. (Leviathan Wakes, Chapter 3)

From the book we know that the trip covers 50,000km. Working with classic space travel time equations, we can compute the Knight is traveling at about 1.0368 m/s or just over .1G acceleration.

Later in Chapter 5 we see the Knight running flat-out at 2G acceleration. At this speed the same 50,000 km trip should take only 53 minutes, which is a bit shorter than the approximately 70 minutes obliquily stated in the book. At this point it is unclear if the 2G speed is the upper limit of the teakettle or the fusion torch at low power.

The Knight does eventually clearly light it’s torch:

“Roger that, XO. Bleeding-g burn-and-flip laid in. Angled approach course so our torch won’t burn a hole in the Cant. Time to rock and roll?” Alex replied. (Leviathan Wakes, Chapter 5)

Here we have to interpolate the fusion torch acceleration based on Holden and his apparent weight. When lighting the torch Holden weighs 500 kilos. Assuming he is an average 75 kg to begin with, this works out to almost 7G. Interestingly, from the novella The Drive we know that 7G is the instrument limit on Solomon Epstein’s ship that he installed his new drive on, indicating that the fusion torch may have an upper limit of 7G.

In summary, we can say the shuttle Knight has maneuvering thrusters (teakettle) that operate efficiently at .1G. The shuttle also has a fusion drive (torch) that can accelerate it at up to 7G.

The Knight‘s torch drive could deliver a lot of thrust, but at the cost of a prodigious rule-burn rate. But if they could save the Cant, it wouldn’t matter. (Leviathan Wakes, Chapter 5)

The missiles that are fired at the Canterbury are also very impressive:

As if in answer, six new objects appeared on his radar, glowing yellow icons appearing and immediately shifting to orange as the system marked their acceleration. On the Canterbury, Becca yelled out, “Fast movers! We have six new high-speed contacts on a collision course!”

“Jesus H. Christ on a pogo stick, did that ship just fire a spread of torpedoes at us?” McDowell said. “They’re trying to slap us down?”

“Yes, sir,” Becca said.

“Time to contact.”

“Just under eight minutes, sir,” she replied. (Leviathan Wakes, Chapter 5)

For these six missiles to cover 200,000km in 8 minutes means their acceleration has to be around 150G!

In Leviathan Wakes, Chapter 51, Holden tries to remember how fast the Roci can go:

He tried to remember the Roci‘s maximum theoretical acceleration. Alex had already flown it at twelve g briefly when they’d left the Donnager. The actual limit was one of those trivial numbers, a way to brag about something your ship would never really do. Fifteen g, was it? Twenty? (Leviathan Wakes, Chapter 51)

In the episode “Home” if I caught the screen correctly it looks like the Roci was accelerating just over 17g. This again is in line with the book; and way faster than the 6g of Classic Traveller or Cepheus Engine and far ahead of the technology in Orbital 2100 where the alternative Nuclear Pulse Fusion Drive tops out at 1.2g! Compared to the Traveller RPG or Cepheus Engine universe, the ships and weapons of The Expanse are way faster and likely far more deadly too.

As late to the game as I am, I look forward to reading more of The Expanse series and seeing what further ship secrets are hidden within.


PS: The math for figuring time and acceleration is actually easy, but to help there is an EXCELLENT site at http://www.transhuman.talktalk.net/iw/TravTime.htm that does the math for you!
