Coriolis Wednesdays

Coriolis Wednesdays
Extremely Initial Impressions

Okay! My week of endless awesome gaming has finally come to an end with Coriolis last night. Regular Tuesday crew plus very special guest star Ralph Mazza!

The experience was all over the place and I don’t want to put too much weight on anything since I’m coming off a week of near total exhaustion. Tl;dr it was fun-ish and I might need to do some homework to fix some possible deal breakers.

The Essential Economic Cycle

The big takeaway, I think, has to do with the essential engagement cycle of the game. That is: make a roll, engage the prayer mechanism, pay the GM a darkness point, deal with the GM’s bullshit, repeat. It’s been modified from the very excellent semi-rich dice of Mutant: Year Zero and I have to think it’s because the designers didn’t actually understand or appreciate why MYZ works. It’s been simplified for Coriolis and maybe broken in the process.

In MYZ, a single 6 is a success no matter what, and you have the option to “push” once and reroll all your misses. If you do, you might get more 6es (yay!) but you’re gambling against getting 1s, which are damage you need to deal with. Depending on which of the three die colors they show up on, that’s different flavors of bad: broken gear or mutation flareups or whatever. It’s a neat choice and more importantly it feels like a choice.

In Coriolis, a single 6 is a “limited success” and 3 or more 6es are a “critical success.” I kind of read between the lines and actually made this slightly gentler by making 2 successes an unadored just-plain-old success, treating a single 6 as the only “limited success” and applying complications. This is already 90% supported by RAW if you look at how the skills are written. So my small tweak in no way changes the basics. Anyway. Instead of “pushing” there’s “praying,” which lets you reroll all the misses and gives the gm a Darkness Point (DP).

Given the die pool sizes, it’s awfully hard just to get a single 6 much less multiples. So either you’re fucking up an awful lot or you’re praying a lot.

There were a few thoughts on this from the players.

One is that if you’re praying all the time, it’s not really a special thing or even a choice any more. I think that’s accurate! But I think it’s also an aesthetic call. Like, maybe praying all the time is expected and the GM is supposed to have a really healthy supply of DPs. It’s not meant to be a juicy choice like it is in MYZ.

That leads to the point of darkness points.

In Coriolis, there’s a lot of stuff the GM is specifically constrained from doing, both mechanically and narratively, because they have to buy those moves with Darkness Points. In some cases it’s tactical stuff: my NPCs can’t take reaction moves like parrying or opportunity attacks. There’s even nastier stuff on the narrative side: I can invoke a character’s Problem as I see fit for a DP. I can inflict various maladies. I can complicate scenes with a list of stuff that, as I read it, I’m not allowed to without DPs.

That would normally be a really interesting twist to me! And that’s how I read it initially: if the players don’t feed me DPs and just accept failure consequences (or limited success complications), there’s a whole menu of problems that I cannot inflict on them. But I was playing with Ralph Mazza, an implacable system-destroying terminator from the future, who pointed out that the players don’t actually have that much power to starve the GM because there are other ways to generate DPs than prayer: Traveling deep into space, and being exposed to horrible shit. As the GM, I can engineer the situation such that I’m still getting DPs — not as many, perhaps, as when the players are also freely praying and don’t give a fuck. So I don’t think that’s the whole story.

There is a whole lot more DP flow in combat scenes though, since the stakes are so high. Probably it still breaks close to even: each time a player needs a few more 6es to generate a crit or whatever, they pray and I immediately spend on reloading or reacting or doing all the other PC-only stuff I have to pay for.

It feels, at a very high level, like the economy is not quite dialed right. But I’m not sure! I’d like to see another session or two where the players are maybe stingier with the prayer and figure out what they’re doing narratively to generate DPs anyway. Stuff like facing horrors and flying deep into space, both of which are, you know, the things they signed up to do. I’m not sure if it’s an actual perverse incentive or just a hard choice to face: doing their job inherently attracts the attention of Darkness.

Space Travel RAW Is Fucked Up

My absolute favorite thing about MYZ is how the Zone spools out. The PCs head out into the Zone, I randomly generate and draw and otherwise engage in procedures, and the world grows in an interesting, organic way. It’s a sandbox that the players give a shit about, and that’s a dime-sized design target they’ve hit.

It looked like the travel stuff in the Atlas Compendium was going to try and achieve that vibe. You decide what kind of space they’re traveling in, roll on some encounter tables, roll again to see how the NPCs feel about you (friendly, angry, whatever) and, you know, just kind of procedurally work your way through a journey.

Well so the cool thing in MYZ’s zone generator was that you might not actually encounter anyone, or it might be a weird phenomenon. There were several axes around which you’d generate your square mile blocks. In Coriolis, though, you roll for an encounter every two hours if you’re in heavily traveled space. EVERY TWO HOURS. It takes about a day per AU to travel, as far as I can tell (it’s super iffy). Am I really rolling 12 times a day? Really? And the various tables are way chock full of ships and people. If I’d actually done that, it’d be an endless circus of crap. Not a good look.

I’m gonna need to fiddle with that system because as written, it’s not interesting at all. The travel tables need to make encounters more meaningful, I think.

There’s also an undiscussed thing in the system where it seems like space travel is supposed to be a meaningful, interesting choice BUT it might also be that space travel is kind of skipped over ’til you either get to your destination or get into a space battle. There’s system support for both, which I felt like kind of didn’t do either one very well. I much preferred the feeling of making the trip its own set of situations and problems. The DP system supports that as well, giving me opportunities to introduce technical or supernatural problems along the way if I have the budget for it. Or, one assumes, being forced to leave the PCs alone if I don’t. But again, I can kind of fiat my way into getting at least a few DPs because of the depth or length of the trip.

Adjunct issue: it feels like money and upkeep is supposed to be a driving motivator for the PCs, but there’s not a whole lot of support for that. There’s an interesting table that describes upkeep costs that vary depending on where you perform your maintenance (more civilized = cheaper, which is good!). But there’s also a thing where portal travel is so fucking terrifying that you’ll most likely split the navigation costs with a caravan of ships. That’s a great image, very desert trader caravan-feeling, but then there’s nothing procedural to tell you how big or how often a caravan might be, particularly headed somewhere obscure. It’s fine, no big, I can totally just eyeball that. I just wish they’d made a bigger deal out of it because I think it would have been interesting.

My gut tells me they tried to make it interesting by introducing caravans and bulk haulers (like, you’d literally just get hauled through the portal) into possible space encounters. You know, the one you roll for every 2 hours. Dumb, boring, I think we can do better.

Weird Holdover System Problems

Coriolis has exactly the same system problem as everything else Free League has done: they never, ever consider the rules in light of the players using them against each other. The PvP stuff just falls apart and it’s an awful mess.

The game introduces a system called Reputation, which produces relative bonuses and penalties between characters. I think it’s straight out of Mutant Genlab Alpha, which has an identical system. If you’ve got more rep than your target, you get bonus dice equal to the difference. If you’ve got less, you LOSE dice equal to the difference. That is a two-die delta per difference in a roll-off that’s intended to be a versus test.

We had a situation where the rich scientist ship owner character (Rep 7) needed to order the plebian humanite pilot (Rep 1) into cabin confinement. Under RAW, the captain got +6 dice and the pilot got – 6 dice. That is ridiculous. I think I’m gonna have to just give the higher-rep person the bonus and call it good. I’m totally fine with rep being a heavy mechanism but a 12 die difference means you might as well not even roll.

There’s some math-lazy shit in combat as well (had to have a fight to see how it worked!) that bugs me but I don’t think breaks the game. It might. The most egregious is deciding whether to aim a shot or open up with full auto. Aiming gives you bonus dice, and given the extreme likeliness of prayer, you’re gonna get a good outcome with a big pool and a single reroll. Automatic fire lets you reroll all you want without praying (cool) and if at any point you rolled a 1 your clip is empty and you need to reload (also cool). But it costs you 2 dice. And obviously, the bigger the pool the more likely you’ll empty your clip even on the very first roll. That seems like a terrible choice.

That stuff doesn’t even bug me. We’ll just fine tune it until we get where it feels like a better choice.

Last Thoughts

The vibe is marvelous. It’s also highly stylized, to the point where it’s pretty dissonant, I think, for the players to live in a world where everyone wears caftans but also modern spacesuits.

It might turn out that the game really does want everyone praying all the time, but then I think it becomes very hard for the players to meaningfully push against that to keep the darkness from creeping into their lives. I’m interested to see if the players will start pushing against rerolls in the hopes of keeping my DP budget lower. It might also be that if they knew what I can’t do without DPs, they’ll face a more educated decision.

I miss MYZ’s richer dice. Coriolis feels…impoverished. Might in fact fiddle a bit and see if maybe I can reintroduce more of that vibe, like 1s are DPs I earn but only if you pray, more MYZ style. Hell, maybe go full MYZ: 1s on the attribute dice are DPs, 1s on the skill dice are yes-but complications, 1s on the gear dice break the gear. (Oh shit Ralph I think I fixed it!)

Oh Yeah Storytime

Our group is an explorer crew, with a trailblazer, scientist and engineer as PCs and a soldier and computer/sensors nerd as NPCs (played last night by Ralph, who came up with such an awesome backstory OMG I can’t even).

They got hired by the Foundation’s archaeological institute to go check out a wreck they’d acquired in a distant system. The wreck was of a cruiser from the Portal Wars era, like 600 years old, that had gone missing and just decided to show up.

Some marvelous competency porn scenes (thank you so much for that turn of phrase Jonathan Perrine ) en route. By the time they started their big slog waaaay out to the gas giant zone I’d accumulated a very tasty DP pool, which I then used to start dicking with the crew: bad sensor array, weird spooky signals from a nearby black hole, then aw dang their ship’s quirk — faulty thrusters — meant the ship entered an uncontrolled tumble for a while. The ship’s engineer fucking hates space and spent lots of time barfing. The trailblazer occasionally gets possessed by … things … when he’s out in the dark so that’s amusing. The scientist is a drunk. The soldier wants to shoot people when they barf or act crazy or drink too much so, you know.

Then haunted ship hijinks ensued, concluding with a freaky ass twisted column of ancient crew bodies gathered in the ship’s caverous bridge, and then a fight with a strange humanoid made of nanites, maybe.

I was reminded of how much better this kind of game is when I have time to prep. Thanks to New Mexicon all last week I’d had like an hour to doodle down and immediately forget a bunch of ideas.

Continuing next week! Bring a snack because I’ll probably write too much again. 😉

  1. 1. That “limited” or “critical” but no “normal” success thing bugged me when I first saw it and still bugs me now that you reminded of it.

    2. I’m really surprised that the random encounter system doesn’t employ the DP economy at all. I mean, why have encounters be different from any other GM move?

    3. Do you feel like you needed to do this much hacking with MY0?

  2. Mark Delsing

    I’m fixing 1. Totally trying the dice thing next session.

    2. That is a SUPER GOOD CALL. Love it. I’ll figure it out.

    3. That’s a great question because it might have! I remember struggling with PvP stuff in particular. In retrospect I feel like it was mostly RAW but if I went back to my posts I’ll bet there were tons of tweaks. Like, I remember fiddling with Zone encounters because they’d forgotten to tell you exactly what multiple 6es meant on those rolls.

  3. Coriolis is also a nostalgia project for Free League. I was originally released by another Swedish RPG developer in the early aughts. That earlier RPG is where Free League got their name. Some of their choices I think may come down to being a homage to that earlier game. They saw holes they wanted to fill but also were okay with the basic gameplay.

    The space encounter every two hours is suppose to be in heavily trafficed areas, like Coriolis itself or the portals near the center of the system. This kind of makes sense because travelling from Coriolis to Kua is less than a day trip. In deeper space the game suggests once per week or once per day. In either case I missed the tactile sense of zones from MY:0. There was something nice about rolling something up marking the map and maybe there beings some npcs and then I would scribble notes about what that group is up to.

    A solution I think would be to simplify the encounter into a traffic jam. That there are a bunch of different vessels and how does that play out? but that still doesn’t flesh out a sector of space as I would like.

    The idea that I couldn’t touch certain knobs or levers without DPs was one of the things that gave me trouble running the game.

  4. Paul Beakley Sorry – comments popped in between what I read and what I was replying to. It was Mark Delsing’s second point – that you can tie encounters to DP. I was trying to remember if you gained DP for time in space – if so, it might make sense to just do away with random encounters and always spend DP for encounters? I dunno, just riffing based on my memory of the game.

  5. Going full MY0 dice would be easy. I ranted about it somewhere and got push back and so wrote it up and said…”like this”.

    I passed my “don’t tell Paul how to run his game at his own table” save…mostly…

  6. The madness with the number of encounter rolls stood out to me as just as crazy as in The One Ring RPG. “Are you telling me, that the four of us are going to have to roll four times each? Per day? For five days? Why don’t you just dish out 1d3 Encounters and some fatigue and/or Shadow points and spare us the idiocy of pointless rolling for 20 minutes?” There simply has to be a better way to solve these things.

  7. Ulf Bengtsson we talked quite a bit about comparing Coriolis travel to The One Ring travel. We had no problem at all with TOR, everyone totally bought in, and I’m not sure why tbh. Maybe it’s because individually we’re making the rolls and tracking the outcomes? Maybe because stuff like fatigue and madness was kind of variable between characters? The DP economy in Coriolis feels way different than that, unfortunately. I think I would have preferred that.

    I do feel like it’s a dialable, polishable procedure though, that I can come up with something that’ll work, be interesting, and present a real threat/challenge/opportunity.

  8. Paul Beakley We hated that part of TOR. Repeating the same die-roll over and over again was boring, pointless and borderline insulting. If you roll a die once it can be exciting to see if you get a six. If you roll it 20 times you can almost guarantee the six will come up and the whole thing is just a waste of time. I want the shortcut here. Less boredom. More action.

  9. Ulf Bengtsson interesting. That’s quite different from my experience. The travel rolls really served their purpose for us. Which was: keep reminding players they are not big damn heroes riding for glory, no one has fun hoofing it across half a continent; grinding them down so they were already part way to beaten when Big Deals happened, making the decision to engage or run meaningful, and to provide opportunities to seed flavorful bits in between big set pieces — moments of danger or travelogue items.

    In the end, rather than travel being just a generic way of fast forwarding between action scenes, the travel rules made the action scenes just periodic bits of danger between the real adventure of travel. Which felt very Tolkien.

  10. Hi! Great write up, reflections and critique. I’ve run a couple of sessions of Coriolis and got much the same problems, and the strange thing is that this post is the first real, structured and thoughtful critique I’ve come across on the game. I threw out or tried to hack some of the mechanics almost straight away when we began the first session, like the rules for reputation in manipulation rolls and the somewhat iffy space travel times/encounter rules.

    I’m VERY interested in the solutions you (and Ralph Mazza) come up with to the ”core problem”: DPs and praying!

    Your MYZ hack with different effects on different dice that come up on 1s seems cool! However, maybe such frequent gear problems may feel more at home in an apocalyptic game than in coriolis? Or wait, maybe it wouldn’t be so frequent after all. Also, if complications are mapped to rolled 1s on skill dice (which seems cool!), should one do away with the RAW rule that complications happens on a limited success?

  11. L. D. yeah, I would do away with the “limited success” thing and move complications to the skill dice. I think it’s 100% reasonable to have an outcome of “success with a DP and a complication.” I’m also intrigued by the additional decision before prayer, you know, looking at the 1s you’ve already rolled but aren’t suffering: can I handle giving away a DP? Am I okay with a complication?

  12. I haven’t played it, but I feel like, in response to L. D.’s comments about frequently-broken gear, that might actually be appropriate for the established setting. Ships that are held together by prayers and space-duct-tape fit both the rough-and-tumble sci-fi and the “1001 Nights” seat-of-the-pants adventure motifs.

  13. Adam D yeah, on that note: I might build durability into the tech level of the gear as well. There’s already a primitive/ordinary/advanced thing going on. That might also be 1/2/3 breaks the thing can take before it needs to be repaired? Or go backwards, yeah? That fancy-pants advanced computer can only take 1 gear break, but your chunky metal sword can take a beating!

  14. There are also other cool things that can be done with 1s on gear besides breaking.

    Ammo, collateral damage, injuring the mechanic, triggering a complication like a radiation leak or low fuel. Basically treat 1s like PBTA 7-9s with the harshness of the “but” tied to the number of 1s.

    I would do all the dice like this with gear vs ability dice differing only in the flavor of the “but”.

    In MZ0 Skill dice are free of complicating 1s, bit that’s an easy switch to flip. Maybe 1s on skill dice represent how much you need to than the icons for their blessings, representing a certain amount of prayer / sacrifice / devotion that must be met. If not met, prayers stop working…or something like that.

  15. One of the things I did when I ran Coriolis to address the successes thing, was revert back to MY0 and make any 6 rolled a basic success and then additional 6’s rolled could be spent adding scope or asking relevant questions. That helped and cut down on the number of prayers needed. Then if I wanted success with a complication I would just spend Darkness to add that.

    And ugh, the economy of Bir is what ultimately killed the game for me. The game does want you to spend to maintain the ship, to supply it, to pay of your debt on in each year, to pay for portal travel, to pay to carry weapons on station, and so on. But it also never really establishes how much a crew should be charging to do these missions. Before the game kinda died I was pretty close to abstracting bir into a BW like Resources stat with Cash dice or something.

  16. Colin J we’re dialing all that in right now too. I’ve just about got it figured out.

    (There’s also the 1/9th tithe if your characters are fulfilling their religious obligations.)

  17. Yeah, Coriolis feels like a good idea not quite baked. I have some issues with the setting as well, a bit too “Firefly but Arabic” and not much depth of drawing cultural trends from 1001 Nights and early arabic society (not to mention narrative structures). For those who speak French there’s a really interesting thread about orientalizing Coriolis on a french forum here: – Orientaliser Coriolis – CasusNO
