The Corridor

A science-fiction setting. This version assumes no familiarity with the Classic Traveller role-playing game whose rules the numbers come from; a companion document exists with the full technical derivations for those who want them. The Premise Two rich, technologically advanced worlds sit about twenty light-years apart. Between

Does My Bot Sound American to You?

Hooray for machine translation, although I’m sure quite a bit gets lost along the way. Which, conveniently, is exactly the blind spot that got me thinking about this in the first place. A Finnish communications professional, Maria Morri, recently posted about her experiences writing and thinking with different AI

Team Bravo: Designer's Notes

Or: how a question about a 1977 combat results table turned into a tiny game about giant robots. We wondered how settled the d6 outcomes were in wargames. Strength versus defense, roll a die, look up a table, repeat. Reasonable question. Charles Roberts worked it out in the late fifties,

The Intelligence Layer Needs a Signature Line

A companion piece, written in agreement with the enterprise intelligence layer argument — and in service of the parts it leaves for the reader to supply. The intelligence layer argument is generally right about the thing most organizations get wrong. Governance debates stall because they're abstract, and infrastructure makes

Team Bravo: Combined Arms

A 24” x 24" table. Six-sided dice. A tape measure. Any models you like. UNITS have five numbers, printed on a card and never modified by anything: Skill (2–5), Move (inches), Resistance (0+), Hits, Size (1–5). Plus weapons, each with a Power and a Range in

The Floor and the Room

There is a paragraph making the rounds among people who write about music, and it has done the useful thing of splitting a room that mostly agrees with itself. It appears near the end of an essay occasioned by yet another round of publication closures, and it proposes that we

The Book of the Distance: Stay As You Are

A solo journaling game of one crossing. You need: this document, a standard deck of playing cards, and a journal. The journal is the artifact. Everything else is scaffolding. The shape: twelve sessions in three stages — Departure (1–4), Transit (5–8), Arrival (9–12). A session takes thirty minutes

The Shape of the Questions

Six years on, the pandemic is being discussed constantly. That is worth noting at the outset, because the more common complaint — that nobody wants to talk about it — is not quite accurate. Hearings are held. Documents are subpoenaed. Retrospectives are published on anniversaries. Podcasts relitigate school closures in detail. The

Kestrel-class Short-Haul Transporter

Designed under Classic Traveller Book 2 (1981) rules. Paragraph Description Using a custom 1,000-ton hull, the Kestrel-class short-haul transporter is a streamlined, cargo-first jump-1 merchant built to move as much freight as possible between neighboring systems one parsec apart. Its commercial purpose is deliberately

The Twenty-Ninth Expedition

Mörk Borg in a corner of the Hereafter Needs: Mörk Borg. Cloud Empress and Land of Cicadas for the world, the spells, the crests, and the hexes. Not the Panic Engine. The Position Twenty-eight Cloudling expeditions have gone down into the Lowland Wastes to take it for the clouds.
