The One-Page Session Zero That Actually Survives Week Three

Most session zero docs get written once, nodded at, and buried in a Discord channel by the third session. Here's a leaner format — and a better place to keep it — so it actually gets used.

Every GM I know has written a session zero doc. Tone, content lines, house rules on who has final say on rulings — the usual checklist. And every GM I know has watched that doc get read once, nodded at, and then quietly buried under three weeks of session recaps in a Discord channel nobody scrolls back through.

The doc isn't the problem. It's that most session zero docs are written as a one-time compliance exercise instead of a living reference, and they get stored somewhere nobody revisits.

Why the standard version dies

A typical session zero doc runs two or three pages: safety tools, campaign pitch, character creation rules, scheduling logistics, house rules. All of it worth discussing out loud at the table. Almost none of it worth keeping as a standing document in that form, because nobody re-reads three pages once the campaign is rolling. By session four, the only part anyone still needs is the short list of "how do we handle X when it comes up" — and that part is usually buried on page two.

If you want the doc to still matter in month two, it has to be short enough that opening it feels free, not like homework.

A one-page version that holds up

Cut it down to five lines, each answerable in a sentence.

The vibe — one line on tone (pulpy, grim, comedic-with-teeth), so new players calibrate fast without reading a pitch document.

Lines and veils — what's off the table outright, and what fades to black instead of getting played out.

Spotlight agreement — how you handle a player going quiet for three sessions, or one player who wants to run every scene. Decide it now, not mid-argument.

Ruling authority — when the book and the table disagree, who calls it, and whether that call is final or revisited after the session.

Logistics — cadence, what "I can't make it this week" looks like, and whether the game pauses or runs short-handed.

That's the whole doc. Everything else from your session zero conversation — the pitch, the character creation rules, the safety tools discussion — can live in your notes as a one-time record. This five-line version is the part that earns a permanent spot somewhere you'll actually see it again.

Where you keep it matters as much as what's in it

Here's the part most groups get wrong: they write the doc somewhere separate from where they actually run the game — a Google Doc link pinned in Discord, a page in a wiki nobody has open. Separate means forgotten.

If you're already keeping your campaign notes and NPC tracking in GameMasterCraft, that one-page doc belongs in the same space, not a link away from it. The value isn't that GameMasterCraft makes the document fancier — it's that when your campaign notes and your table agreements live in the same place you're already opening every prep session, you actually see the agreement again instead of having to remember it exists.

Revisit it instead of just writing it

Write the one-pager once, then put a real recurring nudge on it: reread it at every level-up, every act break, or every time a new player joins. Two minutes, out loud if you can, silently if you can't. Campaigns drift — the spotlight agreement that worked for a four-player table gets tested when a fifth joins, and the ruling-authority line you set in session one might need adjusting once everyone knows the system better.

A session zero doc that gets revisited quietly does more work than one that gets written well once and never opened again. The one-page version isn't about being thorough. It's about being the kind of document your table will actually reach for when it matters — which, if you've run more than one campaign, you already know is usually right when someone's about to be annoyed at someone else.
