How to prep a session in an hour
Most prep time is spent on things the table never touches. Here is a repeatable hour that prepares the game your players will actually walk into — not the one in your head.
The short answer
Prep the table, not the plot. A session needs a strong opening, three or four situations with stakes, the handful of NPCs who might appear, and a clear sense of what the players are chasing. Everything else — the branching flowchart, the read-aloud boxes, the contingency for the door they will never open — is where prep time goes to die.
The one-hour framework
- Reread last time (5 min). Skim your last recap and notes. Write down the three threads the players left dangling — those are your real hooks, already load-bearing because the table cares about them.
- Write the cold open (10 min). One vivid situation that starts in motion. Not "you arrive in town" — "the town gate is barred and a man you recognize is arguing to be let out." Openings that start mid-problem save the first twenty minutes.
- Draft three or four situations, not scenes (20 min). A situation is a place, the people in it, what they want, and what happens if the party does nothing. Situations survive player choices; scripted scenes do not.
- Line up the NPCs (15 min). For each NPC who might speak: one line of voice, one thing they want, one thing they are hiding. That is enough to improvise the rest. Skip anyone the party is unlikely to meet.
- Name the stakes and tee up next time (10 min). Write one sentence: what are the players trying to accomplish tonight, and what changes if they win or lose? Then note one thread you are deliberately leaving for next session so you never start cold.
A worked example
The party is hunting a smuggler who fenced a stolen reliquary. Cold open: the fence is already dead when they arrive, still warm, the reliquary gone. Situations: the dockside tavern where he drank (a nervous barkeep, a witness who wants paying), the harbormaster’s office (records that place a ship leaving at dawn), and the buyer’s townhouse (guarded, a servant who can be turned). NPCs: barkeep — wheedling, wants the party gone, hiding that he moved the body; harbormaster — bored, wants a bribe, hiding nothing; buyer — gracious, wants the reliquary’s secret, hiding that he already knows who they are. Stakes: catch the ship before dawn or the trail goes cold across the sea. Left for next time: the reliquary is a fake, and someone swapped it.
That whole session fits on one page. If your prep does not fit on one page, you are prepping a novel, not a night of play.
Questions GMs actually ask
How long should it take to prep a tabletop session?
An hour is plenty for a weekly game once you prep situations instead of scripts. New GMs often spend three or four hours because they prepare for choices the players will not make; prepping a strong opening, a few situations with stakes, and the NPCs who might appear cuts that dramatically.
What should I prep first?
The cold open. A session that starts mid-problem — a door already barred, a body already cooling — buys back the first twenty minutes and sets the tone. Everything else can be improvised from a few well-defined situations.
How do I stop over-prepping?
Keep prep to one page and prep situations, not scenes. A situation (a place, its people, what they want, what happens if the party does nothing) survives any choice the players make; a scripted scene breaks the moment they do something you did not plan.
Where Storywright fits
Storywright keeps prep where the game happens. Tonight’s objectives, the NPCs in play, and the loose threads from last session sit on the session itself — linked to the people and places they mention — so the one-page framework above lives in the tool instead of a notebook you left at work. When the session ends, the same notes become the first draft of the recap. It is free to start, and free for your players forever.
