The Story Engine is a card-based tool to generate endless, semi-random writing prompts. It’s is billed as a tool or multiplayer game to aid in writing fiction, playing tabletop RPGs, or just to be played on its own. It started out in 2019 as one of those Kickstarter projects that caught fire and got fifteen times as much money as they were asking for. Now, the full product is launched, along with myriad add-ons enabled by Kickstarter stretch goals.
As a writer, a TTRPG player, and general lover of boxes of cards with nice art, I decided to try it out.
What’s in the Box
The main box comes with 180 cards. There are also three 60-card “expansions” that can be purchased separately: sci-fi, fantasy, and horror; and six 18-card sub-genre “boosters” for cyberpunk, steampunk, eldritch horror, post-apocalyptic, mythological and dystopian. I went for broke and got the whole collection. The core set is genre-agnostic, but the add-ons are clearly focused on speculative fiction.
The build quality is solid, which I appreciate as someone who has accumulated quite a few board and card games of varying quality. The box is a sturdy, fold-open affair that latches with magnets and has a sleeve. The cards are glossy, nicely weighty paper, and the illustrations are evocative. The cards aren’t plastic-coated, so expect the edges to get roughed up as they’re repeatedly shuffled.
How Does it Work?
The cards are divided into five different types: Agents, Engines, Anchors, Conflicts and Aspects.
- Agents represent characters
- Engines represent a goal or desire
- Anchors represent places, things, and ideas
- Conflicts are challenges or difficulties
- Aspects are adjectives
In its simplest form, I can play one card of the first four types, in sequence, to generate a random prompt, such as
A daredevil (agent) wants to enact a secret plan revolving around (engine) an election (anchor), but they will bear the scars for all to see (conflict).
I can then customize that prompt in two ways. First, each card has 2 or 4 prompt phrases depending on type, so it can be turned 90 or 180 degrees to change the “active” phrase facing me to something more inspiring. Secondly, I can add an Aspect. Since aspects are adjectives, they can be applied to the noun cards: agents (characters) and anchors (places, things, ideas).
With those changes, I might transform the first prompt into
A tormented fraud (agent + aspect) wants to unmask the conspiracy of (engine) a rebellion (anchor), but they will bear the scars for all to see (conflict).
The guidebook that comes in the main box also suggests ways to use the cards to generate character concepts, items and settings, as well as several more complex prompts that utilize more cards. These include things like conflicted characters with multiple goals, or two characters in conflict over related goals.
Finally, it includes rules for multi-player storytelling games and some helpful hints toward RPG players as to how the various prompts might be used in building campaigns, settings and scenarios.
Despite all these prescriptive rules for building prompts, The Story Engine is also happy to tell you that this doesn’t have to be rigid, with hard and fast rules. You can use the cards however you’d like.

My Experience
The Story Engine does a good job riding the line between too specific and too vague. I often find writing prompts irritating when they’re little more than a vague topic, but too much detail obviously takes any agency away from the writer.
I filled a few notebook pages using the “simple” writing prompts. Not all of the results were instantly inspiring, but I was able to glean a few ideas that feel promising, and a few more that seem like they could lead somewhere with a bit more time and thought.
The complex prompts include more cards and more structure, and as a result they are less open-ended and more inflexible. These are sometimes too detailed for me, feeling like there’s not enough room for filling in the blanks. However, you can always swap cards or break the rules to get something more to your liking.
The individual cards are also just fine as prompts by themselves. Sometimes a one-word character or setting description is all you need, especially when trying to flesh out an idea in progress. The pictures on the cards also do work as extra inspirational elements that don’t insert more words into the mix.
What about RPGs?
I’m not currently running a campaign, so I haven’t tried incorporating The Story Engine into one. However, I have used the similar dice-and-table-based prompts in The Perilous Wilds to run totally improvised one-shots of Dungeon World. I could definitely see using The Story Engine to do something similar.
If you have a home brew campaign, these prompts are probably going to be more useful than if you’re trying to add to a pre-written one. They might also be fun for generating NPCs on-the-fly when your adventuring party takes an unexpected turn.
Conclusions
So far, I’m pleased with what I’ve gotten out of The Story Engine, and I’ll continue to use it. My only concern is that the prompts might start to feel samey after a while. Even if there are technically billions of combinations, the cards will eventually become familiar. Still, with the core and add-ons, I have quite a few cards to work with. I think I’ll be using these cards as a story brainstorming tool for a long time.
If you’re unsure, the core set is a good starting point, and it’s genre-agnostic. If you’re not writing speculative fiction, the add-ons don’t offer much. If you are writing spec-fic and The Story Engine sounds exciting to you, buying one of the bundles gets you a pretty steep discount vs. buying piecemeal.

Generally I turn up my nose at these sorts of things but this looks pretty sweet

There is something nice and tactile about cards – shuffling, dealing and turning them. It’s too bad they don’t have a superhero-themed add-on for you.

I should maybe mention here that the Story Engine folks have a new project on Kickstarter with 5 days left – it’s called The Deck of Worlds, and it’s the same sort of thing, but focused on world-building. https://www.kickstarter.com/projects/rockpapercynic/the-story-engine-deck-of-worlds
Plus, it looks like they’re planning on releasing more add-ons for other genres, including a superhero pack.
