There is a category of solo RPGs that don’t try to replicate the traditional tabletop roleplaying experience in solitude, but instead fully embrace their medium to offer something unique. IMAGINARIUM is one of them. Created by Linquant and available on itch.io, this solo roleplaying game offered as pay-what-you-want promises a narrative experience where imagination is the only limit. But does it really deliver? That’s what we’re about to find out.
IMAGINARIUM presents itself as a complete 40-page game, using a D10 system, three attributes, a Karma mechanic, and no fewer than ten oracles. Suffice it to say the slider is firmly placed on emergent storytelling rather than simulationism. Let’s dive into the guts of this system to see what it’s made of.
The foundation: minimalist character creation
Where some games ask you to spend an hour detailing your character on a character sheet, IMAGINARIUM strips creation down to the essentials. Your character is defined by:
- 3 attributes: Physique, Mental, and Equipment, rated from 1 to 5
- Karma: a narrative resource that starts between 5 and 8 points
- A stereotype: a sentence or two summing up who your character is
- An initial quest: what drives your character to act
No skills, no talents, no detailed inventory. This minimalist approach isn’t a flaw — it’s a deliberate design choice. It means every character is defined not by numbers, but by what they will experience over the course of the game. Your stereotype isn’t a rigid class — it’s a narrative compass guiding your choices.
Concrete example: say you create a character named Lyra, an « adventuring cartographer searching for a legendary city. » Physique 3, Mental 4, Equipment 2. Her modest gear (Equipment 2) means she travels light — a few maps, a dented compass, a knife. Her quest: discover the city of Eldoria. In just a few minutes, the stage is set.
The oracles: the engine of the unexpected
The beating heart of IMAGINARIUM is its oracles. Where most solo RPGs make do with a yes/no oracle and a single table (if they even have one), IMAGINARIUM offers ten.
These include an Actions oracle (what happens?), Locations (where am I?), Characters (who is involved?), Narrative Weather (what’s the mood?), and an Obstacles oracle. Some oracles are generic; others are specifically designed to inject twists into your story.
These oracles are freely available online at imaginarium.jnk.ovh/oracles — a valuable resource for trying the game without any investment.
The Actions oracle deserves special mention: with over 100 entries spread across a D100 table, it generates action verbs that feed directly into the narrative. Paired with a Themes oracle, it forms a particularly effective narrative incident generator.
The unique thing about these oracles is that they are never presented as fixed results. Each roll is an invitation to imagine — the game constantly pushes you to interpret the outcomes within the context of your story.
Action resolution
The resolution system is brutally simple: you roll a D10 and try to get a result equal to or lower than your attribute. Difficulty is represented by a threshold that modifies your roll:
- Standard difficulty (5-6): doable without stress
- Tense difficulty (7): the outcome is uncertain
- Hard difficulty (8): only the most skilled succeed
- Extreme difficulty (9-10): nearly impossible without help
What makes the system interesting is the ability to spend points from your attributes or Karma to influence the result. These points aren’t just a game currency: spending them carries a narrative cost. Losing a point of Mental means watching your character doubt themselves; losing a point of Equipment means breaking your gear.
Let’s come back to Lyra, our cartographer. She tries to scale a rock face to reach a lookout point. Difficulty 7, her Physique is 3. The roll: 8 — failure. Lyra could spend a point of Equipment (her rope snaps) to reroll, or a point of Physique (she gets hurt) to reduce the difficulty. Every problem becomes a narrative opportunity.
Karma: the mechanical-narrative linchpin
Karma is arguably the most elegant mechanic in IMAGINARIUM. It works as a pool of points that regenerates and is spent over the course of the story:
- You gain Karma by taking narrative risks, making interesting choices, or accepting the consequences of your failures
- You spend Karma to reroll a check, reduce a difficulty, or activate certain oracles
This risk → reward → narrative loop is the engine driving the game forward. It encourages the player not to play it safe all the time, but instead to embrace unexpected twists and turns.
Karma rewards narrative risk-taking: the more intense moments your character experiences, the more they gain the ability to influence fate. It’s elegant because it aligns mechanics with storytelling — you aren’t rewarded for winning, but for telling a good story.
Procedural scene generation
IMAGINARIUM offers a particularly effective scene generation system built around three elements:
- A location: drawn from the Locations oracle
- A narrative weather: the mood that makes the moment unique
- An obstacle: what stands between the character and their goal
This three-part combination lets you generate rich situations in the blink of an eye. Unlike a traditional random event table, this approach creates a minimal structure the player can embroider upon.
For Lyra, the first scene might give: The Echo Enclave (a canyon with whispering walls), Troubled weather (threatening clouds gathering), and an obstacle The Chasm (the bridge that once spanned the ravine has collapsed). In three rolls, a complete scene emerges: Lyra must find a way across this canyon before the storm, all while the whispering walls play tricks on her mind.
Strengths and weaknesses
Strengths:
- Accessibility: the rules fit in a few pages; you can start playing in under 15 minutes
- Replayability: with 10 oracles and hundreds of possible combinations, every session is unique
- Narrative fertility: the system constantly generates situations that call for creative interpretation
- Karma: an original mechanic that rewards narrative risk-taking
- PWYW format: the pay-what-you-want model makes it accessible to every budget
Weaknesses:
- Rare events: with a D10 system, probabilities are relatively flat and « narrative gems » — very rare outcomes — are less frequent than with a D20
- Layout: the presentation is functional but plain; you can tell it’s an indie production
- No bestiary: there are no monster or enemy tables — everything must be created by the player
- Limited support for long campaigns: the game shines in 1-to-3-hour sessions; managing long-term progression is entirely up to the player
Quick comparison
It’s hard to talk about a solo RPG without positioning it against its natural competitors. Here’s a breakdown:
- VS Ironsworn: Ironsworn is heavier, more procedural, with formalized quest progressions. IMAGINARIUM is far freer and more immediate. Where Ironsworn structures, IMAGINARIUM inspires.
- VS Pocket Quest: Pocket Quest bets on extreme simplicity and portability. IMAGINARIUM offers a richer oracle system and Karma mechanics that add a strategic layer absent from Pocket Quest.
- VS Mythic GM Emulator: Mythic is a general-purpose GM emulator. IMAGINARIUM is a complete game with its own narrative philosophy. Mythic is a tool; IMAGINARIUM is an experience.
Each has its place, but IMAGINARIUM stands out for its remarkable simplicity-to-depth ratio.
Conclusion
IMAGINARIUM is an excellent surprise. In a solo RPG landscape sometimes saturated with complex systems trying to simulate everything, this game takes the opposite bet: give players the tools to imagine, not to calculate.
Its Karma system is a small revolution in its simplicity, its oracles are varied and inspiring, and getting started is almost instant. Of course, not everything is perfect: the layout is modest, long sessions require personal investment, and you need to enjoy weaving stories from a loose framework.
But if you’re looking for a solo RPG that makes you want to pull out your notebook and write a story that’s entirely your own, IMAGINARIUM is for you.
