Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Act I of The Throne of Beasts is complete and fully playable from beginning to end. However, we want the community to take part in the evolution of Crônicas Improváveis from its earliest stages.

Our game combines author-crafted campaigns with an AI Game Master that narrates events, portrays characters, and responds to the player's actions in natural language. The game engine controls the story's structure and progression, while the AI brings the tabletop RPG experience to life.

Early Access will allow us to observe how different players interact with this system, identify unexpected situations, and improve the rules engine, narration quality, adventure pacing, and overall gameplay experience.

Our goal is to work alongside the community to build an increasingly polished, engaging, and accessible single-player tabletop RPG experience.”

Approximately how long will this game be in Early Access?

“We currently expect to remain in Early Access for approximately 12 months, although this timeframe may change depending on testing results and community feedback.

During this period, our focus will be on refining the RPG systems, expanding features, improving stability and the AI Game Master experience, and preparing the game for its 1.0 release.

Leaving Early Access will depend on the maturity and quality of the game's systems, rather than necessarily completing every campaign. Crônicas Improváveis is designed to continue receiving new stories and adventures even after its full release.”

How is the full version planned to differ from the Early Access version?

“We plan for the full version to offer a more polished, accessible, and comprehensive RPG experience while preserving the game's core concept: author-crafted campaigns guided by an AI Game Master.

Planned improvements include expanding the content based on SRD 5.1, with additional spells, creatures, and equipment; a tutorial for players who have never experienced tabletop RPGs; difficulty options; improvements to performance, stability, and AI Game Master consistency; and integrated tools to make reporting issues easier.

We also intend to explore the possibility of bringing the game to additional platforms.

At the same time, Crônicas Improváveis will continue to grow as a platform for different adventures. We plan to release new acts that continue The Throne of Beasts, followed by entirely new campaigns featuring their own stories, characters, and challenges.

It is important to clarify that new acts and campaigns will be sold separately as paid DLC. They are not automatically included with the original purchase or the free updates planned during Early Access.

Our goal is for version 1.0 to represent a complete and mature RPG system capable of supporting new adventures for years to come.”

What is the current state of the Early Access version?

“Crônicas Improváveis launches with Act I of The Throne of Beasts, an original dark fantasy campaign whose first act is fully playable, offering an estimated 10 to 20 hours of gameplay depending on each player's pace.

You create your character using rules based on SRD 5.1 and embark on an adventure guided by an AI Game Master that narrates events, portrays characters, and responds to your interactions in natural language.

The game already features turn-based combat with weapons, spells, and abilities; rules-based checks and dice rolls; character progression; equipment; recruitable companions; dialogue and negotiation; exploration and travel across a world map; a day-and-night cycle; resting; and an adventure journal.

The campaign follows a previously written and structured story, with planned characters, conflicts, objectives, and events. The AI guides the narrative experience within this structure, providing the natural interaction of a tabletop RPG without turning the adventure into a random or procedurally generated story.

Act I marks the beginning of a larger campaign, which will continue through future paid acts.

The game is initially available for Windows, with interface text, written content, and voiced narration in Brazilian Portuguese, English, Spanish, and Simplified Chinese.

The AI Game Master requires an internet connection to function.”

Will the game be priced differently during and after Early Access?

“We do not currently plan to change the base price of Crônicas Improváveis when it leaves Early Access.

The initial purchase, priced at US$29.99, includes the game, Act I of The Throne of Beasts, and 450 turns with the AI Game Master. This amount is designed to allow players to experience the first act, although actual consumption may vary depending on individual pace and playstyle.

Because the Game Master uses artificial intelligence to process interactions, each turn submitted by the player consumes one unit from their available balance. If narration fails, the turn is refunded.

Once the balance is exhausted, additional turns must be purchased to continue playing. Top-ups will be available exclusively through Steam:

Explorer's Pack: 150 turns for US$9.99.

Hero's Saga: 450 turns for US$29.99.

There are no monthly fees or subscriptions. Top-ups are one-time purchases, made only when the player needs them. If the costs of providing the AI service change significantly, top-up prices may be adjusted with advance notice.

New acts and campaigns will be sold separately as paid DLC. The base game purchase does not include these future expansions.”

How are you planning on involving the Community in your development process?

“The community will play an important role in the development of Crônicas Improváveis throughout Early Access.

We will use the Steam Community Hub to follow discussions, answer questions, receive suggestions, and publish news, updates, and development information.

Because our game features an AI Game Master, each player's experience may reveal interactions and situations that were not anticipated during internal testing. We want to learn from these experiences to identify issues, improve the Game Master's responses, refine the rules, and make campaign progression increasingly consistent.

Players will be able to report issues and share unexpected AI behavior through the Steam Community Hub. We also plan to implement an in-game bug reporting tool that will allow relevant interaction details to be sent directly to the development team.

Community feedback will help shape our priorities for bug fixes, usability improvements, difficulty adjustments, and new features.

We will also work to preserve save game compatibility across updates and communicate in advance about any changes that could affect existing saves.

We want the community to follow the evolution of Crônicas Improváveis and help us make the single-player tabletop RPG experience better with every update.”

About This Game

About This Game

Experience tabletop RPG adventures. At your own pace, with your own AI Game Master.

Crônicas Improváveis is a single-player RPG that combines epic, author-crafted campaigns with the experience of playing alongside an AI-powered Game Master.

Create your character, embark on a grand adventure, and experience a story filled with danger, discovery, conflict, and memorable characters.

Just like in a traditional tabletop RPG, the Game Master guides the adventure while you roleplay your character. The difference is that you don't need to gather friends, coordinate schedules, or wait for your next session. Your adventure is ready whenever you are.

A Real Story, Guided by an AI Game Master

In Crônicas Improváveis, campaigns aren't randomly generated stories invented by artificial intelligence.

Every campaign is written by authors, with a structured plot, characters, events, objectives, and a planned conclusion.

The game engine controls the adventure's progression, keeping the story coherent from beginning to end. Artificial intelligence takes on the role of Game Master: narrating events, portraying characters, and responding to your actions and dialogue without changing the story that was written.

You don't need to invent what happens next, create your own quests, or tell the Game Master where the adventure should go. Just like in a tabletop RPG, the Game Master presents situations and guides the campaign. Your role is to experience that story.

Your Character. Your Words. Your Adventure.

Instead of relying solely on predetermined dialogue options, you can speak to characters and express your actions in your own words.

Ask questions, negotiate, investigate, question motives, confront others, and roleplay your adventurer as you wish within the situations presented by the story. The AI Game Master understands your intentions and responds within the campaign's context and rules.

And all of this takes place in an RPG with real gameplay systems, character progression, and meaningful challenges:

  • Create your character: choose your race, class, attributes, and abilities to bring your adventurer to life.

  • Explore and interact: discover locations, investigate events, and talk to the characters you encounter throughout your journey.

  • Face danger: engage in combat, wield weapons, cast spells, and use abilities, with outcomes determined by the game's rules.

  • Grow stronger: earn experience, level up, acquire equipment, and develop new abilities.

  • Find allies: meet characters and companions who will become part of your journey and the events of the campaign.

This isn't an open world of infinite stories. It's a genuine RPG campaign, crafted to be experienced with the natural flow of a tabletop adventure.

Your First Campaign: The Throne of Beasts

Your home has been destroyed. Your former life has come to an end. And what seemed like an isolated tragedy is only the beginning of something far greater.

Armies of men and beasts advance through unprepared lands, leaving destruction and survivors in their wake. As rumors of a usurper spread, your journey begins as a desperate struggle for survival and gradually becomes a search for allies against a growing threat.

The Throne of Beasts is an epic fantasy campaign featuring memorable characters, conflicts, alliances, and a sweeping story waiting to unfold.

The game begins with Act I, offering approximately 10 to 20 hours of adventure, depending on each player's pace.

This is the first act of a larger story. Your journey will continue with the release of future acts.

One Game. Many Stories to Experience.

Crônicas Improváveis is designed to be more than a single adventure.

Over time, we plan to release new acts that continue existing campaigns, as well as entirely new campaigns featuring their own stories, characters, settings, and challenges.

All within the same game, using the same RPG system and AI Game Master.

So, after experiencing one story, you can return to continue your journey or embark on a completely different adventure.

New acts and campaigns will be released as paid DLC, sold separately. The base game includes Act I of The Throne of Beasts.

How Do Turns and Top-Ups Work?

To provide an experience with an AI Game Master that narrates and responds to your interactions, Crônicas Improváveis uses a turn-based credit system.

The base game includes 450 turns, an amount designed to let you experience Act I of The Throne of Beasts. Actual usage may vary depending on your pace and playstyle.

Each interaction you send to the Game Master consumes one turn, regardless of how many AI operations are needed to process it. If narration fails, the turn is refunded.

If you run out of turns, you'll need to purchase additional credits to keep playing. Top-ups are sold exclusively through Steam in two packages:

  • Explorer's Pack: 150 additional turns.

  • Hero's Saga: 450 additional turns.

There are no monthly fees or subscriptions. You purchase additional turns only when you need them, and you can check your remaining balance in-game.

Turn credits are separate from purchases of new acts and campaigns, which will be offered as paid expansions.

Crônicas Improváveis — Stories crafted for you to experience. An AI Game Master to guide every adventure.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Crônicas Improváveis uses generative artificial intelligence in two ways.
During development: AI tools assisted in the creation of visual assets (portraits, scene illustrations, interface elements, and icons), the opening video, music, sound effects, written content, and translations.
The campaigns are pre-structured narrative works, with plots, characters, conflicts, scenes, objectives, and events defined under the developer's creative direction. Artificial intelligence is used as a production support tool, while the development, organization, review, and finalization of the campaigns are overseen by the developer. Stories are not randomly generated during gameplay.
During gameplay: an AI Game Master generates the narration for each turn, portrays characters, responds to the player's dialogue and actions, and presents suggested actions. An AI-generated voice can also read the narration aloud.
The campaign's structure and progression are controlled by the game engine, not by artificial intelligence. Mechanical outcomes, including dice rolls, damage, success, and failure, are determined by a rules engine based on SRD 5.1.
The AI Game Master guides the narrative experience within the pre-written campaign, without creating new storylines or freely modifying its structure and fundamental events.
Content generation is subject to safety restrictions and predefined limits established by the game, including mechanisms that prevent the generation of sexual content.

Mature Content Description

The developers describe the content like this:

Crônicas Improváveis is a dark fantasy tabletop RPG. Turn-based combat with weapons and magic is frequent: characters are wounded and die, and the story deals with war, massacres and burned villages. Violence is told in text and narrated voice over static illustrations. In one optional moment the player may choose to torture a captured enemy for information; it is described in text and never shown. Some dialogue contains strong language. The narration is generated live by AI within fixed content limits: it never produces sexual content, and the game has no nudity.
