Saga & Seeker, the TRPG-Style Free-Input RPG That Turns Any Input into 'Your Own Story' with AI, Adds Ultra-Premium Model 'Claude Fable'!

Saga & Seeker, a text-only RPG that uses text-generation AI to create a 'TRPG-style' narrative based on players' 'free input,' has released its v1.2.1 update on July 15.

This update adds support for the latest GPT-series AI models, including the highly anticipated 'Claude Fable,' known for being 'too powerful.' Additionally, models from Grok and Deepseek, previously unsupported, have now been integrated.

The newly added 'Claude Fable' is a premium model specialized in creative storytelling, while models like GPT Luna offer high-quality output with unprecedented cost efficiency, allowing players to enjoy extensive gameplay affordably. This update primarily introduces more budget-friendly models, enabling users to select AI narrators that better match their preferences and needs.

We invite you to craft your own unique story with your favorite narrator!

◆ Game Play Trailer:

Saga & Seeker (shortened to 'SagaShika') is a story-crafting game that digitizes the character-play experience of 'TRPGs' using text-generation AI, allowing players to create their own personal narratives. Unlike traditional games with fixed choices, players directly write what they want to do, and characters react to their input, advancing the story.

Additionally, the 'Saga & Seeker Official Portal Site' allows players to upload original characters and scenarios, and publish their gameplay logs for anytime review.

The portal site is mobile-compatible, enabling players to revisit their stories anytime, anywhere, with an interface nearly identical to the in-game experience.

◆ Six New AI Models Added! Enjoy More Flexible Storytelling

Version 1.2.1 introduces six new AI models. Each AI narrator has unique strengths and stylistic characteristics, allowing players to select based on personal preference.

The full list of newly added models is as follows:

Claude Fable 5

GPT-5.6 Sol

GPT-5.6 Terra

GPT-5.6 Luna

Grok 4.5

Deepseek V4 Flash

Saga & Seeker plans to actively support new AI models in the future. Experience highly immersive storytelling powered by cutting-edge AI!

Saga & Seeker Game System Overview

・ Simple gameplay: Just write what you want to do

The game progresses through repeated cycles of 'narrative descriptions' by text-generation AI and 'action inputs' by the player. Input content is entirely up to the player, and the AI weaves a story based on any input.

・ Character creation via free input

In Saga & Seeker, not only the player's character but also party NPCs can be fully customized from scratch. Detailed customization of stats and skills is possible, and character background text can be freely written. These texts are directly reflected in gameplay by the AI, creating unique stories for each character.

・ Unlimited customization of experiences through imagination

'Skills' and 'memories' earned upon quest completion are automatically generated by AI based on quest content, accumulating unique experiences for each character. Character data can be edited anytime, and for those seeking deeper experiences, a feature to load original quests is available.

・ Share your creations

Original characters can be enjoyed personally or shared with other players via character sheet import/export functions. Upon quest completion, an HTML 'quest log' is generated, viewable on smartphones and shareable online.

◆ About Generative AI Usage

While this game uses text-generation AI as part of its system, all in-game illustrations, sounds, and other assets are created by human creators. No AI-generated assets are used except for the generated text within the game.

Saga & Seeker aims to be a game where players and creators can unleash their imagination to craft their own stories.

Dagdoria Studio Overview

Dagdoria Studio, a game development studio with the concept of 'rough-cut, therefore fascinating,' was founded on the desire to deliver 'new theme' games in their raw, unpolished form without sacrificing fun.

Saga & Seeker is a work that harnesses generative AI as a new toy.

Generative AI is notoriously difficult to control, yet it also has the fascinating potential to produce results beyond imagination. By deliberately avoiding safe, polished outputs and delivering this 'wild horse' as-is, we hope users can experience the charm of 'rough-cut, therefore fascinating.'

Dagdoria Studio will continue exploring beyond generative AI, digging for undiscovered gems of fun.
