Boundless AI Fantasy

Boundless AI Fantasy is an indie RPG developed by a single person as a personal project. It pairs roleplaying narrated by language models with turn-based tactical combat. Players create their own campaigns using an in-game editor, defining locations, world descriptions and characters, each with stats, background descriptions and skills. This written material is passed to the AI as the context from which it narrates, so the content players author shapes how the story develops during play.

Combat can be initiated whenever the AI is idle by pressing the Start Combat button. The view then switches to an isometric, grid-based battlefield constructed from the player’s current location and populated with the characters present. Battles involve coordinating movement, making use of range and deploying skills. Characters gain experience and level up through combat victories and quest completion.

The AI models run entirely on the player’s own hardware, with no cloud services, subscriptions, accounts or API keys required, and no data leaving the PC. Two open-source models, Google Gemma 4 in e2b and e4b variants, are included with the game. Players may also configure the game to use their own model, provided it is in a format supported by HuggingFace Transformers or GGUF with llama.cpp.
