Aevum – Free AI RPG engine for Claude with persistent factions and economy (github.com)

Arcanum RPGs has launched Aevum Realm Architect, a free AI-driven RPG engine designed for use with ChatGPT, Claude, or Gemini. This immersive game lets players start as a serf with limited resources, progressively advancing to monarchy through strategic trade, diplomacy, and warfare. The uniqueness of Aevum lies in its deterministic mechanics, where outcomes are determined by player choices and planning rather than chance, accompanied by a detailed 30,000-word Atlas outlining the lore, geography, and economics of five historically inspired nations. Significantly, Aevum introduces a "Deference Engine," enforcing a medieval social hierarchy that affects player interactions and consequences based on their status. This adds depth to the gameplay experience, making players' advancements feel genuinely earned. Additionally, the game features a tag-based economic system that allows for meticulous management of resources and forces. With autonomous faction progression and deterministic combat mechanics, Aevum Realm Architect embodies a new paradigm in AI RPGs, merging intricate storytelling with engaging gameplay while remaining freely accessible to enthusiasts interested in leveraging AI models for creative pursuits.
