The author built their second MMORPG, **Migla**, using Fable 5. ### Core Info - The game is a lightweight, Runescape-style MMO featuring a shared town, woodcutting, fishing, smithing, combat, and multiplayer activities. - Development relied on typical "vibe coding": the author described requirements in natural language, and the agent continuously translated these ideas into code. - The entire project took **9 days**. The author mentions mostly playing and complaining while the agent turned those complaints into features. - The game is **completely free** and **MIT open-source**, with the repository now public. ### Highlights - It is a fully playable online project. - The post implicitly demonstrates the efficiency of AI agents in indie game prototyping and continuous iteration.
