🧾Note on Format

This is a prompt-based solo strategy game designed for use with ChatGPT (or compatible LLMs). It plays like a hybrid of card game and baseball simulator—entirely through text interaction.  

While not a physical game in the traditional sense, it follows the format of tabletop toolkits and solo RPG modules, making it a perfect fit for fans of narrative systems and card-based tactics.
