The Design and Functionality of ChatRPG v1

The debut version of ChatRPG, v1, embarked on its mission with the support of OpenAI’s GPT-4. It leans heavily on static prompt engineering to drive interaction. Each player interaction is processed by sending the full conversation history to the LLM, which classifies inputs into “Do”, “Say”, and “Attack” prompts, attempting to simulate the adaptive responses one would expect from a human GM.

However, the system is not without its limitations. As discussed in the paper, the growing size of prompts can lead to context loss and inconsistencies in narrative memory. Over time, this impacts the coherence of storytelling, especially as prompts reach context window exhaustion.

• Uses a stateless API with full-context prompts
• Fixed role prompts for “Say”, “Do”, and “Attack”
• No persistent world state management
• JSON-structured outputs
• Combat handled via scripted logic
• Limited narrative adaptability
• No agent separation
• Prone to forgetting previous story beats
• Player inventory tracking issues
• User study with N=8 showing fun but flawed gameplay
• High replay value despite design issues
• Context window exhaustion over time
• Simple character and environment modeling
• Lacks real-time decision reasoning
• Minimal modularity or extensibility

Despite these constraints, the pilot study highlighted aspects of enjoyment among users, pointing to the inherent fun of interactive storytelling. However, participants also expressed a desire for more coherence and adaptive storytelling that could dynamically respond to their inputs and decisions. These insights were instrumental in steering the development toward a more agentic design in ChatRPG v2.

From the feedback, it became clear that while ChatRPG v1 succeeded in engaging players, it lacked the depth and responsiveness necessary for sustained solo play. This realization underscored the need for a profound redesign, paving the way for ChatRPG v2—an agentic system designed to address these challenges and enrich the solo RPG experience.
