Your Second Life, Brought to You by GPT-4

What it does LifeReloaded is an interactive text-based life simulation where an LLM acts as the narrative engine. Players receive random birth attributes, an MBTI personality, and a unique AI-generated poem, then make choices through procedurally generated life stages until they die and receive an epitaph. The project exists in two forms: a prompt file run inside ChatGPT’s Advanced Data Analysis, and a web application powered by GPT-3.5-Turbo.

The interesting bit Rather than scripting events, the authors use prompt engineering to turn the model into an improvisational game master that enforces mechanics like a roughly 10% chance of “multiverse” special events—aliens, time travel, child stardom—which can permanently hijack the narrative. It is essentially a sophisticated prompt template wrapped around OpenAI’s API, which is both its charm and its architectural reality.

Key highlights

• Real-time narrative generation: every event and choice is generated by the LLM rather than drawn from a hardcoded story graph.
• Personality mechanics: MBTI typing influences available choices and character behavior.
• Rare special events: approximately one in ten rounds triggers a multiverse scenario that can completely shift the setting.
• Poetic bookends: each life begins with a unique AI-generated poem and ends with a personalized epitaph.
• Non-commercial open source: released under CC BY-NC-SA 4.0.

Caveats

• The ChatGPT version is essentially a single long prompt file (LifeReloaded.txt) that requires a paid ChatGPT Plus subscription with Advanced Data Analysis enabled.
• The README is heavy on feature lists and light on technical architecture; the web version’s internals beyond app.py and an API key are largely unexplained.
• The authors explicitly warn that LLM randomness causes gameplay to fluctuate, and that special events are entirely unpredictable since they are fully AI-generated.

Verdict Worth exploring if you are studying prompt engineering for interactive fiction or prototyping LLM-driven narrative games. Give it a pass if you want deterministic mechanics, a self-contained engine, or a production-ready backend.
