We built a simulation engine (currently on iOS & Android) that allows the community to create and share text adventures populated by multiple LLM-based agents. Unlike standard chatbots, our focus is on community co-creation—users define the worldviews, and our agents (with persistent memory and social relationships) bring them to life.
The cool part:
We implemented a system we call "World-Line Divergence" (inspired by visual novels like Steins;Gate). Usually, AI RPGs feel random or infinite loop. We built a state machine that tracks "World Deviation." If players interact with NPCs in specific ways (e.g., convincing an artist to change their style), it triggers a graph switch, leading to a completely different generated ending, effectively breaking the original script.
Tech Stack:
- Backend: Python / Java with a custom AI orchestration framework (to handle agent concurrency).
- Models: Hybrid routing between Gemini, GPT, and DeepSeek (optimizing for cost/performance based on task).
- Vector DB: Milvus (for handling long-term agent memory).
We are currently live on App Store and Google Play. Since it's a mobile-first experience, the link leads to our landing page where you can see the demo flow.
Would love to hear your feedback on the "World-Line" concept: Does this state-machine approach solve the aimlessness of AI RPGs?

It's possible this developer didn't want to do that, so they chose to not publish in the EU.

You won't be able to actually read the mail though, so depends on the seriousness of the project. If it's an actual business then best get a proper business address.
Or at least get the higher tier where they scan your mail and send it to you.
