JevMade field notes / Game architecture walkthrough

A virtual world that separates AI choices from long plans

This guide explains how to run a virtual civilization that separates long-term software planning from immediate choices. It shows how to set up the simulation, review past actions, and manage the private access codes needed for different tools.

Our summary

This project is a virtual world simulation where digital characters live, work, and build a civilization. Someone would use it to explore how software handles tasks when its long-term planning is kept completely separate from its immediate, everyday choices.

The simulation uses an AI tool called Jev to make fast choices from a set of allowed options, rather than writing out text. An optional separate text program can suggest longer plans, but Jev always makes the final recorded decision before anything actually happens.

This setup is useful for people who want to track exactly why software took an action. However, a valid choice does not guarantee useful behavior. In tests, characters sometimes repeated tasks endlessly. Also, the standard internet-based planner was not tested with a live connection.

Key takeaways

Assign immediate choices to Jev and leave long-term planning to a separate optional text program.
Start with a pre-made world or a clean slate to see how different choices play out.
Keep track of which private access codes are needed for choices and which cost extra for planning.
