Most open-world games hand you a sword and a health bar. The world has a problem; you hit it until it stops being a problem.

The Codex Files is the opposite. A village's crops fail. You don't fight a blight-monster. You gather soil, run a small experiment, and decide what actually happened — drought, blight, or a bad deal upstream. The answer unlocks the next node on the map.

Three paths (science, negotiation, investigation) intersect on purpose. A business puzzle can need a science clue. A case can hinge on a conversation.

Levels scale with age so a ten-year-old and an adult can play the same world without one of them being bored.

If you've ever wanted Genshin's sense of place without the combat grind, this is the prototype of that.
