Once upon a time...

Edenland was once a lush paradise. Rivers, lakes, and waterfalls flowed freely across vibrant forests, home to a rich and diverse ecosystem. The five great regions of the territory coexisted in harmony with nature.

But the climate changed.

Decades of extreme heat and erratic rainfall have transformed Edenland into an arid, fragile land. Today, all five regions rely on a single underground aquifer—their last source of sustainable water.

The Dilemma

Each region must independently decide how much water to extract during each game cycle. Due to the distance and lack of communication systems, the decision is made in complete isolation—no communication, no negotiation.

There are two possible decisions:

• Option Y (Hydrology): a sustainable, long-term approach. If all regions choose Y, everyone will have water this cycle  (not too much, but some).

• Option X (Xerothermic): a high-gain, high-risk approach. If too many regions choose X (as much water as I can), some will go without water, as detailed in the rules: /rules/

The risk lies not in your own decision, but in the combination of everyone’s decisions. No one knows what the others will do. All you have is your reasoning… and your trust.
