Polyzonia is an upcoming ecosystem simulation game set in the Amazon rainforest, where players gradually establish a self-sustaining environment. It matters because it aims to make plants and animals active parts of an interconnected ecosystem rather than simple decorative elements, while giving players direct influence over life cycles and food chains.

Players choose a biome, add plant life and introduce animals such as capybaras and jaguars, initially managing individual actions through clicks. They can also intervene at a smaller scale, including pollinating flowers or helping frog spawn reach water, before automation allows the rainforest to sustain and develop independently. The game has no release date yet, but is available to wishlist on Steam.
