Build your own ecological network in Ecosystem, a biologically-derived card drafting game. Players, choose, pass, and arrange 11 different card types consisting of organisms ranging from bees to bears and environments like streams and meadows. Earn points by aligning animals with habitats where they most flourish. Biodiversity is rewarded while monocultures are penalized. Each time you play, you build one-of-a-kind ecosystem, striving to balance the delicate connections between all living things.
