It’s round about 4 billion years ago. Earth has just recently cooled off enough to have water on its surface. Impacts of comets and meteorites have almost ceased. The sky is orange and dense with thick clouds, through which a faint Sun barely shines. A vast, greenish, muddy ocean covers almost the entire planet. The little dry land is black volcanic rocks and barren. But deep in the ocean and in a few oases, something is cooking: life is about to emerge. In AEON, you and your friends represent prebiotic environments where Life might have emerged. Together, you build a network of chemical reactions that transforms simple prebiotic reactants into complex molecules. Eventually, these molecules will allow you to establish the basic mechanisms of life which make the reactions more efficient. The first player to create all the requirements for the emergence of biological evolution wins the game. —description from the designer
