Phanerozoic is the current geologic eon that started about 530 million years ago. In this game, you will simulate the evolution of life on Earth during this time period. Starting with Trilobites and Algae, each player will try to influence the ecosystem by mutating and evolving plants and animals into new species to try to score points according to their unique goals. During the action phase, players will draft cards and play mutations, evolve species or use events to their advantage. Each round ends with a nature phase, where the ecosystem finds its balance as plants grow and animals feed. Will you cause the extinction of the dinosaurs or will you rejoice when inventive animals thrive? Phanerozoic is a thinky game that feels bigger than its box suggests. Components: 112 cards, achievement sheet, rulebook.
