Simpedia: SimEarth


The Living Planet

Take charge of an entire planet from its birth until its death - 10 billion years later. Guide life from its inception as single-celled microbes to a civilization that can reach for the stars. Inspired by James Lovelock's Gaia hypothesis, Sim Earth simulates the Earth as a single living organism. Manage your own species and civilisations through the trials of warfare, pollution, famine and disease in a real-life battle where only the fittest will survive.
