A sort of combination of Civilization and SimEarth. You control one of the
earliest tetrapods (land animals), and try to get it to reproduce, spread, and
evolve into a later species, ultimately evolving an intellectual species
(which doesn’t have to be Homo sapiens). There are some 160-odd species in the
game, including dinosaurs; the continents move around during play; era changes
are marked by geological catastrophes, which occur on a semi-random basis. In
addition to the ‘full’ game, there are shorter scenarios for the Paleozoic,
Mesozoic, and Cenozoic.
