Title: SimEarth: The Living Planet
Author: Will Wright
Rating: 4 of 5 stars
Sim Earth is a fantastic game by Will Wright, creator of the Sims and Spore. SimEarth was released by Maxis in 1990. As a 31 year old game, it's rough but lovable. It is based on the Gaia model and runs amazingly well on G3 Mac under OS 9.
The purpose of the game or simulation is to use energy and feedback loops to advance your chosen lifeform to the highest level of technology possible. It's easier said than done, but well worth the effort. You are pitted against not only your own created mishaps, but random events such as weather, cooling, warming, etc. It's a great primer on what it takes to make a planet full of life. Events are predictable, but not repetitive.
Earth isn't the only planet you can work with, the game includes scenarios for Mars and Venus. These are breathtakingly difficult. A simplified model called Daisy World highlights the power of the sun on Earth's environment. While it is meant to be a simulator type game, it dives into science fiction with some of the devices and creatures that appear.
Each world scenario is broken down into the world map which is initially populated with land forms. As time goes on, the landforms morph under the energy of the sun and tectonic forces. Sooner, rather than later, life will emerge. There are dozens of Taxa of life, all of which are on equal footing to evolve and become intelligent. These taxa and landforms are all right out of your Earth and Biology text books from high school, they feel familiar. You can use the magnifying glass to observe their description and current state. As creatures become intelligent, you can guide them through different levels of Civilization with the goal of getting them to colonize other planets.
SimEarth is educational in it's whimsy. You can bring back the Trichordates, a species of life with tri-radial symmetry. Or create Carniferns, man eating plants or even robotic life. All of these achievements have to be done between ice ages and hot, dry epochs. The game includes several scenarios which pose questions as to what hardships life can overcome with guidance or the limits of science. Terraform Mars and Venus, anyone?
