Getting Started
Press 
on the Title Screen to start the game.
If there is save data, the options NEW and CONTINUE will be available. To play from the beginning, select NEW. To pick up where you left off, select CONTINUE.
When starting a new game, first select the difficulty level.
"E" indicates the maximum energy level. Energy is used every time you input a command, and it recovers as time passes.
In Experimental, you can use an unlimited amount of energy.
In a Hard Game, the values in the Model Control Panel are set randomly.
After confirming the difficulty, select a scenario and the game will begin.
The game ends after 10 billion years.
Basic Play
Game progress is divided into 4 TimeScales based on the planet's status. Each TimeScale has its own goal - another step in the development of the planet.
First try to achieve the following goals.
Consult the Reports and all of the Graphs, then make use of the various Buttons to adjust the planet's environment until it is fit to sustain life.
Start by adjusting the planet's geological and atmospheric conditions to encourage the formation of continents and oceans - the ideal conditions for spawning new life forms.
Once life forms have appeared, set their adaptability, reproduction speed, mutation rate, and other factors to stimulate their evolution.
When intelligent life forms appear, adjust their Energy Investment and Energy Allocation as you guide them through an Industrial Revolution to the Industrial Age. Then take them beyond and work toward the Nanotech Age.
Once a civilization reaches the pinnacle of its development, it will initiate an Exodus and set off from the planet to settle other worlds.

Civilization Model
Civilization develops as you allocate energy generated from Energy Investment on the left to the Energy Allocation items on the right.
Energy Investment
 |
This energy is produced by physical labor in addition to other sources and becomes more efficient as time goes on. However, it also gives off carbon dioxide. |
|---|---|
 |
This energy is created by harnessing the power of sunlight and wind. It's not very efficient, but since it has no drawbacks, why not use it to its fullest? |
 |
This energy is created by harnessing the power of water and geothermal heat. It's not very efficient, but since it has no drawbacks, why not use it to its fullest? |
 |
This energy is created from petroleum and boasts the highest efficiency for the Industrial Age and beyond. There's a finite amount, however, and using fossil fuels will lead to increased pollution and carbon dioxide. |
 |
This energy is produced from nuclear power and is almost as efficient as fossil fuels. While it doesn't produce pollution or carbon dioxide, supplies might dry up or a reactor might melt down. |
Energy Allocation
 |
Setting this high will promote the development of philosophy and lower the frequency of war. |
|---|---|
 |
Setting this high will promote science, enabling the development of an advanced civilization. This must be high in order to advance to the next TimeScale. |
 |
Setting this high will increase food production and lead to an increase in population. |
 |
Setting this high will promote the development of medicine and lower the frequency of plague outbreaks. |
 |
Setting this high will promote the development of the arts and increase the quality of life. |

Event
Events occur naturally all over the planet, but you can trigger events on your own with the Disaster Button.
Events You Can Trigger
 |
Increases rainfall in the area, and destroys life forms and cities. Occurs naturally when the water temperature is high. |
|---|---|
 |
Destroys coastal cities and life forms. Sometimes occur after earthquakes. |
 |
Creates craters on the planet's surface and sends dust into the atmosphere. |
 |
Volcanoes can elevate the terrain and create islands. Because they produce a lot of carbon dioxide and dust, volcanic eruptions can dramatically change a planet's temperature. |
 |
Causes a nuclear explosion, destroying life forms and cities in the area. Radiation from the blast will damage all life forms. |
 |
Consumes oxygen and increases carbon dioxide, destroying life forms and cities where it occurs. Occurs naturally when the oxygen content of the atmosphere is high. |
 |
Triggers an earthquake in the direction of the indicated seismic waves. Also affects continental drift. |
 |
Destroys life forms and cities in the area by infecting them with a plague. Happens more often when Medicine in the Civilization Model is low. |
Other Events
These events occur naturally when certain conditions are met. You cannot trigger them yourself.
  |
Pollution will occur in cities that have developed to a certain point. Severe pollution can damage life forms. |
|---|---|
 |
War will destroy surrounding cities. Occurs more often when Philosophy in the Civilization Model is low. |
 |
Occurs after a nuclear explosion, making the surrounding area uninhabitable. As time passes, the area will recover, or you can flood the area to wash it away. |
 |
An Exodus is underway. Once complete, the planet will no longer be home to any civilization. |
TimeScale
Within the game, the measure of time varies depending on the TimeScale.
Once you achieve your goal, you will proceed to the next TimeScale and receive a new goal.
Geologic
This TimeScale covers the stages from the birth of a planet to the appearance of life. You will move on to the next TimeScale once multicellular organisms have evolved.
Evolution
As the multicellular organisms continue to evolve and mutate, many different life forms will populate the planet. When one of them reaches the fire-wielding Stone Age, you will move on to the next TimeScale.
However, in order to develop a civilization, you will need land and an environment suitable for life forms.
Civilized
Help civilization evolve from the Stone Age through an Industrial Revolution to the Industrial Age to move on to the next TimeScale.
From this point on, you will be working to see how much further you can develop your civilization.
Technology
Once you help a civilization evolve beyond the Industrial Age to the Nanotech Age, it will trigger an Exodus. All of civilization will leave to settle on another planet, and the planet will return to the Evolution TimeScale.
Scenarios
This game includes 8 scenarios.
Beginners should set the difficulty to Experimental, select Random Planet, and start from the Geologic TimeScale.
To complete the MARS and VENUS scenarios, you must reach 25,000 total life forms and a civilized population of 1 billion within 500 years.
Until you solve certain problems, you can only use the Civilization Model portion of the Model Control Panel.
Random Planet
Choose 1 of the 4 available TimeScales.
You have full access to all of the settings in the Model Control Panel, so have fun making your own unique planet.
AQUARIUM
Build land from scratch on a planet formed entirely of water.
Stag Nation
Work with a model Earth, starting with life forms that have reached the Stone Age. Increase the amount of land and improve Energy Investment to build a more advanced civilization.
EARTH: The Cambrian Era
This scenario replicates the Earth 550 million years ago. Watch as massive landforms slowly break apart into the continents of today.
EARTH: Modern Day 1992
This scenario uses a model of Earth from 1992. Civilization has progressed and an Exodus is right around the corner, but there are many problems that need to be solved first.
MARS
The goal of this high difficulty scenario is to make Mars a planet capable of supporting life.
VENUS
The goal of this scenario is to develop Venus into a planet capable of sustaining life. This is the most difficult scenario of all.
DaisyWorld
This scenario is a simulation based on the Gaia theory which says that the atmosphere, oceans, soil, and all living things are interconnected and sustain the planet together. There are no goals other than growing Daisies.
The Daisies in this scenario illustrate the relationship between atmospheric temperature and flower color.
