Happiness

Overview

There are a wide variety of factors that contributes to the happiness of the colonists or natives of a planet. These factors include taxes, population, planetary structures, climate (for colonists), and government (for natives).

The change in happiness for non-Crystalline colonists is as follows, where r is the tax rate, p is the population, m is mines, f is factories, and t is temperature:

$\operatorname {happyA} =trunc({\frac {1000-80r-{\sqrt {p}}-{\frac {m+f}{3}}-3\mid 50-t\mid }{100}})$

The change in happiness for Crystalline colonists is as follows, with letter identification is identical to above:

$\operatorname {happyB} =trunc({\frac {1000-80r-{\sqrt {p}}-{\frac {m+f}{3}}-3(100-t)}{100}})$

The change in happiness for natives is as follows, with the above identification, plus g being the government:

$\operatorname {happyC} =trunc({\frac {1000-85r-{\sqrt {p}}-{\frac {m+f}{2}}-50(10-g)}{100}})$

Impact

What impact the happiness will have is dependent on the happiness level after it has been changed. Apply all of the following as appropriate:

• Below 70 - No growth
• Below 40 - Rioting: If the colonists are rioting, then they will destroy 10 mines and 8 factories. Likewise, if the natives are rioting, then they will destroy 5 mines and 3 factories.
• Below 31 - No taxes may be collected. Also applies if below 31 prior to the change. Natives may not be taxed while below 31.
• Below 0 - Civil war: For each civil war, colonists and natives will kill each other (by 30% plus 100 clans), and destroy 10 mines and 8 factories. There may be two civil wars on the same planet, if both happiness levels are below 0
