How will we feed our billions?
In Galactic Civilizations III, we presume that by the time we are colonizing planets, our home world has reached an equilibrium between food production and population. But let's face it: when we colonize other planets, it'll take many years for those planets to build up sufficient farming infrastructure to produce for the kinds of populations you have on your home world.
Galactic Civilizations III will be treating food a bit differently to reflect the awareness of just how important a large population is on your planets.
When Galactic Civilizations III first shipped, players built farms on planets and that would increase that planet's population. Because it was so easy to increase your population, our conversion between population to production was: production = the square root of population.
