Here is one faction of the humans!
And two mockup screens on three images. One mockup is about the planet screen and the other is the main screen.
On the planet screen you will notice that there is no buildings, just services.
This is something that I wanted to do for a long time, on games like this usually you have to build a lot of things on your planet, but even in Civilization it's kind of strange, to put some buildings on a city that should be something with thousands of thousands of buildings but was simplified to just a few.
Now imagine simplifying a planet to the same amount of buildings and you end up with Civilization on space where planets resemble cities.
So instead of a building, you have a service. You are going to pay a high maintenance value but you can stop and resume the service anytime you want.
A planet is divided into two resources, population and infrastructure.
If you have a population of 3.2 billion, then you maximum and ideal infrastructure is 3.2 points.
There are two ways for population to grow, by itself so if you have low population it will grow slowly and if you have a lot it will grow faster.
And population from other planets may also immigrate to your planet so you can end up with mixed population if your govern tolerates other races. But it can also happen between your own planets.
A planet has a maximum population limit, but it can be surpassed and will be. This will cause a lot of trouble so think careful before trying to make your population increase too quickly.
Infrastructure increases slowly because your civilians are always investing in your own race, you can however pay for a service that helps civilians to increase a planet's infrastructure.
If you have a population of 2 billion and an infrastructure of 1 point it means that your planet is actually performing most services at half of it's maximum performance.
So keeping infrastructure as close as possible from your current population will result in maximum output for that quantity of population.
So a planet with 3 billion and 3 points of infrastructure will result in X production for example and a planet with 6 billion and 6 infrastructure will result in 2X production.
This way planets that can hold an higher number of population will produce more.
Planets that increase their population too quickly will be penalized, planets that increase their population above the planet's maximum will also be penalized.
With this I can explain the population type.
For every 0.5 billion you will get one person that represents that population. This person is symbolic and you can use it to set their focus.
A planet with 3 billion will get 6 persons. There will be 5 types of person for you to specialize:
Civilian - Increases infrastructure
Farmer - Produces food
Builder - Gives production points (Used in some services like to build starships)
Businessman - Produces credit
Scientist - Gives technology points
So most of the early planets will consist basically of Civilians and Farmers, then move on to Businessman and Scientists, or Builders for planets that produce starships.
Planets will have specializations, after a certain criteria they will level up, depending on your current technology you will be able to specialize them to get bonuses.
Ship production will be made empire-wide, that means that you will produce ships using all your planets instead of each planet builds their own ships.
You can however choose in which planet the ship will appear or if it will remain on a pool. Ships in a pool means that they are deactivated so their maintenance costs are low and that if a war arises you can quickly activate them and spread them over your empire. If you keep all your ships active you will be able to respond more quickly to an war but it will cost more to maintain.
On the other mockup you can see some buttons:
