While reading one of my post I notice that someone said that the population of the planet are all killed by fighting to the death, and the planet is repopulated by the soliders, but it does not seem right. Frogboy or any other dev do you have the answer for this?
I believe I said that, yes. It fits, though. Consider: You invade the planet. The number of defenders coincidentally happens to be equal to the listed population of the planet. They fight very poorly, probably because they were not equipped or trained to be soldiers, allowing you to take the planet with maybe a tenth of the invading force that they would have. After the fighting, unless you used info warfare, not a single unit of enemy population remains, and the population of the planet now coincidentally consists of exactly the number of invading soldiers you used who survived the fighting. I dunno about you, but I find this AWFULLY convenient.
Also, to make matters more stark, you are now out a potentially very expensive transport. What did they do with my transport? Obviously, the same thing they did with my colony ships: They took it apart and turned it into luxury condos! Little bastards.
The population figure that you see is the *taxpaying* population. You can look at it this way: When a planet is conquered, the society is thrown into turmoil, industry and jobs are lost, and the citizens are no longer able to pay taxes.
Yeah, but ALL of them? I mean, sure, you might conceivably argue that SOME non-contributing members of society may have survived, but the fact remains that every single member of the LISTED population was accounted for FIGHTING TO THE DEATH. How many non-taxpayers could there possibly be, anyway? Those people just GOT here this last turn!
If you are playing as the Korath, and want to picture them gleefully going about a slaughterfest, then that is up to you.
Pssh. Korath don't invade planets, they just spore them and move in. Everyone knows that! Why waste a perfectly good transport when you could just use a much cheaper sporeship and use the transport to land your perfectly good, unkilled population?
