For some reason i just started wondering how reproduction works for the different species in galciv.
We all know how it works for humans: there are males and females who sexually reproduce through intercourse, with litter size typically being 1 or 2. Pair bonding between parents is common and the parents take care of the children until they are fully matured. A female can produce well over a dozen children over her lifetime, but the actual amount of children depends on cultural and social norms. Child mortality is near 0%. Humans take a long time to reach mating ages and typically wait even longer before they start reproducing.
I imagine Drengin are similar to humans, but with a much more patriarchal societal norms. Females are seen as weak, tools, or possessions. Pair bonding probably occurs but is taboo to talk about in public. I also imagine them having a lot of spartan like norms, discarding defective young, having a "the weak die" approach to growing up, etc. Child mortality is fairly high due to this. Every male is expected to have a lot of sons for honor related reasons and because a lot of drengin die in war. They probably have a bunch of aging and mating ritiuals that involve killing stuff in order to be worthy or manhood/a wife/whatever.
Torians are very different, i see them reproducing like frogs: females lay a couple thousand of eggs, a male comes by and fertilizes them. Still sexual reproduction but without intercourse, though they still have mating rituals and pair bonding. litter size is thousands, but it is accepted and normal that the vast majority die in the first few days after birth, and no real efforts are being made to adress this. However any children that survive birth and manage to leave the nesting area, are taken care of and provided full medical care. During Drengin occupation i imagine every individual egg being grown in a test tube instead of a nest, for higher yields 
Child mortality is extremely high but virtually all of it is in the first few days after birth and by choice. Children grow up quick and family isnt super important to them, due to their fast reproduction families quickly become to large to manage.
Yor presumably dont have genders at all and just reproduce at will/need by coding a personality for a specific function, this is mostly because they are evil, if they were good i would like to think they have more individualism. Child mortalty doesnt exist, children do not need to grow up or be educated, a brand new adult is just popped out of the factory with all the knowledge they need for their function. The limiting factor for their reproduction is the effort required to make new bodies, which presumably is pretty high because they have similar reproduction rates to other races. They evolve/can change by trying out random code changes and picking out the most optimal, but this is all done in simulation so no bodies have to be wasted.
Anybody has any ideas for other races? Or different takes on mine, quite curious what you guys think about how the Yor go about it. Think there are any with more then 2 genders?
