In real life or the game? In game it is handy to imprison the rug rats that did not get the correct traits you are aiming for. So you can behead them or starve them to death or torture them.. CK3 is basically a dark age breeding simulator. You are making a family tree shooting for a goal that is your own. If you want to make a Wiccan female pope that is an inbred one armed midget, you can do it. A whole country of gay viking giant beautiful men, doable.. Might take weeks to figure out how though.

@RealisticEyes Interesting. Human engineering. Sounds rather Nazi-ish. I was actually referring to the real life situation... but at 25 not very young anymore.

@EyesThatSmile Unfortunately,.the eugenics the nazis pursued were not unique to Germany of the 40s. It was done in the US too, if to a lesser scale. Forced sterilizations, the Tuskegee syphilis studies, the black stork movie. The list is endless. 1870 to 1940 eugenics was popular around the world. At least the dark ages version of eugenics was more about pairing the people off for certain traits and less about pairing off part's of people. What better concept is there for a game than dark age marriage, religion and breeding simulator? We have made strides as a species but filicide is still illegal (even in texas). We can dream of a better world though.
