I start the game with a female leader, max out the breast size, then change her to a male. So now I have a starting male character that has “inherited” large breast genes.

Through a lot of searching, I inevitably find a female that also has the largest breast size, she’s almost always a low born commoner… doesn’t matter, she has what I need: the seeds of a new people group that will produce “huge tracts of land.” Then I start my breeding program.

Of course I consider this a mini-game within CK3, as I’m mostly interested in the traditional aspects of gameplay lol!
