I'm surprised that no oneelse has brought this up: the "ladies" in this game actually represent concubines. In ancient China, it is not merely a privilage for a king/lord to take many concubines, it is actually a responsibility for him to plant his seed in as many soils as possible. Hence you get VPs for that.

Here in Hong Kong, from time to time we see a TV drama about the rivalry between concubines in the court.
