More fetuses at once the better for me. As far as a gameplay mechanic Haremase Simulator has the right idea, it's setting is "woman to man ratio 20:1 for reasons" so the MC gets paid by the government to get women pregnant. Having a reason why the MC gets money for making babies is probably the easiest way to have a pregnancy focused game. Seeds of Destiny has the characters pregnant with giant seeds so they can appear pregnant without dealing with babies. I suppose a really corruption focused game could do something with abortions or infanticide, that wouldn't be for me though.
