I would literally pay like 30-60 dollars for an "Army of Babies" expansion/DLC. Where haramase sim style "the birth rates are declining so low you get paid to have as many babies as possible" scenario happens. Or hell, not even paid. I'll still happily still do the work grind but it feels like such a major disservice to the girl to knock them up without the intent to marry them so I'm not going around knocking them up left and right. Remove the guilt so we can "go for a high score".
And if you feel weird about taking from harasim's idea, they not only took assets from other games but also let their game rot for the last ten years without turning it into a legitimate, sellable product. So maybe they can f--k themselves?
