Do you really want to raise a family in the world I created as it is now?
Pregnancy has been planned to be something that happens after the whole story is complete since I started developing the game.
Actually, yeah, it would not bother me at all to have some babies before e.g. elf freedom is secured. There are all kind of threats and worries in the real world, you know, and waiting until everything is safe isn't an option.
However… I’m less interested in a Family Simulator and more interested in having some of the Harem sporting full bellies and swollen breasts with darkening nipples! It could be a little like Android, where she can set her breasts to a preferred size, or how the girls can wear my chosen outfits. At least for now. And that need not wait for a narrative resolution.
That said, I can of course respect your vision and narrative requirements, disappointing as this is for me as a bit of a pregnancy fetishist!
The implication of that question is that our little team of misfits will actually be able to change the world. Which... I didn't think this was that kind of game?
Dont' get me wrong, I don't disagree with pregnancy being end-game content, but that's because that's the logical end (you and your girls are reasonably dafe and stable, and it's time to think about a family - fin), rather than "we changed the world and now our children are safe".
Yes, I would totally have a child with Lin, right now, and entrust her (or him) to their half-brother or sister, for "safekeeping" once I'm gone. Along with Lin, really, since she is totally going to outlive the MC by several centuries.
No matter what, humans who are currently alive are not going to live more than a short century, so it's worth considering the very long term for our family, and that implies looking beyond the problems of the here and now.
