Yeah, there is a lot that would be involved in adding pregnancy to this game, but the devs could add a very unfinished version if they wanted, I just haven't seen them say anything about it on the discord other than that it is definitely planned to be implemented. That all said, they have stated that they want to get more content in the game so that it is a little less sandboxy and there's actually something to do, since people keep complaining about there not being anything to do but grind, because a lot of people don't seem to understand that 0.2.7 isn't anywhere close to a complete game, lol. Anyway, point being, they may actually be planning to implement pregnancy just to get it in the game, and then as they expand the scope of the story, add more consequences to getting pregnant.
