Almost all or all dolls will get pregnant. But in the enlarged belly there will be not a child inside, but reserves of nutrients for milk production.Sorry for targeting an old comment, but since you seem interested in feedback I wanted to bring this up. I find it disappointing that this is the plan; mainly because I remember dialogue that specifically mentioned the doll's reason for injecting the last humans with MilkoGEN and SpermoGEN. IIRC, it was part of a standard protocol to repopulate and prevent endangered species from going extinct upon encountering them. I haven't gone back through the game recently to see if it was removed.
If the dialogue was removed, then I'm sorry to hear that decision was made from a development direction standpoint.
If the dialogue wasn't removed, it probably should be just to avoid the studio's namesake (aka fetish blue balls).
Either way, I enjoyed that premise and I wish it would've been explored.
Edit: After reading some more of the thread, that's probably the reason so many people brought up pregnancy in the first place. Hopefully I'm not imagining things.
