We've always been here, this remake attracted the preg fetish fans since the beginning. The amount of dialogue in the remake that hints towards pregnancy for every character has already been in the game for years. I don't know if you've ever done a 'no birth control' playthrough but when when you do both Morty and Morticia turn into "pregnancy weirdos" as you would call it. The reason all the pregnancy fans are speaking out now is because for them the climax is building up and then they are blueballed at the end, for us seeing the belly is the reward.
I personally haven't spoken out yet because I'm patient, if NightMirror doesn't get the motivation to add the epilogue until hypothetically lets say 3 years from now, I'm okay with that. One of my favorite games back in the day used to be Summertime Saga and the last time I played it was the Eve update. The next update was for the main story and I had no interest, I said to myself "I'll wait until the next update for Ronda". Back then every update had a 6 month dev cycle and I was used to that, so I thought I was making myself a 1 year long promise. Then the main story update got separated into 3 parts, after that the infamous Tech Update began. The Eve update was in October of 2019, my promise to myself was supposed to be 1 year long, and to this day I have not played SS since then. Honestly I don't know why I'm keeping this promise to myself, maybe it's for the principle or maybe it's just been so long I just don't give a shit anymore for how long something takes, but I'll wait because it's all I can do.
So whenever NightMirror does want to finish the project with the epilogue, I'll be there waiting patiently. The man has done a great job so far and deserves a break.
