I'm conflicted. On the one hand I like preg stuff but on the other this game is completely thematically and technically divorced from it. Its not fit to be a preg game, there's no magic in its lore (at least none that cant be passed off for hallucinations) so you can't magically speed pregnancy up and game's speed where each click takes usually only a few minutes makes 9 months take forever. I think I never even managed to reach that long into the game. Also kids will be just a number without any effect on the game, like in most hastily slapped together preg systems, which is kinda too much on my disbelief suspension.
A lot of stuff surrounding pregnancy and offspring which is explicitly underage also often brings restrictions to the brutality of content. It would be nice if Bailey gave you a choice between paying for upkeep of your child or feeding it to sewer lizards, or drowning it in the sea or selling it for organs or something, but I fear that what will eventually happen is that all those evil-ish acquaintances who currently bully, beat and blackmail protagonist will turn all lovey dovey in future updates to accommodate pregnancy content and those random rapists will make you sign consent forms and provide documents that MC is at least 18 before attempting to rape.
1) I think generally speeding up pregnancy would be a good idea. Alternatively just putting it as gameplay option. Similarly how you can customize actual animals vs bestial humanoids.
Have accelerated pregnancy. Bullshit it being gameplay reasons or MC taking ''innovative'' pills that can accelerate pregnancy.
2) My main concern is there too about kids you have via pregnancy being just a number. Instead of actual added characters that are your own despite fortunate or unfortunate circumstances with their... conception.
3) As for content with the offspring you have: Choice is imo simple. Leave the mechanic as number generator for how many kids you have.
Or
Bullshit it. Have multiple ways to age them up. Be it via devil/anglels present in the game. Alternatively, give them innovative and miraculous growing pills. Which turn them later into a person you can fuck or... get fucked according to rule 7 of F95.
While at it, possible education? For example, if they're stuck in a orphanage, you educate them.
Depending on how much time you spend with them and educating them, they get personalities assigned to them.
Based on these personalities, they behave in various ways.
For example, if you treat them right, teach them and spend time with them, they turn out to be good people when they grow up. However, they also grow vulnerable.
Alternatively, if you mistreat them and ignore them... they grow resentful and can even "harm" the MC or attempt to rape them. Because that's what they have been exposed to and seen around without MC's explicit care.
4) I do agree though that events relating to evil deeds directed towards the
adult offspring of the MC would be great. Be it involving them or they doing the evil deeds.
Would add some insane amount of depth.
