with how much fucking going on in the game, you'd think that someone will get pregnant, but who knows maybe it'l be set in the game later
What would be the game-mechanical point though? What would you get out of it?
Then it should also be equally viable for male and female protagonists, and avoidable if a player really isn't into the kink.
At that point, the mechanic may very well be "whatever", impact-wise, and development time may be better spent elsewhere.
Like curbing the escalation in enemy unit count/power if you own too much of the map, because sheesh that gets ridiculous. On the archipelago map I made the mistake of taking over the merchants early and now I can't conquer any more land because the enemies have equal numbers to my Avatars, but twice the health (also, improving the units' health on level up seems hardly worth it, at least for Avatars... and the global upkeep increase per unit feels overly punishing for using worse units).
Maybe I need to just
wait until I have a higher population, to pay more taxes, but... waiting sucks. Changing taxation policy from low to something higher may work, but it would slow down growth... and because of how each new unit makes
all others more expensive, I wouldn't even get
that many extra units out of it.
Edit: Oh, right, bug report: inviting the incestuous siblings to your room has some issues, at least with a red-headed futa protagonist. One path shows the wrong character penetrating the sister entirely. Also, some pictures are put together wrong once the sister has bigger boobs. ...I think. And unless I missed a fix.
