Not really sure how its alot of work, Kate pregnacy basically just a few line dialog when she pregnant and nursing , and few still picture of her pregnat and I believe only 1 new animation with Thomas.NO. IT'S DAMN BAD. It's a damn lot of work for almost no damn content.
All the heavy lifting of the orphanage building is already there , and the script of pregnancy already made.
It just make the game more believable when the women whoring around and beging to get shoot inside all the time.
