Is there any reason as to why the preg variables are not turned on when accepting the rachel/jamie talk opportunity?
I rejected fucking rachel in beginning of game to stay loyal to jamie, I accepted the pregnancy opportunity when rachel and jamie talked about it with mc after harem was established but preg variables are still off in game. Going by that logic it would be impossible for jamie or anyone else to get pregnant.
Realistically, he probably hadn't thought that far ahead and to how branches ideally increase exponentially with each new love interest. New characters can be added or avoided (2 branches), and then impregnated or not (2 branches off the added branch). So that's 3 branches per LI, not including how it works into the story tree for all the other LIs.
Another harem game dev initially had pregnancy points tracked per LI in a stat screen (min: 0, max: 3, +1 per creampie). Latest updates just automatically creampie everyone repeatedly because ostensibly he couldn't figure out how to handle all those variable branches and decided to just force everyone to max capacity so there's just one result to deal with.
Hindsight is 20/20. For Braindrop, Foresight is just a nifty potential name for a new character.
