Hopefully GC decides to actually implement pregnancy at some point instead of fucking around with AI chats. We've got a menstruation cycle now which is a solid first step but now we need the actual pregnancy itself and childbirth to really make all this work. Child characters would probably need to be added as well cuz it'd be hella weird if characters just gave birth to 18 year olds... Not sure if this would violate any sort of Patreon rule or something (even tho there'd be no sexual content for minors) but it would definitely add a ton of immersion. If the children would actually be a mix between the two parents appearance wise, it'd be perfect.
GC really has the chance to make this game very special and potentially even turn it into one of the best life-sims out there + it has 2D art which is even rarer for this kind of game.
