I think the updates will be increasingly complex as the game develops, due to the different impacts of the discisions big and small, relations with each family member and so on. However so far this VN feels the most complex out of all the ones I've had the chance to try actually
Bigger games like this have an update cycle of 2ish month, depends on how many people are in the crew.
Melody, Become a Rockstar are similarly complex as well, however the main/support cast is just a friction of what you can see here! Also writing a story from a female protagonist's perspective is a bit more difficult in my opinion (at least if you dont want to make a slut character, in which case it would be simple) due to our perception on how the genders work on a basic level.
