Religions and books
Honestly, the next update they should up the religion sections up a bit, it's boring, they should add a lot of options like sects insde the same religion, and also a holy book the people of the sect/s follow, and there should be options to make it a cult or make the country rule by what the book has, now I don't know about coming and I think this is impossible.
And for the books, they should make even the normal people write books from time to time, like imagine you name someone Socrates and he makes a book, it would make good lore.
Anyways it's probably impossible in code
