Oh for [censored] sake. Why should they? This is the story they thought appropriate for Fallout 4, this is what we get. Your character has to be a husband/wife and a daddy/mommy. It may not click in with people who aren't married or those that are but never had a baby, it won't click in with heterosixuals, homosixuals, zoophiliacs et cetera. But this is how it is. So why do they need to write a story YOU want? What makes you so damn entitled?
