Uncharted 4 and the grief of finishing a great video game

When my son was coming to the end of Harry Potter and the Deathly Hallows, having avidly consumed the previous six books in the series, his progress noticeably slowed. He'd go days, weeks even, before finishing a chapter – so much so that we thought that he was going off the story altogether. He was drawing it out. Like millions of other fans, he simply could not face leaving Hogwarts. Harry, Ron and Hermione had become more than characters: they were friends.
