"I wouldn’t be surprised if, in 10 or 20 years, video games are creating fictional universes which are every bit as complex as the world of fiction of Dickens or Dostoevsky."
Jay Parini, a writer who teaches English at Middlebury College, from this NYT article about books publishers creating video games to tie into their books.
I doubt that video games will ever replace books, but Parini is right — there’s untapped potential in games, and one day someone will figure out how to exploit them.
