Video games have existed for over 50 years now. Video games have had as much time to mature as film had had by the early 1940s. And by the early 1940s film had produced numerous mature works of art displaying mastery of the medium that are still avidly watched and viewed as masterpieces today. The excuse that video games are a young medium may have held 20 years ago in the PS2 era, but it does not hold any longer.
How many movies does your avg movie goer know or can name movies from the 40s? Maybe, maybe half a dozen (it's a wonderful life, casablanca, citizen kane, Disney Fantasia and Pinocchio, and his girl Friday.

Video games are in a weird place because they arguably reached maturity of design with 1985’s Super Mario Bros. But as wonderful as SMB is, it doesn’t mean anything or have anything to say: it is just the first game to truly nail 2d platformer mechanics to a transcendent degree. Indeed, as the OP mentioned, the best video games seem to be able to do as of yet with respect to depth of meaning is the equivalent of a mid-grade zombie film (The Last of Us), and the industry is such a grind that the writers burn out before really developing their craft. Maybe video games will eventually bring a depth of meaning and insight equivalent to their refinement of play mechanics, but they’re not there yet.
