Games are an art form, completely on par with books, paintings, or movies. I'd say they are one of the most important art forms of our times.
The writing is often so terrible... I wish I could think of a single video game that touched me like The Brothers Karamazov or Les Miserables.
For me, Firewatch was a stunning call to action about avoiding the problems in your life. Beyond direct narrative, there is the silent story seen in games that is rarely seen in books. The implied bits, the attention to detail, the care and love to the craft. For example, there are bits of the Zelda franchise that trends a hair into Jack Kerouac's ending of On The Road. The little moments where you can feel and realize the breath experience of those you interact with, the people you save and those who save you. In that moment you can feel that book-like internal narrative defining all that could have been or might have been. Zelda Wind Waker is exceptionally notable in this space. Majora's Mask defined it.
But masterpieces are few. For each cartridge full of second-rate mindless 8-bit games there is a pack of books by Barbara Cartland, or whatnot.
This is also true of the vast majority of books ever written.
However one could already say that they are the most innovative (and interesting) art form these days.
Check out The Longing, Wanderlust: Travel Stories or Firewatch for recent emotionally deep games.
I played these games at friends' houses back then and didn't see the appeal. Games like Need for Speed, Mortal Kombat or Goldeneye 007 felt more real, less 'kiddie' oriented. But these games aren't really spoken of much these days, while Nintendo originals definitely are.
Need For Speed is considered to be in decline. Mortal Kombat‘s making was a bit controversial with the whole “make employees watch graphic executions to nail the art”, now that in 2021 the focus is less on kids watching violence and more about not abusing employees. https://www.nintendolife.com/news/2019/05/one_mortal_kombat_...
Mario more or less has inspired the same kind of nice fuzzy feeling and polish that is the series’ mainstay. Breath of the Wild reimagined Zelda into an explorable open world to rave reviews.
