The author of this article seems to believe that 2D graphics cannot be re-used in a game and/or is unaware of the use of tiles, palette-swapping, and other techniques used to make production of 2D games more efficient. Very strange.
It only takes one or two sentences to explain this more accurately, and I think we should all prefer that over saying something that is about 90% wrong but slightly shorter.
I also cringed when the article said that we couldn't really know why the Columbine kids went on a murder spree when other people who played Doom didn't. That is a totally ridiculous thing to say; We know exactly why, and it's because one of them was a bonafide psychopath and the other was clinically depressed. Again, something explainable in a sentence that was misrepresented in the article.
Historians should be more concerned with accuracy than word count.
And spectacle was one of the biggest sellers of games.
