I didn't stop at that sentence, but I can understand the latter sentiment. Zork was a revolutionary game, Fortnite is a cartoon shooter. Other than both games being popular there is simply no comparison between the two in my mind.
Article author here. I get why people trip over that comparison. Unfortunately it wasn't added by myself, nor part of the original draft. The comparison is (somewhat) obviously intended to make it clear that it was a super-popular game.
That said, I'm glad that people like the rest of the article :)
Also not the OP, but the OP is probably talking about its popularity and novelty.
Also, Zork wasn't easy to put down and pick up later.
I was also multi-player in a different way. Instead of being competitive multi-player, it was cooperative multi-player, as in you had friends over and you'd solve it together.
