An excerpt from the article:
"It had been a long battle for survival, but he managed to stop the imbeciles from defeating him for real."
Thus begins the longest work of fiction ever written.
Nope, it's not Proust's À la recherche du temps perdu (In Search of Lost Time).
It's The Subspace Emissary's Worlds Conquest, and it's a Super Smash Bros. WIP (work-in-progress) on fanfiction.net. As of July, the fic is 3,548,615 words long. That's three times longer than Proust, and six times longer than War and Peace.
You might say that AuraChannelerChris, the author of Subspace Emissary, has a tendency to wax verbose. Their FF.net author profile alone is ten thousand words long. There's even a 60,000 word prequel, itself longer than some novels, that brings the current word-count above 3.6 million. It also has 2,200 reviews (an average of one review every 1,700 words), and its own TV Tropes page.
For reference, Proust's À la recherche du temps perdu is 1.2 million words long. Currently, this fanfic is in its 208th chapter.
I'm quite astonished to say the least.
