All the Horizon Fanfic Stats You Never Knew You Needed
So I did some data analysis. More graphs and lots of rambling below the cut.
I love graphs. And spreadsheets. And making my hobbies unnecessarily complicated. So obviously once I discovered that there's an unofficial ao3 api, I had to learn a new programming language so I could throw some math at my Horizon hyperfixation and make some graphs about fanfics. This post is the result of that rabbit hole, I hope you enjoy it!
Before we get started, I want to make one thing explicitly clear: this post is a celebration. It's a celebration of fanfic, authors, and the fandom in general. If you have something mean to say about a ship, a writer, or a fic, this ain't the place. I made these graphs and wrote this post as a love letter to a game I'm obsessed with and the incredible people who make the fan content that is my main form of sustenance these days lol, so let's keep the discussion positive.
One last thing: I generated these graphs from data that I pulled on Aug 4, 2022. Anything published after that won't be reflected here. Alright, here we go! Let's see some graphs!
Fanfic by Length
The first thing I wondered is what the average length of fic was. I did not include any fics below 100 words, assuming they were either art or placeholders, neither of which provide any useful information regarding number of words.
I defined the categories as follows:
Ficlet - less than 2000 words
Short Story - 2K-10K words
Novella - 10K-50K words
Novel - 50K-100K works
Behemoth (pun fully intended) - 100K+ words
Obviously, there's some blurriness at the category edges, but it's pretty clear most fics tend to be relatively short. I'm genuinely surprised by how many huge, sprawling works there are though - I definitely expected there to be a single-digit number of behemoth fics. Mad props to the folks writing those monstrosities for the rest of us to enjoy!
Fanfic by # of Chapters
This graph kind of underscores the point about most fics being relatively short. There are almost twice as many single chapter fics than all other fics put together.
A thing I think is relatively unique to fanfic as a medium though, is that a fair number of those single chapter fics are novella or even novel length. You're not often going to find a book at a bookstore that's tens of thousands of words and has no chapter divisions, but that's not unusual in fanfic.
Fanfic by Author
Okay, the first thing you need to understand about this graph is the following numbers:
1
2.6
Those are the median and mean fics published per author in the Horizon fandom, respectively. In case you slept through your stats class, what that means is most fanfic writers have written one or two Horizon fanfics. Now go back and look at the graph.
...yeah. We as fanfic lovers owe a lot to these folks. Most of them are on tumblr, so even if you don't have an ao3 account (same, babe, same) you have no excuse not to go show them some love!

Fanfic by Rating
Okay, now things are getting spicy! First of all, if I'd had to guess the most popular rating, it probably wouldn't have been Teen. But, given how popular the "fluff" tag is (foreshadowing for the tag graph later in this post), I guess it shouldn't be that surprising.
Secondly, I'm clearly not the only one who struggles to understand what exactly the Mature rating is for, considering it's the least-used rating by a fair margin.
Fanfic by Ship
The most popular ships, colour-coded based on orientation. From left to right: mlm, straight, wlw, poly, machines(?????), unknown
I want to reiterate here that I made this post to celebrate the awesome Horizon fandom, so if you're thinking of using this graph to argue that one ship is better/more correct than another... just don't, k? Good.
I also combined similar tags, so if someone used all three of the tags "Aloy/Erend", "Aloy/Erend (Horizon: Zero Dawn)", and "Aloy (Horizon: Zero Dawn)/Erend (Horizon: Zero Dawn)" for the same fic, that's actually going to count as three fics in the Aloy/Erend column. I'll probably end up redoing this graph eventually with a less naive counting algorithm, but for now this is what we've got.
Now that we've got methodology out of the way, let's talk about some cool things this graph shows!
First, Kotaloy shippers obviously have a lot of things to say. Unlike the other five most popular ships, Aloy/Kotallo is the only one involving a character that wasn't in the first game. And it's the second most popular ship! Y'all are rabid and I love it.
Second, of the wlw ships, the second and third most popular ships involve a character from the DLC and a character who dies immediately after you meet her, respectively. You guys are out here making meals from crumbs and I am impressed. Also, though, why don't Petra and Vanasha get more love??? I'm unsurprised that Talanah and her favourite Thrush are the #1 ship, but I (a clueless straight, to be fair) loved both Petra and Vanasha and definitely expected to see more fic involving them.
Third, I love the variety here. This graph only includes ships with at least 10 fics, and there are so many different ships represented! There were tons more that had 5-10 fics too, and it honestly made me so happy to see that there were multiple fic options for almost any pairing in the game.
Fanfic by Tag
Y'all. Look at all the fluff. People always joke about making their blorbos go through it in their fanfic, but like. There is SO MUCH FLUFF. We all really just looked at these characters and went "well, they deserve nice things for a change", huh? I also love how popular canon divergence is - anecdotally, I usually see that tag on fics that are like "well, what if that shitty thing didn't happen?"
That's not to say it's all sunshine and rainbows. The next two most popular tropes are "angst" and "hurt/comfort", and as an enthusiastic consumer of both, I'm not surprised. But again, anecdotally I see a fair number of fics tagged with one or both of those and a "fluff" tag.
Going back to the ratings graph, where we learned that the most popular fic rating is Teen & Up, it shouldn't be surprising that both "First Kiss" and "First Time" are more popular tags than any of the more explicit sex ones. Also, given that Aloy grew up an outcast, I think the popularity of those tags speaks to how fun it is for both writers and readers to delve into what that means for her when it comes to sex and relationships.
Finally, the most-used content warning tags will surprise exactly no one, I think. Canon-typical violence (because duh), PTSD (growing up a literal outcast before finding out you're a clone made by an AI so you can save the entire world from extinction will do that to ya, not to mention all the shit Aloy's friends/lovers have been through in their own lives), and canonical character death (glares at GEMINI) are all pretty obvious choices.
Conclusion
Because I have zero impulse control, I'm already working on a part two for this post, where I will address such pressing questions as "Which ship has the most verbose authors?" and "Who's the gayest Horizon character?" as well as recklessly use the powers vested in me by the math and algorithm gods to find some hidden gem fics that you might not have read yet.
In the meantime, I would love to hear some more opinions on these graphs! I've commented on some of the things I found interesting, but there's lots more to address here, so feel free to reblog this post or snag any graph you find interesting to use in a post of your own. I only ask that you tag me if you do - because I want to read what you have to say!!
Also, if there's any stats or questions about Horizon fanfic that you're particularly curious about, let me know. I'm limited by the information available on ao3, but I will do my best to find you answers and include them in the next post.
Lastly, one final reminder that we're here to celebrate the awesomeness of Horizon fanfic, the fanfic authors, and the fandom in general. I will humbly accept all constructive criticism about my (somewhat questionable) statistical methods and data interpretation, but ask that you keep comments about ships, tags, authors, etc positive and productive. Remember these are real people creating free content for the rest of us, and don't yuck someone else's yum.
Thank you for reading, and I hope you found this half as interesting as I did!
