I imagine a lot of us have heard of Cliff's Notes, those dreary little pamphlets that helpfully summarize plays and novels and poems assigned in English class. They seem to give you a good idea of what's going on in a tough piece of literature without any risk of actually feeling immersed.
"Don't read the Cliff's Notes! You're only ripping yourself off! Teachers will know if you do!" was the adults' battle cry. Oh, plagiarism was bad too. And yes, plagiarism is still bad, but these warnings didn't really teach us how to balance legitimate learning you can't do on your own with our own thoughts, and I think a sadly high percentage of kids knew what the teachers wanted. Stuff that would show the teachers they thought for themselves, because it worked last year for other students they knew.
But I wanted more. I wanted something that would illuminate. It felt greedy. I remember playing some not very good Narnia choice-games on the Apple. Some had minimal dice-rolling. One had an action game at the end that actually required effort to lose. I recognized, even at a young age, what a money-grab it was, but I still wanted more, and later when I found the Asimov archive, I still played the Narnia game I'd missed.
And we have them now. Some are interactive, but some aren't. I remember finding an Internet comic that summarized Ulysses. Obviously, it missed a few finer points, but it helped a lot. I needed the help.
And I think works like AKACF do that, and well. I've read Gawain and the Green Knight--Tolkien's version, at least--but it was so long ago I forgot most of it. And part of me felt uneasy that he was a bit too much of a Good Guy. AKACF gives him the option to behave poorly, replete with nagging noblemen and ladies who tempt him to. It doesn't drag on, but certainly it gives me a feel for the "why not just give in and get on with it" that we sometimes feel before making a bad choice, and yes, that is part of morality. Curiosity for the wrong things is universal, as is saying "Oh, I know what I'm supposed to do, but it seems so boring," and how do we resist that? Yet, even if you act terribly, Gawain never comes off too badly. That'd be too much authorial interpretation. However, when he strays from the path, different things happen than in the original poem, and I think the branches are both fair and interesting. The author is still pretty much faithful to what would've happened, but just asks "what if Gawain gives in a little?"
As for the story: a mysterious green knight appears on Christmas day. He tells King Arthur, hey, cut my head off, but Arthur can't bring himself to. Gawain offers to and does. The price is: within a year and a day, Gawain must find the knight and accept a similar blow. He has no clue where to look. But with time running out, he manages to find a castle where the lord takes him in. The lord's wife attempts to seduce Gawain, and here I'll draw a spoiler veil to mention the choice between behaving better or worse than Gawain is pretty clear. You can even utterly ignore the lady of the castle. The lord knows where the Green Knight is, and yes, Gawain finds him and faces his fate.
Being able to do walk through Gawain's choices leaves me with much more of a feeling than "good guys gonna good-guy," so it was a success on that alone. I largely glossed over the bits that the author put in a content warning for. That's my style in general. At least, the first time. But once I'd gotten through, I appreciated being able to look through things by chapter, again, and even change the critical choices you made in, say, chapter 5 before trying chapter 6. It's nice to be able to lawnmower alternate story lines or pick them off a la carte, and while AKACF is worth re-reading, I'm glad it's very not-thirsty about it all. I've left so many games I meant to look at again because the effort to start up would be too much. While it's obviously nontrivial to draw this up as an author, it gives accessibility without ruining any surprises, so I encourage it. Here, you will probably want to tweak how well Gawain behaves without having to re-pay your dues.
I really wish I'd had this sort of thing for tougher literary works when I was a kid, and I hope other people follow the author's example and make something interactive like this. While gutenberg.org is all well and good for the latest classical work I want to read but never got around to, it seems like there's a lot of fertile ground for other works. In addition, ChoiceScript seems well-suited to changing these options--this is dryly stated, but in a nutshell, this is what happens. And it sounds trivial to write until you sit down and do it and have familiarity with the source text. Still, providing these what-if options seems like an achievable goal for many potentially tricky classical works, and I hope to see more works interpreted in this way, whether for IFComp or general consumption.
