Some of my all-time favorites are not for this Board (I got super into the Saw franchise while I was away from the Board, which has a very active fandom and quite a lot of goodfic, surprisingly, but it doesn't exactly strike me as something my fellow Boarders would be into). I have a few from older fandoms that are still very dear to me, though, and which I'd love to share here.

• Three Stories, written by Gimli son of Glóin on occasion of his imminent passing: One of my Big Favorites. This is a short, bittersweet and beautiful Gimli/Legolas fic that rips my heart out every time and then makes me cry happy tears at the end :')
• downbeat: Kylux orchestra AU where Hux is an uptight conductor, and Kylo Ren is an insufferable but insanely talented piano soloist. I have conflicting opinions on the Star Wars sequel trilogy and was never very active in the fandom to begin with, but I love, love, love this fic.
• The Student Prince: One of the classics of the Merlin fandom, and for good reason.
• Particular Peculiarity: My favorite Sherlock Holmes/John Watson fic. (Classic Holmes, not the BBC series, which I absolutely loathe.)
• Veritas: I also have conflicting opinions on the Star Trek reboot movies (for the most part, I don't really like them), but this fanfic is epic and stays truer to the spirit of Trek in more ways than the first two reboot movies did.
• Aeneas, Orpheus, Pollux: A Coriolanus fanfic written in iambic pentameter. Yes, really. And a damn good one, too.
• And, as a member of the PPC (even if not a very active one now), I'd be neglecting my duties if I didn't mention my favorite spinoff works: Ring Child and Blood Raining Night by Neshomeh and Tungsten Monk, which have given me many moments of mirth and are still the spinoffs I like revisiting the most. :)

It was about a wearet named Kew-Kew and followed him and a few other’s adventures. It was quite possibly one of the funniest ones I’ve ever read. It’s on fanfiction.net under the Redwall tag so if you want to go poking around, it’s there.

A couple of years back I solidly would've said Harry is a Dragon, and That's Okay, a fic I enjoyed so much I wrote a 'mission' into it that was really more of a spotlight of 'hey, this joke premise is actually good' turned into an in-universe Intel miscommunication. I think it's a contender for the best mission I've written. The fic itself is really just 'Harry Potter becomes a dragon for no apparent reason,' simple as that, but the author manages to get so much mileage out of the premise. The only nitpicks I really have about it in hindsight are that it starts to drag a little near the end and it has an incredible length of a 3/4 million words, but it's still quite good, and I'm sure the length appeals to others more than me.

Recently, though, I finally found another that might have taken its throne for me: On the Fringes, an XCOM fic about a human and Viper trying to survive the aftermath of the War for Liberation (XCOM 2's canon events). It's honestly so much better than I was expecting going into it, but fair warning that it is a romance fic, so it dips solidly into the NSFW for a single chapter. It's a solid, novel-length story, despite it being, well, human-on-giant-alien-snake-with-arms romance, and I can definitely see why it's the highest-kudos XCOM fanfic on Ao3. Honestly, if I knew nothing about XCOM, it does such a good time introducing the setting and world that I could probably mistake it for an actual published book (complimentary). Who knows, if time works out right on my end, I might find a way to give it some relevancy in my upcoming ESAS spinoff...
