Oh man, THIS is way tougher than the first. Not because I don't like reccing, because I do, but because narrowing it down is tough. And I'm so biased towards my tiny fandoms and my friends (though argumentatively I only spend time following good writers.
Then there's the reccing small/underappreciated, which automatically disqualifies rec staples like the Inception Mental Ward AU and the X-Men:FC with Azazel having his dirty way with Charles and probably most of Rio/Quo's writing.
Dark City - Control by kurushi. Every experiment needs a control group. But The City is a very complex experiment, and it needs complex controls to succeed.
Gorgeous, innovative piece going into the background of the city and everything involved in the city itself, told through the eyes of several members of different control group members. And Daniel. Genfic, but I've still got my slash goggles on and it played into my OTP nicely. <3 I still re-read this, the world building in it really impressed.
Flatliners - Triptychon (Dave/Nelson) by Rotaryshakes. A short piece showing how each of the characters find out about Dave and Nelson. It's one of the few things where I didn't hate Rachel. (I still can't use the word "like"... fucking Julia Roberts. But it's close.)
Dark City - Theorem by Chibi-Kaz. "Not all of the Strangers were so ominous." I love seeing minor character pieces because
And finally, recs for my obscure loves: Crossovers. The crackier, the better. XD
24/Eleventh Hour - Nuit Blanche (Jack Bauer, Jacob Hood) by speak_me_fair Randomness. Jack's brain. Coffee. Putting Things In Mouths. Bacterial Testing. Slashy Thoughts. Hands. This is the worst night of Jack's life...
Dark City/Stargate Atlantis/Iron Man/Bones/Numb3rs/NCIS/Eleventh Hour - Bull Session by bonnie131313. I really want to rec her whole universe, and at some point will sit down and link it all chronologically. There's something so adorably crackfilled yet perfect about the idea of seven geniuses as teenagers attending summer camp together and getting into various misadventures. The characters are great and the interactions are hilarious. Later on the series gets gut-clenchingly angsty and ends beautifully sweet. Love it.
