Revising my list of BtVS/SG1 crossover story faves and recs
* * * * * * *
Warning: These are my own notes, made for the purpose of reminding myself what I've read and particularly enjoyed in the way of Stargate/Buffy crossover fics, so there may well be MINOR (for the most part . . . I hope!) SPOILERS contained in just SOME of the descriptions below. So, I'd advise you to skip reading the descriptions and just click on the links to check the stories out for yourself, if you're extremely concerned about plot or relationship spoilers. Otherwise, please enjoy this very incomplete listing of some of the stories I've enjoyed reading and re-reading over the years!
See also my list of SG1 crossover fics UNRELATED to BtVS, as well as the list of BtVS crossover fanfic faves UNRELATED to SG1 for all other BtVS crossovers, and list of favorite crossover fics unrelated to BtVS or SG1.
LARGE FONT indicates stories I've re-read and enjoyed multiple times.

Buffy the Vampire Slayer crossover fics not on TtH:
SGA -- SINEYA'S WORLD by Sarhea (Teyla's team encounters a world unlike any other in the Pegasus Galaxy, populated mostly by very strong women descended from exiles from Sunnydale in another dimension; eventual Sheppard/Willow): https://www.fanfiction.net/s/8169799/1/Sineya-s-World (or http://archiveofourown.org/works/428748/chapters/722921).
-- WEIRDNESS IS GENETIC by Sherza (WIP, but nearly finished; during the summer after BtVS season 1 Xander discovers that Jim Ellison from Cascade is his real father, then Xander's spirit animal leads him to a newly awakened Sentinel in Colorado Springs, Clone!Jack, for whom he's meant to be the Guide; Season 2 of BtVS starts out much more promisingly, with Sentinel Jon and Guide Xander added to the Sunnydale defense forces, along with a much better trained Buffy, Willow, and Giles, thanks to Jim and Blair): http://www.fanfiction.net/s/8050648/1/Weirdness-Is-Genetic (or http://www.tthfanfic.org/Story-25468/Sherza+Weirdness+Is+Genetic.htm)
-- GROWING PAINS series by Wren10514 (clone!Jack/Dawn -- 1st story is straight SG1 fic, but there are 3 sequels so far with Dawn and Oz added to the mix; EXCELLENT!):
1) http://www.fanfiction.net/s/4978831/1/Growing_Pains (1 chapter. Jon O'Neill and Cassie deal with a Goa'uld problem at the high school)
2) http://www.fanfiction.net/s/5079618/1/Growing_Pains_2_Dawn_cometh (4 chapters. With Oz as back-up, Dawn is sent to infiltrate Colorado Springs High, where Willow's sure there's at least one case of possession by a 'Guld' demon. Sparks fly between Dawn and Jon.)
3) http://www.fanfiction.net/s/5176517/1/Growing_Pains_3_Happy_Birthday_Jon_ONeill (1 chapter. One year after he was created, Jon's DNA starts to break down again and his friends -- both old and new -- rally in support; also, Thor is introduced to 'metaphysical energy 101' by Dawn.)
4) http://www.fanfiction.net/s/7091223/1/Growing_Pains_3_Werewolf_Attack (1 chapter. Jon and Dawn's first date is interrupted by blood and death, which should surprise absolutely no one.)
-- ENCOUNTERS series by Elemnestra Aethelflaeda (Jon O'Neill and Cassie Fraiser have formed their own group of alien-fighting High School friends, leading to interesting encounters and near-encounters when the Scoobies settle in Colorado Springs for a while and wonder how ordinary kids got so practiced at fighting demons when there's no Hellmouth around):
1) http://www.fanfiction.net/s/6649532/1/Indirect-Encounters (1 chapter. Running late for a demon-slaying, Buffy, Willow and Xander observe from a distance while Jon and friends expertly dispatch a tree-demon that attacks their school field trip)
2) http://www.fanfiction.net/s/7925607/1/Near-Miss-Encounters (1 long chapter. An alien/demon incursion at the local mall results in a deepening of the mystery of Colorado Springs for Buffy and Xander, who are too late to witness Jon and company deal with the situation, this time; Jon turns out to have far more access to the power of his Ancient genes than original Jack usually displayed)
-- IN THE GENES by AlecStar (Sam Carter has a 'dumb idea' that could save the Asgard, but she needs to find a woman named Buffy Summers in order to do it, and the Scoobies are Not Amused): http://www.booksandtales.com/fanfiction/itgindex.php [also at TtH: http://www.tthfanfic.org/Story-7930/AlecStar+In+the+Genes.htm; also on ff.net: http://www.fanfiction.net/s/2645891/1/In-the-Genes]

-- ALL OVER THE PLACE by Burmafrdnow (Cassie's Calling as one of the new Slayers has SG1 up in protective arms and butting heads with Riley Finn and others 'in the know'; author needs much more proof-reading, but well worth reading anyway): http://www.tthfanfic.org/Story-25832/burmafrdnow+All+over+the+Place.htm

-- mostly SGA fic SAVING EARTH...AGAIN by DarkPhoenix (desperately in need of proof-reading, but it has its moments; Buffy is Jack O'Neill's illegitimate daughter and becomes John Sheppard's significant other, while doing the usual world-saving thing): http://www.tthfanfic.org/Story-15739/DarkPhoenix+Saving+Earth+again.htm

-- REQUIEM FOR DAWN series by DaveTurner (very sad, but Buffy/Jack at the end): http://www.tthfanfic.org/Series-145
-- A BRANE OF EXTRAORDINARY WOMEN series by DianeCastle (very entertaining multi-cross multi-'verse series, crossing and recombining the heroes and villains of HP, BtVS, SG1, Batman, The Secret Life of Alex Mack, and even the original Bionic Woman, with a surprisingly addictive and extra-lengthy third installment that has led to a wealth of spin-off fanfics itself): http://www.tthfanfic.org/Series-2585
-- XANDER AND YET ANOTHER DEMON series by DianeCastle (very entertaining! Xander/Anise/Freya): http://www.tthfanfic.org/Series-2591

-- SHE MEANT EVERYWHERE! by JoeB (Potentials are activated throughout the galaxy, so Buffy et al try to help the SGC help the new Slayers; not quite finished, but Burmafrd/Burmafrdnow has written a very satisfying coda on fanfiction.net, Gods and the Champions They Like, so can be read as complete, in a sense: http://www.tthfanfic.org/Story-4485-11/JoeB+She+MEANT+Everywhere.htm

-- A HACKING GOOD TIME by Kei (humorous one-shot: Willow the hacker saves the world): http://www.tthfanfic.org/Story-4965/Kei+A+Hacking+Good+Time.htm

-- MAGICAL CAGE series by litgal (only the two-chapter humorous sequel set in Sunnydale is slightly Spike/Xander slashy at times, and the main story is also quite good . . . if in need of more proof-reading): http://www.tthfanfic.org/Series-425 or http://litgal.brinkster.net/MagicalCage/1.htm
-- AIRMAN HARRIS by litgal (sweet Xander/Daniel slash, but also offers a very insightful and hopeful alternate version of the last half of BtVS season 5, with some great moments of Buffy learning from and impressing the heck out of Jack, as one commanding officer to another, and Xander getting some pretty good PTSD counseling): http://www.tthfanfic.org/Story-27088/litgal+Airman+Harris.htm or http://litgal.brinkster.net/Airman%20Harris/Harris.htm

I hope!) SPOILERS contained in just SOME of the descriptions below. So, I'd advise you to skip reading the descriptions and just click on the links to check the stories out for yourself, if you're extremely concerned about plot or relationship spoilers.
