I like mostly crossovers and self-inserts so...
Title:   Nuke 'Em Till They Glow!!
Author:  Benjamin A. Oliver
Location:
www.rakhal.com/florestica...index.html
Status:  10 chapters and ongoing
Source:  Sailor Moon, Ranma 1/2, DragonBall, Monty Python, etc
Comments:A self-insert into Sailor Moon and it is a doozy.  Basically take Sailor Moon 
and add an overly violent, psychotic, explosion-loving Atomic Starlight Knight, more 
Monty Python references than you can shake a dead parrot at, bad puns, crossovers with 
with ranma, robotech, DBZ(level 10 super sayjin?), and an arbyfish.  Shake, stir, frappe 
and leave congealing in the back of the fridge for a couple years and you'll get this 
fic.  It is great, it is funny, it is a good read.
By the same author is Terra in Tokyo...
Essentially a rewrite of NETTG!! 
Incomplete with 10 chapters on the website (though didn't Benjamin Oliver release a chapter 11 on the FFML?)
Title:   Youma Blues
Author:  James Sheldon?
Location:
www.100megsfree4.com/drak...ction.html
Source:  Sailor Moon
Status:  10 chapters and stalled
Comments:Jedite recruits a human.
Title:   Sailor Moon: Omoi
Author:  Strike Fiss
Location:
www.geocities.com/Tokyo/9110/ or 
www.studioshinnyo.com/
Status:  ongoing with two complete books and one ongoing book with prelude and five parts.
Source:  Sailor Moon
Comments:The author's earlier chapters are nothing much, but I've really enjoyed the developed writing of his later chapters.
Title:   Destiny
Author:  Gabriel Blessing
Location:
www.ranmafics.com/Destiny/index.html
Status:  Completed
Source:  Sailor Moon, Ranma 1/2
Comments:Gabriel is very good at writing emotions.  "Destiny" deals with the characters 
having to deal with their own destinies.  And how two different people do it.
Title:   Finishing What You Start
Author:  Gabriel Blessing
Location:
www.ranmafics.com/Finishing/index.html
Status:  Completed with a prologue, 7 chapters, coda, a side story, and a spamfic.
Source:  Sailor Moon, Ranma 1/2
Comments:This is another Sailor Moon/Ranma crossover.  This story, as the title states, 
is about determination to finish what you start. 
Title:   The Dance of Shiva
Author:  John Biles
Location:
www.maison-otaku.net/~rhe...hiva1.html
Status:  Complete with a prelude, 18 regular chapters, and the final chapter/epilogue. 
Comments:An epic mega-crossover with the emphasis on "mega".  But mostly is Bubblegum 
Crisis, Tenchi Muyou, Sailor Moon, Kimagure Orange Road, and Patlabor.  It is beautiful.  Great ending.
Title:   Black Moon Rising
Author:  John Biles
Location:
Status:  Complete
Source:  Dance of Shiva
Comments:A continuation/sequel for "Dance of Shiva" by the same author. 
Title:   On A Clear Day You Can See Forever
Author:  Mark MacKinnon
Location:
www.shadowchronicles.net/
Status:  Ongoing with 20 chapters
Source:  Ranma 1/2, Sailor Moon
Comments:It is a sequel of this author's Cast A Long Shadow.  Where an alternate Ranma, sole survivor of his universe manages to get into an very alternate Sailor Moon-verse.  A bit ecchi seeing how there are apparently few social taboos on sex.
I saw Sailor Nothing being recommended.  If you like that one, there was another along the same lines. 
Title:   Cynic
Author:  Django Wexler
Location:
www.bloodgod.com/writing.asp
Status:  Complete
Source: originial
Comments:Another great dark magical girl story.  And Mr. Wexler is a published fantasy author.
Title:    Sailor Moon: Gray
Author:   Django Wexler
Location:
www.bloodgod.com/writing.asp
Status:  Complete
Source:  Sailor Moon, Unforgiven (whatever that is)
Comments:What do the Sailor Senshi do with their time after they've finished saving the world?
