Harry Potter: "Resonance" by GreenGecko-- A Snape-adopts-Harry fic, only not just that. Mostly set after Voldemort is defeated, which is nice. Very long, quite good, WIP.
"Mirror of Maybe" by Midnight Blue-- if you haven't read this yet, go now. Harry is sucked into a mirror, lives twenty years in an alternate dimension (sort of), and is returned to his 15-year old body. And that's just the first chapter. My favorite mature!Harry. Long.
"The Best Defense" by JoBishMyoga-- A Yu Yu Hakusho/Harry Potter crossover. One of the best HP crossovers around. The YYH team gets a mission at Hogwarts.
Gundam Wing: Sunhawk-- try both the "Ion Arc" and the "Road Arc." Both are incredibly long, and Duo-centric. The "Ion Arc" is my favorite, but both are great. Written in a series of self-contained stories, which is great. Go to: http://4dw.net/deathndragon/sunhawk.html
Naruto: "Side Effects" by ChibiRisu-chan-- Turns out Naruto's sexy-no-jitsu has a few... consequences. Kakashi and Iruta get in a bit of trouble.
The Sentinel: "The Nature Series" by Francesca-- The TS series that should have been. Very long. Her Due South stuff is also excellent.
Highlander/Stargate: "Changing of the Guard" by Ecolea-- Wow. Puts Methos (and various other immortals) into the SGC. Even if you've never seen either series, check this one out. Very long.
