Stuff I would recommend... · 2:35am Jun 28th, 2012
Largely a response to a question from borsko, here are a few of my top recommendations in case the list of 100+ favorite stories on my user page is a bit much.
The Best Night Ever is one of my favorites. It is a very fun Blueblood redemption fic written in the style of Groundhog Day, and has an in-progress sequel that is quite good though very politics heavy and is more of a Rarity fic than a Blueblood fic.
The Flight of the Alicorn is another great one, an in-progress adventure story involving Rarity and Blueblood. Odd, you'd think that was one of my favorite ships or something... 
On a Cross and Arrow is one of the original rule 63 fics in the fandom, and from what I understand is where the colt mane 6 names like Dusk Shine and Elusive come from. Also has an in-progress sequel.
The Ambassador's Son (contains a pony shaped dragon), Wild Sky Yonder (a great in-progress Spitfire story), My Choices: A Twisted Tales Through Time (in-progress time travel/alternate timeline story starring adult Twilight and adorable filly Twilight and Trixie), and Wild, Sweet & Cool (fun and hilarious Dash and Twilight friendshipping) are a few other longer stories well worth reading. Background Pony as well, in case you want something with 20,000+ word chapters.
Tiny Wings and Shine are a pair of Scootaloo and Dash stories, the later of which is written by The Descendant who is just about my favorite author in the fandom, I would recommend anything of his.
Naked Singularity and For the Love of Science are a couple of absolutely hilarious stories by the always fantastic Cold in Gardez. I would also recommend anything he has written.
Two Peas In A Pod in case you want to die of laughter.
Last for now, I think, Sunny Skies All Day Long is probably my favorite "I wish they would just turn this into an episode" story.
Hope this helps!
It helps thanks. Though I personally cannot stand Rarity in the Flight of the Alicorn.
