Fanfic recommendations? Here we go:
Invalid Link Removed (Pen Stroke & Batty Gloom) - infamous, but actually quite good. A classic.
Invalid Link Removed (Jetfire) - Epic adventure fic. One of the classics.
Invalid Link Removed (Ciroton) and its sequel, Invalid Link Removed - One of my top favorite fics. A must read.
Invalid Link Removed (Stonershy) - Definitely one of my favorite fics. Read it. Now. NOW!
Invalid Link Removed (shortskirtsandexplosions) - This one takes the top spot. Longfic is really, really long, but worth every minute of reading. As far as fanfics go, EoP is perfection. I can't recommend this one enough.
Sisters (bassofthe) - Shameless self plug. Princest clop, if you're into that sort of thing. PM for link.
Invalid Link Removed (midnightshadow) and its upcoming sequels - Another top pick. I have a particular fondness for this one. Must read.
Invalid Link Removed (That 1 Guy) - It's not that long yet, but it shows promise.
Wheller's massive series. I mean, really, this stuff is HUGE. Here is his Invalid Link Removed. Highly recommended.
Invalid Link Removed (Varanus) - Perfection. Known for taking very long between updates, but well worth the wait.
Invalid Link Removed (Municipal Engines) - I really love this one.
Invalid Link Removed (ImJustAnotherBrony) - An interesting read. Well written.
Invalid Link Removed (Wanderer D) - Pretty epic. Highly recommended reading.
Invalid Link Removed (Conner Cogwork) and its sequel, Invalid Link Removed - Another classic.
Invalid Link Removed (Corejo) - Yet another great fic.
Invalid Link Removed (Samsara) - A good read.
Invalid Link Removed (Sapidus3) - Great fic, but it hasn't been updated in quite a while.
Invalid Link Removed (GaaruSpike & Beige Monkfish) - A Twilight-becomes-an-alicorn story that actually works
Invalid Link Removed (device heretic) - Read this. Now. One of the best works ever written.
Invalid Link Removed (Daetrin) and its sequel Invalid Link Removed - Interesting stories.
These are only my top picks, I might even have forgotten some. If you want more, just ask, but be specific with what you want. I do read quite a bit.
