>>144385Sorry for the wall of text. TLDR: Yes, I think reading Fallout Equestria is worth it. I listed some personal recommendations below to help sift through the garbage on fimfiction and provide a starting point.
It depends on what you are looking for. The FOE fanfiction universe has a lot to offer. The groundwork and world building done in FOE strikes a good balance between incorporating Fallout lore and creating its own original ideas. A common explanation of how it differs from usual crossovers is that it is Ponies IF Fallout not ponies in Fallout. The setting describes Equestria's decent into a nuclear ruin rather than simply assuming it is or placing the characters into such a setting.
A common complaint is that its plot is similar to Fallout sometimes, but I really don't know what people were expecting in a crossover. The story is long, but it reads more like a Fallout play through or a RPG campaign than a single story. Some complain about this, but I feel it makes sense. Nobody plays a Fallout game just to run the main quest and be done. Little Pip (the mane character) meets all kinds of ponies and does all kinds of stuff. The fic isn't perfect. There are somethings inside of it that did not age well. However, I don't hold super high expectations for fanfiction, so little problems here and there don't unnerve me too much. Like some shitbag on the internet is writing highly specific pony crossover fanfiction on the internet for free, its never going to be a magnum opus like Hamlet or anything.
I didn't read the original first, and its kinda fun to have to figure out what's going on when a side fic mentions something from the original. I also didn't know any of my fallout lore until I read FOE so that also made it super fun for me. I've addressed some common criticisms in the above paragraph, but don't let that deter you. FOE is great stuff and I really enjoyed my first time reading FOE and its various sidefics. If you want to try some FOE, but don't want to go into the long ass original first, I'll link some good side fics down below.
https://www.fimfiction.net/story/119190/fallout-equestria ← Original by the 9/11 obsessed meme man himself KKat. Its good, but shows its flaws at times.
https://www.fimfiction.net/story/208056/fallout-equestria---project-horizons ← By Absolute Madman Somber himself. Longer than Fallout:Equestria, Project Horizons follows a Security pony named Blackjack and is gritter and more sexual that FoE ever was. Starts out great and slowly turns into an insane ride akin to an edgy anime or final fantasy game. Infinite self hate, PTSD, and death. I enjoyed it but the final arcs were really out there. Got my normie friend to read it, and he got some girl he knew to read it so it stands to reason people like crazy. AUTISM WARNING: READ AT OWN RISK
https://www.fimfiction.net/story/7812/fallout-equestria-guise-of-chaos ← Former Raider wakes up from a comma to find himself forgetting everything. Like Jason Borune, but instead of government black ops, sadistic raider past is trying to catch up with him. I liked this one a lot and it wasn't as long as FoE. Gritty, but not insane batshit crazy like Project Horizons.
https://www.fimfiction.net/story/931/fallout-equestria-pink-eyes ← Pink Eyes is the closest I can recommend to a heartfelt fic(at least that I've read myself). Follows an oblivious filly who survived what happened to Canterlot in the war and is trying to find her mom. Funny and sad at the same time. I was surprised how much I liked this one when I read it, don't recommend for a first FOE read.
https://www.fimfiction.net/story/662/fallout-equestria-heroes ← First Fic I read ever and what got me into pony. Follows Silver Storm, and the Equestrian wasteland around Dise, the FOE equivalent of New Vegas. Rough writing at start, but a great fic. Also thumbs up for Earth pony protagonists.
https://www.fimfiction.net/story/237525/fallout-equestria---infinite-potential ← Reading this one now and its also unfinished. It is also the shortest on this list. Follows the morally ambiguous Doctor Angel, an albino pony, after she is exiled from her stable. So far so good for me. Not sure what else to say about this one.
