Please pm me if you'd like to help create an Fallout 4 fan fiction story
I'm five chapters (about 33,000 words) into writing one of those. Real life has me seriously slowed down at the moment.
I've done that as well (reviewed and edited). Your initial post wasn't exactly clear on that.
I'm quite serious in wishing you good luck with it, simply due to the genre. I ended up using someone local as my first reader for my Skyrim novel simply because you don't just need an editor, I thin you need someone who is familiar with the background of the actual game and alternate Fallout universe.
