My name is Joshua Yearsley.
My passion is turning complex ideas into easy reads. Whether you’ve got a game, book, or technical document—I’ve got you covered.
Through editing more than two million words, I’ve developed a process that works, using the principles of curiosity and play to make your writing more precise and enjoyable.
The Three Pillars
Substantive editing considers it all: structure, style, consistency.
I’ll not only make your work concise, clear, and organized, but also highlight your writerly voice.
Then, by personalizing a style guide, I’ll polish your work to make it professional and persuasive.
Rulebooks & Manuals
This step is especially important for technical manuals and tabletop games—the rulebook is the heart of the play experience.
I collaborate with expert developers to collect and analyze feedback from their networks of playtesters experienced in your game’s genre.
Two Heads > One
Substantive editing prompts major changes and improvements. And in these cases, nothing helps more than a second set of skilled eyes.
To make sure your work comes out beautiful, I team up with professional editor Kate Unrau as my dedicated proofreader.

I’ve run Editor Extraordinaire! full-time for four years now. Before that, I was a scientist. I have a master’s degree in materials science and engineering, and I’m published in both science journals and technical magazines.
Bringing together my scientific background and love for games, I’m equally at home working on articles about modulating Fermi level pinning at metal–oxide interfaces and on games about noir investigations and druidic magick.
