There is a lack of good EGS fanfic out there, which is a bleeding shame because the world Dan's given us is WAY too fun to not be explored in writing. This topic, then, is both to catalogue the joy that is Shivefics, and to encourage forumgoers to write their own!
Just one caveat - please LINK to fanfics, rather than posting them here. Discussion of said fics is still cool. An Archive Of Our Own is a good place for completed works (as well as the venerable Fanfiction.net); for WIPs, may I suggest Pastebin?
FICS:
-Raven's Thoughts, by LoreWren. http://archiveofourown.org/works/311446 - A prose version of one of the 4th wall mail slot comics. If you like Mr. Raven, you'll like this. G-rated.
-Silly EGS One-Shots, by yours truly. http://archiveofourown.org/works/5312912/chapters/12266816 - This one's a what-you-see-is-what-you-get. Presently sitting at five one shots, PG-13 at the worst.
-First Contact, by scriptdragonslayer. http://archiveofourown.org/works/5070703 - About Susan's OCD and overcoming it. Susan/Elliot, light shippiness. G-rated.
And now, for those that have not yet seen it (and hopefully to spur discussion and writeyness): 50 EGS FANFIC PROMPTS.
