I won’t be starting my choose-a-path story yet, as we’re still in construction and don’t have enough members for the voting. In the meantime, I’ll suggest a fanfiction for you to read.
I tread carefully when it comes to fanfic, because it drives me insane when characters aren’t portrayed geniune to their original selves, or when fans create really bad romantic entanglements. But I did manage to find one fanfic that I’ve rather enjoyed so far. It’s a fanfic of the “Big Bang Theory” TV show, written in script form, and it stays true to the characters and the geeky humor of the show well. A new episode was just posted today, and you can read it all here: http://www.fanfiction.net/u/2794367/
All in all, this writer has five episodes up. There is a fan-created character involved, but one that so far integrates well with the original cast of characters. So if you like the “Big Bang Theory” TV show, check it out!
