Some 3-4 years ago, when I was browsing the web for FATE stuff, I found the Dresden Files site.
I was a bit excited by this, because I love FATE and urban fantasy.
When I read in January that the RPG would be published in June 2010, I started reading the novels. I finished all 11 of them in 6 weeks. At first, I was reading 3 a week, and slowed down later on to one novel a week. First this was intended to be a "research excercise" for playing the game, but the novels are page-turners.
Now, I finally have the PDF on my computer and my iPhone. I keep switching between the two devices to just keep on reading at every opportunity. I've read a lot of RPG rulebooks since 1987. I am deeply impressed by the quality of the writing. It is a joy to read and not a chore, like so many other rulebooks.
DFRPG did two things: finally get into the Dresdenverse, and introduce me to an elegantly written, well thought-out game system.
Great job!
