I've never participated in this game, but I always really enjoy reading the updates. I don't think that anyone involved is really there for the prize; it's just a fun little bonus. These discussions just get creativity flowing and spark wonderful and diverse conversation about the industry and where it is going, can go, and so forth.
I could have tried to read up on old challenges to get an idea, admittedly :3
More than a fair amount. A lot of creativity.
I have a new understanding of what DC editorial must have done---and they couldn't just assign creators who are available and good for books. The real people would have to say "yes."
It was an interesting challenge. We butted heads a few times, but it's a good team, and I'm happy with what we did. Quite proud of my Midnight Suns pitch. :P
My first novel is up Amazon Kindle at http://www.amazon.com/In-My-Brothers...8184334&sr=1-1
And now in paperback, too!
