"But recently a writer/illustrator broke $1-million in pledges on Kickstarter – probably more than a publisher would have given him as an advance."
I guess the use of the word "probably" means they think there was some small possibility that, 6 weeks ago, some publisher could have been offering Rich a million-dollar advance, if he'd only thought to check in with them? Now that's optimism, right there.
Wizard's might be happy to do so. However, Rich would lucky to have his soul after that.
Yes I know TheGiant has worked on some official D&D books and has had OOTS in Dragon Magazine, but the point is i am sure publishers would give Rich a lot of money, but he would probably lose most of his rights, including the right to sneeze.
