Man fuck that author completely. I don't like the idea of people being taken advantage of or not being paid for their work but they offered dude a deal and he balked and demanded cash and they fucking agreed on it. He signed his godamn name and proceeded to trash said company and games in general until he realized that their creative endeavor was - and will forever be - wildly more sucessfull than his stupid books.
I know the country he's based in has some insanely leniant laws favoring his argument but i hope something turns the screw on this dudes life at some point in the near future for being such a douchebag.
The funny thing is that without those stupid books, the franchise you love wouldn't exist at all in the games. And before you come with the argument of the games making it popular, even if we take it into account (which wouldn't be true in poland and eastern europe at least), the creation of the series came from him much like the same is true for Tolkien, JK Rolling and many authors in the world.
