Witcher's author sued CD Projekt RED

That aint how ip rights work

He's also been a total ass about the games, as well. He's just pissed that the games have become more popular than his books. He's bitched that the books use art from the games for their covers in other countries, and has said that the games aren't the "true" story, because only he can tell that. He's come off as an old, bitter, entitled jerkass the entire time, this is just the clincher.
