Wait a second. Final Fantasy XIII isn't the most panned title, and Nomura wasn't directing that game at any point. Heck, not only it is a Toriyama-directed game, but Nomura only designed the main characters; there was a different art director altogether for everything else.
EDIT: Nomura got also kicked out of FFXV (or Versus), and SE continues to overcharge him with work to do on other games. How is the dude to blame?
