I know people like to blame Smith, but he did leave and, if you listen to Spector's interviews, Spector honestly believes that these are all great, wonderful things.
We have a winner!
Spector was constantly promoting IW throughout its pre-release marketing. Regardless of who fucked the game up, he put his reputation behind it in the interviews he gave and the messages he posted. He even continued to defend it after it came out.
He didn't
have to do any of this. He could have just kept his mouth shut and directed all inquiries to the PR dept. or Smith himself. Instead he fully endorsed the game.
Good riddance.
