When I read that Mr. Fox had a dream world, and Fishlicka made sure to explain that you want to avoid spoiling it, I had an idea of what I thought it would be.
Remembering seeing it said that Fishlicka had a mind to try more "classic" shooter weapons like shotguns, SMG's, and other realistic firearms, I had thought that Mr. Fox's dream was going to be a relatively photorealistic world with blood, crime, delapidated neighborhoods, and realistic weapons. It would have been a major twist, in my opinion.
