They are so big, it's the exact same thing that happened with mainstream 'Hollywood' movies.
People don't expected 'San Andreas' to be a great creative film. They expect explosions, great special effects and a scene where The Rock gets to act tough - bonus if we get a tender scene.
Many 'big games' are suffering the same 'too big to take much of a risk' issues. Look at how Mass Effect 3 was clobbered? They took a risk - customers - at least the loudest ones - hated it. It hurt the game, and games that follow.
Fans are part of the problem with this happening.
