Herd nerfer does make a good point. If anyone, such as myself, has a reaction to a certain element of a game we have a personal responsibility to choose how we interact with the game. The number of people mentioning effects of headaches and dizziness seems to be high so CG could try and implement good ideas suggested by others such as a static background.
I think CG trying new content is always welcomed and if they react to feedback, great, if not people will just auto and not really get involved. I dont think there will ever be a perfect fit for all and whether its motion sickness, dyslexia or even common colour blindness there will always be something that CG hasnt thought of.
