There's something that has been bothering me about Resident Evil 5

Many things, actually, but this is the main one, and no one I've discussed it with seems to want to acknowledge that this interview exists:

So it's a year old and whatnot, but the whole thing about your eyes needing to adjust to the light/dark depending on the environment...That's not in the game at all. And as I understand it, that was supposed to be a pretty huge element of the game. I'm just wondering why they decided to take it out.
