I'm playing through at the moment, and it's great fun. I have noticed a couple of graphical glitches, but nothing game breaking. I tend to dislike tight FOV as it makes me uneasy, but the use in this case aids the development of a very immersive atmosphere. The development team have done an amazing job, on my 7 year old computer, it runs on near optimal settings flawlessly. I get the impression that some people feel they were entitled to adjustable FOV? A shame that something so trivial has so much sway.
