One thing that surprised me...

[superluser]

There's full frontal nudity for men in this game.

Obviously it's far from titillating, being dead and all; and 95% of players will be straight men or gay women (maybe), on top of the fact that it's not meant to be seen in that light.

One question is why not women? Or did I just not notice?

From a realism standpoint you're right, of course. From the perspective of horror, it drives home the fear that the (predominantly male) players have of their frailty and for some, their feelings of inadequacy.
