Have you ever noticed how in most movies and games about zombies, they never tackle the psychological damage that happens to the remaining survivors. It's always about the superhero that swoops in, kicks major zombie ass, and escapes to safety. But in a real apocalypse, It would be a lot more traumatic. There is one game I picked up that tries to show that side of it. If you follow the story, it does it very well for a game. I think that more movies and games should try to catch the uglier side of the zombie apocalypse.
