So what is Frictional's opinion on Metro 2033?

[Your Computer]

Amnesia and Metro 2033 were the only games i remember to have ever make me literally fear-quit.

Concerning librarians, after building up the courage to walk through all of that, i stared at the librarian, but it attacked me. So i pulled out my shotgun and killed it (lawl). Half way into the area, i ran out of ammo by trying to take down just two or three of them. Thankfully by that time all i needed to do was ninja passed them.
