@I Moon Girl I agree about alien isolation---just never got scary for me, and was way too tedious. You want scary? Try Outlast (or outlast 2, it's fairly new and I haven't tried that one yet, but its gotten decent reviews and seems to carry on the "scariness").
I have almost pulled the trigger on the Last of Us, but just haven't yet, so I'll have to give that one a try, as I know it is supposed to be supremely scary as well, and apparently you feel it is too!
BUT, try Outlast, if you haven't yet! Turn the lights off and put on headphones...but don't say you weren't warned, lol!
