Every time i enter a fog gate to fight a boss battle in Demon's Souls it makes me more scared than any of the Silent Hill/Resident Evil games ever did.Especially worlds 3.1,3.2,5.1 and 5.2 are seriously smurfed up.Of course the fear of loosing all the souls you carry plays a role too.

I have the first Project Zero game and all three Siren games but unfortunately i haven't really played them yet.
