I only played the demo for 4, but it seemed there was a lot of 'pixel hunting' and use of silly triggers going on? Like "examine this bit of wall, then use the phone twice to trigger a cut scene, then you can check the wardrobe where something has randomly appeared". The random stuff wasnt scary, just annoying. I liked the idea of SH4, it was just poorly executed imho.
SH1 and 2 were my favourite for different reasons, but 3 was a little mundane..I never finished that one!
