That maybe so but that just goes to show that when people say Kojima's style wouldn't fit Silent Hill due to his lack of subtlety, they mainly mean Silent Hill 2.Silent Hill 4 is a bad game too. It was the beginning of the decay.
Silent Hill 1, 3, and 4, are way less "subtle" than most remember I reckon, and yet they were mostly all made by members of the same development team, showing that there isn't just 1 style that SH games need to adhere to.
