Recently played it for the first time ... My score would be 8.5/10 (my silent hill experience being limited to SH 1, 2 on PS 1-2), it really plays own the gamer's psyche and develops a really nice gaming atmosphere!
Addendum------ It has a kickin' soundtrack, if not the best OST I've heard in a game this year.
