I personally find SH4 as the best and most creative in the series since SH1.
Its true that it gest a bit boring at some parts but after you reach a point it gets very interesting and very very challenging compared to SH2 and SH3 which were easy to beat.
I stopped halfway as well because it gets annoying.And I mean the good silent hill way.
My appartment is transforming into hell and its dangerous just by being there.
Oh and just love the small touches here and there
A tip for those who are still at the beginning:Save as much health drinks as you can.Try not to use them at all.Try to heal in the room because later not only you wouldnt be able to heal there BUT.......oh well dont want to spoil it for you
