Fantastic, but has some minor problems. Buy it anyway, especially Resident Evil fans.
The review (out of 10):
Story: 10
The story is amazing. You play as James Suderland, a clerk who's wife mysteriously died three years previously of a terminal illness. You receive a letter from her (presumably) and set off for Silent Hill to find her. There are other characters who's stories are mostly explained throughout. Also, there is a sub-story where you play as the character Maria and learn of what led her to be at the docks when James met her there.
Graphics: 9.5
What the graphics are missing are things that probably could not have been fixed at the time, as the PC version is essentially a port of the PS2 version. The problem occurs mostly in the cut scenes: the voices don't match up with the mouths--BUT! the mouths are clearly saying the dialogue.
Sound: 10
Absolutely perfect. This is where the game wins against Resident Evil. The game supports Dolby Digital 5.1 Surround (on my laptop it says that it also supports 7.1). The voice casting is perfect, adding to the story. Also, it should be noted that the character-to-character dialogue is far, far superior to Resident Evil's.
Control: 9
A PS2 game on PC is somewhat more difficult without a game pad.
Replayablilty: 9
What the game is missing is more "stuff" to do in it. The sub-chapter I finished in under an hour and the game itself was about 7.5 hours for me, a newcomer to the series. The game does sport 4 unique endings that supposedly give more insight into the story. I'd play it again just to see Pyramid Head.
Other:
What the game suffers from is some unnecessary flaws in its essential play. Every time you solve a puzzle--which involves collecting items, opening up the inventory screen, and figuring out what to do. The problem is that for every piece you insert into the puzzle, you have to look at the puzzle, open up your inventory, place only one piece--but you have to remember what you are going to do, otherwise you have to re-do the entire thing. You cannot check what you're doing while doing it and you must open up your inventory every time you need to put something in. This is a minor flaw that is easily overlooked with the brilliant game.
Overall: 9.2/10--I'll round up to a 9.5/10 because it's so much fun to play.
The game is HIGHLY ADDICTIVE. On the cover of the box, there is a quote from Playstation Magazine: "So engrossing that you simply can not put it down". That pretty much describes the game. It is well worth it. Go get it.
