PIAC, Silent Hill is a PSX/PS2 franchise that I am actually quite fond of.
The first game started out with you in the car with your daughter. You see a girl standing in the road, and you swerve to avoid her, and your car crashes. When you wake up, your daughter is gone, and you are in a tourist resort known as Silent Hill. The town is strange. It's snowing and foggy in the middle of the summer, and things just aren't as they should be. If you play the game, it really starts to get weirder yet.
The second game starts out with a man who has recieved a letter from his wife who was dead for 3 years. It was postmarked from the last week, and it said that she was "waiting for him" in Silent Hill, where they had some good times together years before when she was still well. James drives into town seeking his dead wife when the game begins.
The gameplay is fairly standard fare, much like Resident Evil, but a million times easier. But you have a radio that really creeps you out by emmitting static whenever a monster is nearby. The music is largely industrial flavored, but really serves its job well by providing a great amount of atmosphere to the game. Couple this with an insanely low draw distance that's hidden by a LOT of fog, or by pitch black darkness, and you have a claustrophobic game that will scare the pants off of you.
What REALLY gets a person about these games though, is the story. The story is too high level for a lot of gamers, and many people just don't get the true genius of it... I know I sound like a crackhead right now, but it's true. Resident Evil features a very linear storyline. The games may not tell you all the details, but at the end of the game, you feel like you have a good idea of what went on in the game. Silent Hill doesn't leave you like that. People can discuss the plot, and write their guides all they want, but I feel that the story isn't truly SUPPOSED to be known to the player. It's more of a case of where you can make up your own mind what the whole thing meant at the end of the game.
Suffice to say, the endings of both games will haunt you forever.
