Easily the scariest game that I've ever played, and also the weirdest.
Aside from the scaryness, let's look at the other elements of the game. The graphics, are amazing, especially for its time (2003). The character design is outstanding and only a few recent games have achieved quality so great. And there is so much attention to detail, which is important in a game like this. The sound is similar with very creepy sound effects that won't let you down.
Next is the gameplay. It's from the third-person view, like the GTA games, and is actually really fun to play. There are various weapons to choose from and you can explore so much and you get a comment for almost every item you see, which is neat. I did find it hard to know where to go, since there was no waypoint marker like in Halo :(. I read on many forums that the combat system is flawed, and i respectfully disagree, i find it to be really fun to fight the monsters, and the way its set up seems great for me. Oh, and the game does not get repeatative, the environments get more and more wacked, and you also learn more about what's happening.
The story is the next part. It's simply the most **** up story i've ever heard. lol. But its still is a very good story, and sucks you in and creeps you out more and more. Heres a non-spoiler summary. A girl named Heather wakes up in an empty mall with monsters everywhere and sees this cultist who says gibberish and wants her 2 go to Silent Hill and then she does and then it gets weird lol. Good story though, very entertaining. This is also one of two games (the other is GTA 4) where the game is so realistic that you actually feel sympathetic towards the main character.
I sure had a lot to say about this game, thats cuz theres a lot about it lol. With all this said, its a great game and there is so much to unlock afterwards that will make the game even better (espiecially if you like Star Wars). And I dont think any other game will ever be as scary for me as this one was, enjoy!
