Silent hill 4 is an awesome game with some considerable flaws that prevent it from being truly great.
PROS: Creepy, disturbing environment just like the other silent hill games, great monster design, with a lot of variety, many different places to explore, highly engaging story, leaves you on the edge of your seat, plot twists leave you full of suspense and awe, Sidestep maneuver is a good substitute for the block from Silent Hill 3, and an overall fun experience.
CONS: Mediocre voice acting, characters aren't fully developed due to the voice acting, Combat system is kind of clunky, slightly unresponsive control, your room is the only save point in the entire game, boss fights are too few, and annoying NPC you have to bring around for the last half of the game.
The "obvious con" I didnt list was that it doesnt even take place in silent Hill. But who cares???!!! Silent hill was getting boring anyway. Its good that this game has some originality due to this fact. I mean seriously, people dont like this game just because it doesnt take place in silent hill. It really doesnt matter because this game keeps the disturbing and scary atmosphere that the other games had, but this is the scariest Silent hill yet. Silent hill fanboys may be dissapointed, but the average survival horror fan will like this game, if not love. Im not a silent hill fan but i played the others, and personally I think this is the most original and scariest one. The atmospheres are much more diverse, and there are unexpected plot twists along the way that make this Silent hill the most engaging and epic. If your just the average horror game fan, then give this game a try and im almost sure you will like it.
