I slept of the first game, and I regret doing so, I'm definitely going to have to track down an original copy. This game is truly disturbed at times it makes you not want to look at it, yet addictive enough to where you can't turn your head way, even when it's making you sick (and it just might, I got headaches at first when I played it for more than half an hour). That makes for the perfect formula for a horror game, and I personally can't think of any other that have got it this right since the old Resident Evils.
I suppose it's like the bastard love child between Fight Night, Resident Evil, and Fear. It definitely takes some getting used to, and isn't for everyone, but if you give it a chance it just might suck you into its twisted world. If that sounds like its up your alley I would suggest picking it up, you might even be able to find it for a couple dub cheaper than most new games if you shop around.
