This is one of the games you get and the more you play, the more you like.
Let me start by mentioning that I am not a big fan of the scary games. So people that enjoy these types of games, don't take my advice.
For those of my sort -- ones that don't like the feeling that you're going to die (i.e. rollercoasters, etc) skip this game.
This game does an excellent job with the gameplay, the story is great -- going back and forth into time (sure, a little ocarinaish) and playing the part of OTHER PEOPLE. (This is a lot different than anything I have ever seen.)
Anyways, It will scare you -- well, at least it did me, and If you like that, go pick it up.
