Play this game on a rainy night with the lights out, it is all about atmosphere.
Most of what you do in the game is find audio logs left by your sister that tell the story of what happened in her life on the year you were gone. The story of your parents relationship is told through items from in the game, like letters and other objects. This is a game for people who really enjoy story in a game, so if you think "if I want a good story I will read a book!" then this game is not for you.
So if you like a good story out of a game and don't mind paying $20 for a 2-3 hour game then GET THIS GAME.
