19€ for 2-hours in an empty house... (If you pay 60€ to play CoD singleplayer, simply ignore this critic)
The story is just for company, the game is basically just exploring and the only puzzle you'll find is searching for keys, codes and maps to certain doors, and i'm sorry to disagree, but it isn't a "great story", *SPOILER [it's a romance between "your" sister and another girl, and that's about it, nothing new really, just the expected: "Mom and dad don't understand, i'm such a tough teenager i'm going to run away" kind of things. I'm being a bit unfair, the story is way better told than those Disney Channel series, but...it really sums down to that, guys...] :/
The strongest point here is the house, and it is amazing. The many details, you can touch everything, and when you *SPOILER [find the tunnels you just feel like a child and you REALLY want those in your house] and last, the music, really good choice, I liked all the songs.
Good
-scenery and environment
-music
-interactivity
Bad
-story (but apart from being predictable...very predictable, it is well told)
-longevity
-not much of a challenge (but it isn't supposed to be, anyway)
