The main thing about it is it's scenery and story telling and the whole game is beautiful and all, but for you who are not really craving to get it, I suggest looking at videos instead, it's basically the same thing, it has really cool places that you are in though.
It's not really a game as people refer to it, it's a story in a 3D format kind of, if you're interested but don't want to pay for the game my friend Frost did an entire playthrough of it. Click here.
