Hands down, one of the greatest pieces of story telling ever created on a video game. Now, with that being said. This is not an action game. Throughout the entire game, you probably only do about 100 button pushes total. This game is very similar in story telling as L.A. Noire, or Heavy Rain. You are not really playing, you are the author of the story, or the narrator.
Graphics are amazing. The way they made the characters look just like the actors was flawless, and I hope that other game studios in the future use this same tech on games, even if it is not for a main stream actor, just in general the facial capture and recognization is amazing.
So, if you are looking for full of action, take a pass on this one. If you are looking for a very thoughtful and thought-provoking game, then this is the story for you.
