Much more than the sum if its parts.
The game play leaves you with a couple options. You can mash buttons until your heart is content and still likely make it through the game. But, the game rewards you for taking the time to learn the combos and special moves. After each session with this game I found myself looking to see what bit of concept art or game related video I managed to unlock. There were even times that I would replay a section because I just needed one more "token" to unlock something or another.
This game grabs hold of you from the beginning and does not let you go. The ride is short yet thrilling. The fact that the game is short does not diminish it's value. This games greatest value lies in its capacity to carry games at least one step closer to the kind of cinematic experience that can capture the pathos of characters situation
