The last Guardian video game

I don't know what to say.. just wow will do.  Ok that won't do.  I think this is actual game play and not a filmed segment and the almost instant personality of the Guardian is remarkable.  It is a bit unsure of itself and hesitant.  It shows some concern when he stumbles a bit on that narrow walk at the start.. it is just very aware of him.  I wish I had a playstation.. sigh.
