This is an AWESOME game!!!!  I have played the other two and they were kick ass as well, but this one is fantastic.  I just started it, and don't have as much time to play as others might have, but I recommend it, especially if you played the last two in the series.  The graphics and movement are smooth and crisp.  The controllers take some getting use to since the you are upside down on some stuff.  I am looking forward to getting deeper into the game, might cut into my Socom time. lol
