Credit where credit is due, this game is absolutely outstanding. I've only played a few of matches on XBL so far but I can already see what a monumental leap this is for football games. Thank the lord that someone high up at EA decided to change paths from the twitchy/arcade Fifa's of this gen (though I did enjoy them) and opt for a more simulator approach to football. I won't go into too much detail because i'm itching for more play -but everything from the animations, graphics, pacing, and the new impact engine are just perfect. Precision dribbling is finally becoming apparent and the new defense system is a game changer. Stadiums look incredible, some of the player likeness is uncanny. It actually FEELS like a football match, from the build ups to the frustrations of when your shot hits the post and your player falls to his knees and punches the grass. It puts you right in the match and you actually feel like what you are doing is having an effect on the way the game unfolds rather than just watching a bunch of animations and playing pinball. Most importantly of all tactical defending is mandatory on XBL and so you no longer have to sit there and watch yourself being completely owned by someone holding the A button!
I won't babble on anymore - but just say that the demo did NOT do this game justice. If you're looking at your gaming shelf and FIfa 12 isn't there, it damn well should be.
