Having played NFL games since Joe Montana on my MegaDrive. I can honestly say that the 2 bad reviews above, are from people playing the demo.
This game is a move forward from last years. The player animation is much improved, with players pulling and tugginf at shirts. With pretty much every attribute customisable you can really tailor the game to your needs and skill level.
The introduction of GameFlow helps speed the games up and takes the stress off picking the right plays for the novice gamer. Its not fool proof it can pick plays that are wrong for the situation, but with in game calls to adjust formations its easily rectified.
Whilst its a little way behind the polished look and feel of FIFA 10/11. Its a great game and a must buy for any NFL fan.
