Impressive Madden fails to take the cake, with basic flaws leading the way.
Thankfully, the game isn't full of these frustrating details. The QB-cone of vision is a brillaint system that, while taking time to master, adds a necessary level of realism. Simple changes to blocking and tackling also lead to improvements in the run game. However, when compared to EA's College Football 06, Madden 2006 is simply not a clean game. There are too many simple problems to fault the makers and frustrate the players.
In all, it's a Madden game - new rosters, enjoyable gameplay. But I hope that 2007 brings a much improved game with fixes to the glitches.
