Great game, improvement from last year...
Graphics weren't much different, but I didn't mind that - I was happy with the graphics last year anyway. I really like the new Superstar: Hall of Fame mode, what with all the new features in that such as specific camera angles and hands-on playing with your player. I'm also impressed with the new running features. I often take control of my fullback or tackle to blow defenders away from the back, and I frequently use the new Highlight Stick.
All in all, the upgrades to this years Madden make it a truly great game. I can't wait for future, complete versions on the new generation of consoles.
