Conclusion: While initially not my first choice, I was won over by the online gameplay and the price tag of $20 less than either madden or espn's current offerings and have not been dissapointed. While there are a few drawbacks, mainly in the audio and some repetitive screen shots, the look feel and features are very enjoyable and will appeal to both the casual football game player and the more serious as its easy to tailor the game to suit your style of play.
Summary: this game is easily way better then madden nfl 2004. i've been playing madden for years and this years version of madden is like playing in fastforward. nfl fever 2004 is graphically superb the gameplay is excellent the coach's advice from the sidelines is a nice touch. the camera system is perfect. i cant find any fault with nfl fever 2004, it's damn close to perfect, a must have for all sports game fans.
Summary: NFL Fever 2004 is really a great game, especially if you aren't a harcore player and it's the first time you play a NFL game. Madden is much better, as you can see in GameSpot's and IGN's reviews, but it doesn't support XBOX Live gameplay. Fever has the XSN mode that allows you to join tournaments and see you standings on xbox.com web, but if you are not using Live, the decision is clear: Madden 2004 is better game.
