New features in Madden 2004 include a new owner mode option that allows the player to control a franchise. In this mode, the player takes on all the responsibilities related to owning a professional football team, from regulating hot dog prices, to team relocation, to hiring and firing coaching staff. Another new feature is the ability to edit a historic team. Also, a new training camp mode, occurring before the preseason, that can help player progress faster by putting him through mini-camp drills.
This Madden game is best known for its version of then-Falcons quarterback Michael Vick, an arguably overpowered character and by acclaim the greatest Madden player of all-time due to his 95 speed rating. In 2016, developer Clint Oldenburg told Gameradar that over the next several years "features were added to the game specifically to stop Vick." The 04 version of Vick has been used in Madden NFL 25 and 15 in Ultimate Team mode as a 99 overall with either 99 or 100 speed.
The soundtrack of the game features various hip hop and rock songs.
