"FIFA Football 2004 is the eleventh game in the FIFA series and the eighth to be in 3D. While not adding much to the engine used in FIFA Football 2003, the biggest inclusion were secondary divisions, which allowed the player to take lower ranked teams into the top leagues and European matches. Gameplay had a new feature dubbed Off the ball, which required the player to control two players at the same time to execute some plays. The online mode was boasted as the main feature. Another key feature was the Football Fusion, which allowed owners of both FIFA 2004 and TCM 2004 to actually play games from the management sim."
