Car Customization

As in the preceding Underground installments, the performance and physical appearance of the player's car could be extensively modified, but options for exterior modifications have been simplified to only the essentials, with specific parts (i.e. individual bumpers, side skirts, lights and exhaust pipes) foregone, and are primarily used as methods of decreasing the car's wanted level, compared to increasing a car's "reputation rating" in the Underground games. Additionally, players are allowed to assume a sleeper appearance for cars without penalty in Most Wanted.

A decision was made not to include online play for the PlayStation 2 version (including the Black Edition, despite fan requests). It is speculated that EA Games had dropped the PlayStation 2's online services in favor of Xbox Live for the Xbox and Xbox 360.[citation needed] However, the PlayStation Portable version of the game would support this feature. Both the PlayStation 2 versions of Underground and Underground 2 had previously included online play.

EA has quit support to the PC version of the game very early from its release, even with the community asking for another patch to fix lasting bugs, the latest patch for the PC version (1.3) was released on December 6, 2005.
