ExtrasThe initial US PS2 and Xbox releases include an AND 1 mixtape DVD and the soundtrack by DJ Green Lantern.
DJ Green LanternIf you play as the character DJ Green Lantern and keep pressing the Taunt button, the DJ will do random shout outs to the development team members, along with other amusing quotes.
Motion CaptureAll the moves and dunks in AND 1 Streetball were motion-captured by the actual players who perform them in real life. The process took over a week and involved many hours of footage.
Voice RecordingThe voices heard in the game are the actual AND 1 players, Duke Tango, and DJ Green Lantern. Everyone did audio recording sessions following their time in Motion Capture. Often, the players were encouraged to come up with their own "Trash Talk" for a more real streetball experience.
