In Europe, the game was bundled with a promotional "Making of DVD Video". While intended to be a limited content, the DVD-Video was also included in the Platinum re-release. The DVD was later included in the limited "Gran Turismo 4" "Special DVD Set" released in Japan on June 28, 2004. The regular edition was discontinued and the game was re-issued under Sony's 'Greatest Hits' line in Japan ("PlayStation 2 the Best") on August 5, 2004 and Europe ("Platinum"). As "Gran Turismo 4" was intended to be released in time for the worldwide 2002/2003 Christmas release but was delayed, in consolation, Polyphony brought out "Gran Turismo 4: Prologue" as a sneak preview (including a documentary bonus disc in Europe) to the full experience of "Gran Turismo 4".
