Part 'teaser' for GT4 and part training product, Gran Turismo 4: Prologue has already enjoyed huge success in its native Japan. The European 'Signature Edition' will include 46 tests designed to hone every aspect of players' driving skills and feature 64 different cars - well short of GT4's 500+ vehicles but a pretty healthy number all the same. Players who complete all of the tests featured in Prologue Signature Edition will be rewarded for their efforts by getting a headstart for GT4 saved on their Memory Card.
As an added bonus, GT4: Prologue Signature Edition will feature an exclusive 'Making of' movie, which gives you a behind-the-scenes glimpse of the hugely anticipated GT4, as well as a few pointers on what makes a truly great driver.
