Sometimes, you just have to look at the bright side. Maybe Polyphony need the extra time to include new gameplay features, tracks and cars.
Gran Turismo redefined the driving game genre by offering a simulation approach in an arcade-style game; it was beautifully addictive and playable. Gran Turismo 3 was scheduled for release in Japan on the 15th of February. That date has now been put back till April. The American version will come out a couple of months after Japanese launch. Europe on the other hand, can expect GT3 a few months after the American version. Try not to count the days until launch… when it comes it will be worth it.
