For years and years the Gran Turismo series has been considered the benchmark by which all other realistic console racing games are judged, and for good reason. Few games play as well, are as challenging, or look as good as this hardcore racer. However, the game has started to age over the years, and like many of the cars it features, the series is due for an overhaul. Luckily for Polyphony, it's got all the power of the PlayStation 3 at its disposal to bring the series into the HD era. Gran Turismo 5 isn't scheduled to come out for some time, but we'll get a taste of what's coming a bit sooner thanks to Gran Turismo 5: Prologue.
