Gran Turismo 5: Prologue contains a small sample of Gran Turismo 5 but was released as a stand-alone game, a tradition started with Gran Turismo 4: Prologue and is made available at a lower price than regular PS3 games.
Widely based on the Gran Turismo 4 engine but with many minor tweaks and changes, it contains more than 60 representations of real cars, five tracks and three series of events. It also contains improved support for Logitech Driving Force steering controllers and a wider variety of options. Ferraris will be included for the first time in the series and it includes visible car damage.
The driving physics have been improved on and cars handle more realistically than in GT4. The game contains more music, ranging from lounge and jazz-funk to indie and electronica.
The base version is upgraded through different digital downloads, adding new modes and videos (1.11 – December 2007) and a much larger update (2.0 – March 2008) with new cars, circuits, modes, events and different features. Since 2.0, the game is referred to as Gran Turismo 5: Prologue – Spec II. That version was updated once more in April 2008 as 2.10 with more features. These updates are free to download, but in some countries the updated version is actually the retail one. PAL regions received the 2.0 version while North American received 2.10 by default.
