Gameplay

This game introduced the ability to race with up to 16 cars at once to the Gran Turismo series. According to game developer Polyphony Digital, the NPC's AI has also improved from previous Gran Turismo games.Gran Turismo 5 Prologue official website - Introduction

New to the series is the realistic in-car view feature. It includes functioning speedometers, odometers, reflecting rear-view mirrors, wing mirrors and real-time in-car lighting effects, such as shadows. Players driving with either the control pad or the steering wheel can look left and right in the cockpit of the car by using the D-pad. This function can be mapped to other buttons on the controller if preferred. Any PlayStation 3 - compatible steering wheel works with Gran Turismo 5 Prologue. Three viewing modes show the car from exterior angles. The fourth, called "cockpit mode", includes the driver's perspective from the interior of the car looking past the steering wheel to the track and is available only for "premium" cars.

The Spec II update brings Drift Mode (similar to that of Gran Turismo HD Concept), car tuning adjustments, and head to head two-player racing offline.

Online Gran Turismo 5 Prologue is the first mass-produced Gran Turismo game to feature online multiplayer. Up to 16 players can play online at once in GT5 Prologue. Since Gran Turismo 5's development cycle was so long, GT5 Prologue's servers were online for two years even though the game only served as a prologue. Gran Turismo 4 for the PlayStation 2 was intended to contain an online component, but this feature was pulled before the game's release to avoid further delays; a beta of GT4 online was even released.Gran Turismo 4#Online test version Gran Turismo HD Concept also contained an online Time Trial feature.Gran Turismo HD Concept#Game modes

The latest update, entitled Spec III, added new cars and further improvements to the game and was released in October 2008. A separate disc was also released in Japan that included all updates, including Spec III. The Platinum release of the game, originally unveiled in Europe, also comes with the Spec III update.

Interface

The game has a brand new interface called 'My Page' that acts as the player's personalized menu for the game. When the game starts up, the player is taken straight to this interface, and the currently selected car is displayed on the screen in a picturesque real-life location. The vehicle is set in a Full HD advanced 3D environment with a 360° camera and the GUI's real-time zoom-in function is enabled.

In the Japanese version, the 'My Page' interface includes: News: a regularly updated online log archiving game news such as newly added Online Event Races, VOD programs or technical information such as server maintenance schedule. GT-TV: a Video-on-demand service was offering free of charge and playable HD content. Available videos are real-life car-related videos such as new model tests, Auto show reports, car documentaries, or special event videos. Game videos such as opening and ending movies are also available for download from the Blu-ray Disc to the console's HDD once unlocked. However, premium content was discontinued on December 29, 2009, to move focus to the release of the full game. Online: Online Events consist of either multiplayer races from 2 up to 16 players (some of which are world scale), or online Time Trial events. Each event is limited in time, once finished, a ranking board shows the most successful players' scores. Top players' replay files are made available for download as ghost replays. Each week new events with their specific parameters (car class, tire types, assistance level, etc.) are added to the list while older are closed. Ranking: an online ranking board for each course archiving the best record per track and car. Arcade: a single race mode is allowing the player to choose a track to race on board the currently selected car and to compete against 15 AI-controlled cars. Credits are not earned in this mode. 2P Battle: an offline two-player split-screen mode. Event: Event Races are championships, time trials and mission races against the AI in various classes. Once completed in Gold, Silver, or Bronze level, new, harder classes are made available. Credits are earned by the player as he wins the races in top positions. Three basic classes are available Class C, B, and A. Once Class A is completed, the game's ending movie is available for download in GT-TV, and a bonus class called Class S is added. Garage: where the players' cars can be viewed, raced and also sold to earn credits. Dealerships: where the player can buy a new car using credits earned from Event races. Various models from world-famous automakers are available for purchase in the showroom. Some automakers have their Event race consisting of a one-make race for a specific model. Brand related News is regularly provided through online updates. Replay: saved or downloaded replays are available for watching. Option: various options settings for the game. Manual: the game's Playing Manual is displayed on-screen. The Manual is almost always updated with a software update. Save: allows to record the game when the auto-save feature is disabled.

When the user's PlayStation Network account is signed off, online content related icons are disabled (1, 2, 3 and 4). The Museum is activated from the 'My Page' interface once the game is in rolling demo mode. This feature provides the players with automakers' background and history.

Updates Updates were available on game boot through online download, all free. Game content such as new cars, game modes or GT-TV videos were added with each update. Some elements such as BGMs are regionally exclusive due to licensing issues. Once Polyphony Digital begun to focus on Gran Turismo 5, it stopped applying updates to GT5 Prologue.

GT-TV The Gran Turismo TV feature was introduced in the free demo version. The VOD service was activated on October 22, 2007, providing free SD trailers for three upcoming GT-TV programs, Super GT ("Climax Digest"), D1 Grand Prix ("Top of the Drifting World") and Best Motoring ("Best Motoring Trailer"). From October 22 to November 30 three GT-TV exclusive HD videos featuring game producer Kazunori Yamauchi premiered in the demo: "First Impression: Lancer Evolution X", "Tokyo Motor Show 2007" and "GT-R Legend Inside Story part I".

The demo was removed from the Japanese PlayStation Store on November 30 and its online functions ended on December 6, however all issued VOD videos were later re-released in the game's retail version through updates, except the SD trailers. "The GT-R Legend Inside Story" part 1 documentary was included in the Blu-ray Disc though. It was later completed by parts II & III, both released through GT-TV updates.

The first episode of the BBC's Top Gear series 6 was available for free since March 31. In the meantime, five videos released in December 2007 have been removed. On April 1, two promotion videos for Super GT ("Fascination for the Super GT") and D1 Grand Prix ("The Drifting World") were added. The first trailer for Video Option ("What is the Video Option?") was also included announcing upcoming releases for this magazine.

On August 1, 2008, GT-TV was completely overhauled with a new interface, layout, and the launch of the PPV (pay-per-view) service. The "GT-R Legend Inside Story (all parts)", "'08 Nurburgring 24h Introduction" and "First Impression Lancer Evolution X" videos stayed free-of-charge. "Fascination for the Super GT", "The Drifting World", and "What is The Video Option?" videos were taken off of GT-TV."Viewing of Programs Distributed Before The Update". The new update added new PPV videos; 8 Top Gear videos, 1 Option video, 1 Super GT video, D1 Grand Prix video, 1 Gran Turismo video and 1 Best Motoring video. Also kept were the opening and ending movies, also staying free-of-charge. All PPV videos were released at a reduced price at the launch of the service."A Grand Update for Gran Turismo 5 Prologue". When asked whether the GT-TV service could come to the PSP, Yamauchi answered, "We definitely want to do that in the future", suggesting that watching GT-TV on the move could become a reality in the future, but this never happened ultimately.

Cars The Japanese release in December 2007 featured 37 stock cars (plus the uncredited GT-R "Black Mask" returning from the free playable demo) from various Japanese, European and American manufacturers including Nissan, Ferrari, and Ford. While GT3 and GT4 did have Formula One cars, GT5 Prologue was the first of the series to feature a fully licensed F1 car, the F2007.

The Spec II update added new manufacturers, more stock cars and introduced racing cars and tuned cars. The update brought the total number of playable cars to 71. The North American version of Gran Turismo 5 Prologue brought additional stock and tuned cars, increasing the game's car list to 76 credited cars.

Tracks Four circuits located in Japan, Europe, and North America are included in the original game, plus two fictitious tracks: The High-Speed Ring and Eiger/Eiger Nordwand. In the absence of suitable roads in the real-life location around Kleine Scheidegg and the Eiger, the game developers created the track based on an actual hiking trail.

Each track is available in two different layouts. London, High-Speed Ring, and Eiger Nordwand are available in the forward and reverse directions. The Fuji International Speedway is available in both "F1" and "GT" variation; the Daytona International Speedway has both the Oval and Road Course layouts; the Suzuka Circuit has a shorter layout known as the East Course. Each real-life circuit has an HD video "Course Guide" that documents the location with actual footage and commentary text.

Spec II update adds the Gran Turismo franchise's classic High-Speed Ring fictitious circuit (available in both forward and reverse version) which brings the total number of tracks to six (twelve different layouts).

Input device support The Gran Turismo 5 Prologue free playable demo was the first PlayStation 3 release supporting both Dual Shock 3 controller vibration and racing wheels force feedback feature. On February 20, 2008, Logitech announced a new Gran Turismo official wheel, the Driving Force GT to be launched in May to coincide with the game's western release. Previous official Gran Turismo wheels are supported, which include the Driving Force Pro, GT Force, Driving Force and Driving Force EX. Limited support for the Logitech G25 Racing Wheel is available; the wheel is not officially supported, but it is possible to re-map the button layout via the Driving Force Pro setup screen and the clutch can be enabled by pressing the triangle button at the start of each race, as soon as the player has control of the car. Support for the Logitech G27 is also limited, for example, the paddle shifts do not work in-game, although the paddle shifts signals are detected (up and down) in the controller configuration screen.

Release Japanese PSN demo A free demo (グランツーリスモ5 プロローグ 無料体験版) was made available for download between October 20 and November 30, 2007 in the Japanese PlayStation store with the Suzuka Circuit and seven playable cars. The demo unlocked cars as they were unveiled at the 40th Tokyo Motor Show. This demo replaced Gran Turismo HD Concept that was removed from the Japanese PlayStation Store on September 30.
