The models in GT4 are fantastic – photorealistic models that can get dirty with use (of course, there’s still no visible damage – license issues, you see). The photorealism is not restricted to the vehicles, however, but include the tracks and environments as well. Crowds that would be simple paintings in other games take the form of simple models that watch and cheer as racers go by – even standing in the middle of the track to take photos, then rushing out of the way in the Rally races. J.R. Nip did manage to illustrate that the crowd goers were not very highly detailed, but they weren’t intended to be driven up to (and into) and scrutinized to such a degree. For the speeds you’re intended to pass them at, they look more than believable.
The music available in GT4 is as varied as it is plentiful. You have the ability to go into a menu and select which songs you want to have in the playlist and whether you want the song to be in the gameplay or the replay. I tried deselecting all of the songs except for the classical songs and raced around to classical music. That is an interesting experience in contradiction; the sound effects and visuals are fast-paced and intense, but the music is calming and relaxing. This contributes to a very surreal racing experience.
