Gran Turismo 4 is a 2004 racing video game for the PlayStation 2, the fourth installment in the main Gran Turismo series and the sixth for the overall series. Players accumulate points by winning races in the normal first-person driving mode, called A-Spec mode. Each race event can yield up to a maximum of 200 A-Spec points. Generally, a win using a car with less of an advantage over the AI opponents is worth more points. Points can only be won once, so to win further points from a previously-won event, it must be re-won using a car with less of an advantage over the AI. There are also the 34 Missions which can yield 250 points each. Despite this, A-Spec points are experience points, not money.
