Game modes • Career mode returns from previous games in the series. The player takes control of a custom driver and races to get sponsors, equipment for his or her garage, and respect from other drivers. • Season mode allows players to take control of either a custom driver, or an existing driver for a season or more, with custom rules and schedules. • SpeedZone is a mode in which players can hone their skills in passing, blocking,
drafting, as well as
time trials. • Lightning Challenge is a mode in which the player takes control of a driver and race in a situation that occurred in the
2002 Winston Cup and
2003 Winston Cup seasons to that particular driver. It also includes a video with
Michael Waltrip as the reporter, and beating these challenges unlocks new Thunder Plates, which unlock new tracks, fantasy drivers,
Busch Series drivers from the
2003 season, as well as legendary drivers. • Another new game mode is Online mode, where players can race online if they have an Internet connection and adapter. Microphone support also was available on PC and PlayStation 2. This feature is not available on Xbox and PS1. • Thunder License, a tutorial mode featuring NASCAR legend
Richard Petty, in which the player chooses a driver and follows him along a
racing line around the track, with voice commentary by Petty. The racing line can also be toggled in Race Now mode.
Grudges and Alliances feature The main feature of the game is the "Grudges and Alliances" feature, which is based on the player's driving style and attitude. If the player drives dirty and bumps into other drivers, even if it was an unintentional bump, that driver becomes a "Rival", and will bump into the player if they happen to encounter each other later in the race. However, if the player
drafts the opponent (a new feature for the game), that rival's level in grudge severity drops. If the player drafts a neutral driver long enough, that driver will become an "Ally", and at times will let the player pass. Conversely, if the player bumps into an ally, their alliance will slowly drop. The maximum severity value for both grudges and alliances is -100 and +100, respectively. Players can see their four highest grudges and alliances at the end of the race. In Season and Career modes, the grudges and alliances the player makes carry over to future races. ==Reception==
