A popular series of competitive racing games for the arcades by Creator/{{Sega}}, based on the manga and anime series ''Manga/InitialD''.

Currently the latest installment of the series is ''Initial D Arcade Stage Zero'', or ''Initial D Zero'' in short, which is the latest installment of the series. There also have been a few console releases, though in Japan only: ''Initial D Special Stage'' for the UsefulNotes/PlayStation2 (based on ''Initial D Arcade Stage Ver.2''), and ''Initial D Extreme Stage'' for the UsefulNotes/PlayStation3 (based on ''Initial D Arcade Stage 4'').

Compare and contrast ''VideoGame/WanganMidnight''.

!!These games provide examples of:

* BattleAura: Get enough wins and you'll get one, with the color changing as you get more wins. If you have the second-to-best aura, a white aura, and get enough consecutive wins, you'll earn a [[CosmeticAward rainbow aura]]. Break your win streak and it reverts back to white. However, this, along with other features, has [[BadExportForYou disappeared]] from the English-language version of ''4''.
** [=6AA=] brought this back (level the card up enough to get them), but you still have to play online mode to get two of the top auras.
* DamnYouMuscleMemory: Players used to other racing games will generally have a tough time getting used to ''Arcade Stage'''s gameplay, especially if they're fans of the simplified slides of ''VideoGame/RidgeRacer''-esque games; it doesn't help that for a series famous for drifting, for the first few versions of the game cars technically can't even drift. The series itself exhibits this as well, with changes between versions ranging from slight differences in car handling, completely new physics engines, and even the location of the physical shift knob on the cabinet.
* FinalBoss:
** DiscOneFinalBoss: Takumi, in every single ''Arcade Stage'' installment.
** TrueFinalBoss: Bunta. He challenges you to a free battle only if you have cleared all rivals in one loop of Legend Of The Streets mode. Whether you win or not, the credits will roll afterwards.
* DifficultButAwesome:
** The Suzuki Cappuccino is one of the most difficult cars in the game to master, with one of the worst acceleration in the game, and it oversteers like crazy. However, it was also the lightest and fastest, and once mastered, can beat every single car in the game in terms of setting fast times.
*** The Cappuccino ended up becoming a [[JokeCharacter Joke Car]] after loads of nerfing in ''7AAX''.
** The Mazda RX-8 in "Version 3". It understeers, but also drifts at the same time. Said vehicle has also been used to set the world records on both directions of Shomaru, one of the hardest courses in the game, and also is the highest ranking vehicle OVERALL in that installment. The RX-8 sits at mid-tier in later installments, however.
* DifficultySpike:
** Tsuchisaka Outbound in ''Version 3'' starts off fairly simple from the start right up to the end of the long straight tunnel to a literal ''rollercoaster'' section from there to the finish line.
** Tsukuba in ''4'' and ''5'' goes from "fairly nice and easy" in sections 1 and 2 (assuming you're going outbound) to "{{oh crap}} what the hell is this" in sections 3 and 4.
* EasyModeMockery: Using automatic transmission on most tracks won't get you record times. The game's AT doesn't shift at the ideal shifting points either.
** Worse yet, if you're using a card, you can only change transmission on card renewal, which is every 50 plays. In Initial D 4 and 5, you pay to change transmission, which makes more sense from a realistic point of view but is still kinda annoying.
* ExtremityExtremist: The [=AE86=]'s forte is downhill racing. The RX-7's forte is uphill racing. Both the FC and FD RX-7s excel in dry conditions, while the GT-Rs dominate on wet pavement. The Celica GT-Four and other 4WDs that would normally understeer excel on Akina Snow, but can still be very difficult to handle.
* GenrePopularizer: Though not the first of its kind by a long stretch, it's ''the'' game that brought the multiplayer arcade racing game scene to competitive levels on a worldwide scale.
* GreenHillZone: Myogi in ''Initial D Arcade Stage'', Lake Akina in ''4'' and ''5'', Usui joins in in ''6AA''.
* InterfaceScrew: In a versus battle, if one player turns off their car's lights, the other player's "Advantage" (distance ahead/behind opponent) meter will be disabled.
* JackOfAllStats: The Mitsubishi Lancer Evolutions and Subaru Impreza WRX [=STis=] are both newbie-friendly and can take on all tracks in any orientation decently... just don't expect to set course records outside the home courses.
* [[JokeCharacter Joke Car]]: The [=AE85=] Levin and the Prius; averted that performance-wise it is not really that different than the others.
** Some skilled players [[CherryTapping capitalize on its reputation]], though.
*** And now, the Suzuki Cappuccino joined the group in ''7AAX''.
** The Honda Civic [=EG6=] was also this in the first game.
* NintendoHard: [[TrueFinalBoss Bunta Challenge]] in Ver. 2 and 3.
** Shomaru in Version 3 and Special Stage. The single-lane road makes passing opponents extremely difficult. In addition to that, it has very few straights, if any, at all, making for a grueling racing experience, especially in vehicles that suffer from bad understeer, yet the Mazda RX-8 managed to become THE fastest vehicle on either direction of this course.
* NoBackwardsCompatibilityInTheFuture: ''4'' doesn't allow data transfer from cards used in older versions, forcing players to make a new card from scratch. This was due to it being a complete overhaul instead of a simple upgrade.
** Downplayed with ''Zero''; only car data aren't transferred when you transfer old data from ''8 Infinity''.
* RecurringBoss: Takumi in Legend Of The Streets Mode. He first appears as a WarmUpBoss on Myougi (Ver. 1-2) or Lake Akina (4 and 5), then later he races you for real on Akina, then he becomes a FinalBoss on the last course of the game.
** In [=6AA=]'s Legend arc, Takumi can still be considered this since he is consistently on the higher level of difficulty while the other racers (Rin, Ryousuke, even Bunta) is not.
* RubberBandAI: The "boost" feature. Often turned off in human vs. human matches.
* SpiritualSuccessor: It was somewhat related to ''VideoGame/SegaRally''.
* ToneShift: Prior to ''Zero'', the games used artworks based off anime and manga's styles. However, ''Zero'' picks in the new style employed by the three-part ''New Initial D The Movie'' series. ''Zero'' also uses Japanese rock songs used in the movies, instead of usual Eurobeat as in previous installments and episodic anime series.
