Initial D Arcade Stage/YMMV

~~Character~~ Car Tiers
Game Breaker: The Integra Type R DC2 in Ver. 2, due to it having faster recovery from crashes, which meant that it was especially viable in Irohazaka.
Most Annoying Sound: The loud Buzz/Honk while navigating the selection menus in Initial D 3

Sequelitis: Initial D 4 and Initial D 5. A sixth game is in the works for 2011.
That One Boss: Takumi when he's in the Trueno, his father Bunta in all of his appearances, and Ryousuke.

Tier-Induced Scrappy: Both versions of the ~~Miata~~ Roadster, and the AE85. Though the latter (and its driver in the anime and manga) are already in-universe Scrappies.
