Highly underrated game, a worthy rival to Need for Speed Underground. No other arcade racing game had this many mechanics: a proper damage model, crew races, a stunt mini-game, betting (with the opponents getting stronger if you bet against them), an event calendar, used car dealerships, a selection screen for frickin' flip phones for calling rival crew members... Not every mechanic is great, but it all adds up to a very immersive experience.
In particular I remember the stunt mini-game being my first introduction to the differences between front-wheel drive, rear-wheel drive, and all-wheel drive handling. Each type of car has a very unique feel to it, much more so than in other racing games at the time.
