This game is incredible. There's so much event and car variety, the customization is great, and the controls and handling are fantastic. The art style is just something to die for; just the addition of head and tail/brake lights is such a big contributer to the believability of it all and the shaded graphics are incredibly well-done.
Sincerely hoping this game continues to be updated at some stage. More World Race/Acceleracers realms in particular would be absolutely stunning in this game's style, even if they lack the track hazards/gimmicks and stick to being normal tracks. Highway 35 and the Acceleracers courses are so underused everywhere else.
