The game is only worth going back to for its darker themes and pretty colors, its a good departure from all the other GBA titles but the gameplay really starts lacking due to a lack of difficulty.
There is zero progression/car unlocks in the game, which essentially removes about 30% of the enjoyment in a racing game. The game also does not look great when driving at night. Overall a really shallow game that never feels rewarding.
Got halfway into part 2 and it feels like Path of Radiance with a bit more of a convolution in its plot with the whole Micaiah not liking Ike thing. Dawn Brigade doesnt help either.
