I've been gaming for almost 30 years. I got this game to play with my 7yo. Even on the easiest difficulty, it is *unbelievably* difficult. The racing itself is stacked against the player (you always start in last, despite the results of your previous race) and the green team *always* finishes together, so you better be 1st and 2nd because your CPU teammate is worthless and the rival team will absolutely be 3rd, 4th, and 5th.
The drifting challenges are beyond difficult to the point of being almost impossible. We're on chapter 6 now, I doubt we'll finish the game.
