Griffin McElroy of Joystiq review’s Burnout Crash:

But sometimes, that hard work doesn’t matter. Forget the fact that your only mode of locomotion (exploding) scatters your defenses; sometimes, cars in your pile-ups will explode, starting a chain reaction that’s fungibly rewarding but leaves you completely unguarded. Well-intentioned power-ups do this too, like the Sinkhole, which sucks cars down a pit in the middle of your level, leaving the roadway completely uncluttered for the wave of cars that follow.

The whole review reeks of frustration with the game modes/mechanics. It’s too bad because this game sounded fun.
