One of the most frustrating games we've played in quite some time. The driving and scoring models are simply unforgiving at best and broken at worst. Unless you want numerous reasons to throw your controller through your television, avoid this at all costs.
In Grand Prix, the wild-card of bad design proves too difficult to surmount. That lack of consistency, coupled with grading criteria set in the real-world instead of the game's flawed reality, leaves me with no choice but to deem this game unworthy.
