Ferrari Challenge promised a lot but delivered very, very little and early owners of this game amounted to nothing more than beta testers who had to pay for the privilege.
I'll start with the good, the driving physics are rather accurate and the track selection is lengthy and diverse, even if some of the circuits are a bit inaccurate. The inclusion such world class circuits like VIR and Spa was especially welcome.
Despite gritty and low rez graphics, the game has a low and inconsistent frame rate and is rife with popup. It completely fails in conferring a sense of speed, an attribute any racing game should posses.
Opponent AI is equally lackluster, consisting of nothing else but remorseless blocking that allows cars ahead to escape. The behavior exhibited by the AI would be promptly black flagged in any amateur or professional race series on earth.
If that were not enough, the game as delivered, featured completely broken online racing that was fixed for MONTHS. In addition, PROMISED DLC has been scuttled because of "licensing issues", but curiously these issues don't prevent the DLC from being rolled into a new game from System 3, called "Supercar Challenge".
Don't buy this game. Don't reward these developers' lies and deceit with you hard earned gaming dollar. Gran Turismo 5 prologue, while not without issues, offers a MUCH better racing experience and MUCH better value for your dollar.
