Looks Great, plays bad
Tracks - now ok you only get six but they could have picked more fun tracks to drive around. Poor selection imo.
Physics - They realised you could drive around some corners and deliberately crash into the barrier and let it take you around the corner faster than if you took the racing line! You can also take short cuts. Unfortunately the fix is worse. Now you get a 4 second penalty for hitting the barrier or taking a shortcut. So i f you are online you could get bumped into the barrier and receive a 4 second penalty (you can't accelerate) without it being your fault! When you mix this with laggy online games (16 players promised on the box but capped at 12) and cars going into ghost mode when they swerve and then going solid again just as you try to drive through them it is really frustating.
When you compare this game to Forza Motorsport 2 (I have now gone back to this great game for my motorsport fix) you realise how far the series has fallen behind. I will probalbly not get GT5 if this is the standard and just wait a little longer for FM3.
