Forza 3 is proving to still have some mileage in its tank.
If you have not bought it yet, it is a pure infectious fun game and well worth a punt. The chaps at TGSN are hosting regular fun nights on forza, so if you want to get a few games in sign up to their forums and have a laugh.

Check out this video that Rodriquo from TGSN made of the the last fun night, which was Asian A Class Cars.
