I did not that much fun for a while. I do not regret having to buy a Xbox to try this game out.
The driving feeling is a blast. When you drive a powerfull rear wheel drive, you can finally do donuts, power slides and drifts by playing with your accelerator input. Front wheel drive such as the dreaded little CRX-i, queen of the lowest class, have their share of fun too.
Less car than GT4, but still a wide range from the Muscle cars, to my favorite old classics (GT2000, James Dean's Porsche, vintage Ferraries), to the comon ricers wanabees, to the Supercars ending by Gts and GT-Rs classes and the Audies R8s alike. Afterall, when is the last time you drove a Midget or a 1875 Benz in GT4?

Most of the cars are tunable, including the body parts. Your goal is to build a car for a specific class. Classes are mostly based on power to weight ratio, giving you a lot of liberty to tune your car with the appearance, but also the handling performances within your class. Classes are D (think HOnda civic), C, B (GTO, camaros), A( viper/porsche/vette type), Supersport (S7, F50 type), GT, GT-R.
The best of the game being
Online play, as much fun that GT4 Challenge was, runing for the best qualifying time cannot be compared with a full 8 people race, scortching each other for a couple of laps. Add a forgiving damage model, severe enought to alter your performances when you screew up, and you have a good clean fun online racing game.
A few features that I miss from GT4, but they are mostly cosmetic, for me driving a car who's not glued to the road thx to supertires and being able to recover wrong turn entry with a skillfull powerdrift is the way to go.
Oh ... and there's no licences to pass in Forza
Waiting for some AHers to start a league.
