Awesome game, overall, but definitely NOT for beginners or casual racers.
The Career Mode is especially challenging for those who don't enjoy racing in EXTREMELY bad weather conditions, since there's no way to "turn off" the monsoon-like rains that often come without warning.
Seriously, you'll be at 1/2 throttle, for MOST of the duration of the rain races. And while driving an incredibly fast, finely-tuned race car reeeeeeally slow in the rain may be more "realistic", I don't consider it all that much fun.
Everything else, though, is top notch. Certainly in the top tier of sim-racing games for consoles.
For what it's worth, I race with the G29 wheel.
