I played a while online last night... I think its rubbish..
The faster the cars go the worse they get, i tuned up a gt86 on racing softs and it was trying to tip over in corners.. The camera shake is shocking, the ffb is crap.. There is a heavy damped feel where everything you do feels like its lagging behind, when you loose the rear end the wheel doesnt feel no different and you just start over correcting..
I wouldnt bother getting it in hindsight.
