I tried it for a couple of hours last month with the Fanatec. I was racing a BTCC series over at TORA so ran round Road Atlanta my usual FWD Avensis. Was hoping that the FFB on the wheel would help. Unfortunately not. The knife edge handling was still there - Grip, Grip, Grip, No Grip, Crash! The FFB was a complete disappointment after the PC titles.
I don't tend to play single player, just jump online with real douchebags. I didn't find it that bad ... then again I've got a friends list full of people who used to league race Forza 3/4/5 so they're pretty well behaved. The rubber banding was pretty bad at first though.
Power of the cloud, drink the Beardy Dan Kool Aid!
Typical Forza. You get used to it!
