I have to respectfully disagree!
I have found the FFB in S2 to be better than GT5, every single time I hit the curb or grass I can feel it through the steering wheel, same with loss of traction and wheel spin...as I already mentioned too, I can even feel the change in transmission through the wheel.
My experience with Shift 2 was using a copy on the XBox 360 with a Fanatec TurboS wheel. basically the major issue was the FFB was horrible.
Example. I jump in a stock tuned mediocre road car and take it to the track. My wheel is set to the same thing I would normally use for Forza. So I start to drive and at first it feels ok, steering is nice an tight until I start to move then once I reach a few mph there is no feel of the road at all, it is so bad that I can not even feel the center and almost impossible to even drive in a straight line. Yet if I hit a curb or drive off track then the FFB kicks in hard but absolutely no feel of the road.
I tried a lap around Nurburgring in I think it was a GT3 BMW or something like that and I must have been off track around 70 times due to the horrible feedback on the wheel. Never have I experienced something that felt so bad even the old non FFB spring wheels felt better than that POS
Eventually I played around with all the various wheel settings and manged to at least get it to where you could feel the center and drive straight then I did another lap around the ring and got a clean lap with about 75 perfect corners according to the game but it still did not feel anywhere near as good as Forza or GT.
The end result was that the game hit the shelf and began to collect dust never to be played again.
My brother had both the XBox version and the PC version and told me the PC version did not feel nearly so bad in fact he actually picked up the Xbox version after having played the PC version briefly. He got the Xbox version so we could race online together but after about 30 minutes he had enough and tossed it.
I have no idea how it feels on the PS3 but I would never waste a dollar on it to find out, it really was that bad. A couple of my friends have it on Xbox and they actually recommended it but I guess they had been smoking something that had them in an altered state or something.
If you like it that is fine but for me it is nothing more than garbage.
