The input for the controller is WAY WAY to sensitive. It takes little to no pressure to hit full throttle or brake. This was a problem in GT 4 as well IMHO but it was easily fixed by bashing the poo out of the gas and brake button until you "desensitized" it, but at like 50 bucks for a 6 axis I'm not gonna do that for GT 5. I tried remapping the gas and brake to the L2 and R2 buttons but its still almost impossible to input anything less than 50%. The steering is also a bit touchy initially, and makes some cars like the EVO X feel very twitchy. I know someone is gonna say get a wheel, I have a DFP but i use that for GTR-2 on my PC. I've always preferred a controller on GT. When I want to play a full blown Sim that requires a wheel i play GTR. If they want to make GT like that, fine what ever, but either remap the inputs so its possible to play effectively with out aids, or give me the ability to set the input curves my self.
