edit: You don't need a wheel to drift....BUT I find the game 100000 times more enjoyable with a wheel. They designed the DFP along with gt4...so why not use it? I think the DFP should be considered as the True oem controller for GT
Honestly , a wheel is no way near crucial or even important to a good GT4 experience. You can easily drift with the analog sticks but with something like LFS you'd need a steering wheel because you REALLY need the smooth inputs.
just answer this.
Gt4 is the real driving simulator, but do you actually drive your every day car with a joystick?
So how can you enjoy it without a wheel?
