since the general rule of thumb seems to be that Sony started some kind of standard with their "dual analog stick" type controller. I thought of a great idea for a new controller, which I think would be ideal for FPS games. why not replace both sticks with 2 track-type balls. Or even if it just had 1 trackball and 1 stick. This would give the gamer much more accuracy and freedom than the slow analog sticks. (im assuming that the only problem with this is that the ps2/games arent programmed so support an endless rolling type input device.) but, I think this would be an awesome type of controller, if it worked properly, and would solve the age old problem of FPSers wanting keyboard/mouse (mainly because the mouse is so quick and accurate when aiming etc.) any thoughts?
