> That is hardly relevant, using a stick as position input would give you, what, five units of movement on either axis?
From what I can find online, the PS3 controller is 10-bit per axis (1024 positions on either axis), the Xbox 360 is either 8-bit (256 positions) or 16-bit (64k positions.)
A 25-way joystick of the type you describe wouldn't be usable for most console games, whether as a position or velocity input.
