My GamePad still works perfectly as it did from day one but given that now I rarely use it due to the Wii U Pro Controller that's no surprise, still, the screen's got a lot of light scratches (not really noticeable) because of always using the stylus so it was bound to happen.
I could've used a screen protector for the GamePad's screen but honestly the tech's old and it probably works better without it.
yea, some games are mandatory with the gamepad, kirbys clay curse is 100% gamepad. Also in order to change system settings you also require use of a gamepad
ThanksYeah, they're universal as long as you unsync it from the previous console
