Wait, how do Jeff and Alex hate the Gamecube controller? It's the best fucking dual analogue controller in existence. Every button in uniquely shaped, easily identifiable, and quick to reach with your thumbs. All a newer version would need is a left Z button a clickable sticks and no one would ever need to make a new controller again.
I hate the Gamecube controller. One of my least favorite controllers in the world.
Still leagues better than the N64 controller.
