Nintendo GameCube Controller, Indigo

The buttons on the right side are arranged so that the A Button home position may be set by the player, making the role of each button more intuitive. There is also an even wider variety of controller operations. Now you can choose from an actual analog trigger on both the right and left, as well as a second analog control stick. And if all of that is not enough, the rumble function is implemented into the controller itself, thus eliminating the inconvenience of inserting and removing a separate rumble accessory or replacing batteries.
