The GameCube controller, which turns 25 this year, remains one of the most fondly regarded gamepads among Nintendo fans, prompting the company to keep official support for it alive on every home console since. Its enduring appeal stems from a distinctive design tailored to GameCube-era games, its deep association with the Super Smash Bros. franchise, and the fact that its game library has continued to be playable on later Nintendo systems, including the Switch.

Unlike the standard four-button diamond layout, the controller features an oversized green A button, small red B button and kidney-shaped X and Y buttons, making it easy to identify buttons by feel, while its analogue L and R triggers allowed nuanced control in titles such as Super Mario Sunshine. Its octagonal control-stick gate, inherited from the N64 pad, gave players precise directional input, benefiting games like Super Monkey Ball and Soulcalibur II. The controller's link to Super Smash Bros. Melee, the console's best-selling game and a mainstay of competitive play, cemented its legacy; Nintendo later released adapters so it could be used with Super Smash Bros. games on Wii U and Switch, and it remains easy to obtain and use today.
