Some people collect video games, but other people collect video game controllers. Consider the collection of Nintendo GameCube controllers on display at The Controller Library as maintained by Carl Synnett, for instance. You're probably thinking that if you've seen one GameCube controller, then you've seen them all. How many can there be? I mean, there's your basic wired model, and then the wireless WaveBird, and then maybe a few different color variations, and you're done, right? You've got some nerve, mister. There's a lot to see from prototypes cobbled together from spare parts to Club Nintendo-exclusive variants to specialized models used in hotels to some downright strange creations that integrate extra functions in surprising ways. There's even room in the collection for the more recent version of the controller produced during the Wii U and Switch eras for Super Smash Bros. Spend some time browsing and prepare to be intrigued.
