Sell your GameCube games for cash.

Nintendo’s fourth home console, launched in Japan in September 2001 (codename: Dolphin) and North America that November. It was the company’s first system built around optical media instead of cartridges: an 8cm mini-DVD disc capped at 1.5GB, plenty of room for the era but too small to double as a movie-DVD player like its PlayStation 2 and Xbox rivals. The cube shape and built-in carrying handle gave it real character, though critics at the time joked it looked more like a lunchbox than a game console.

What it lacked in sales volume, it made up for in library. Super Smash Bros. Melee is still the GameCube’s best-seller at over 7 million copies. Metroid Prime marked Retro Studios’ debut, a brand-new Western studio handed the unenviable job of following up Super Metroid, and it delivered. Eternal Darkness: Sanity’s Requiem remains one of the only Mature-rated games Nintendo’s ever published outright, and the Pikmin series started here too.

It’s also Nintendo’s third-worst-selling home console of all time, ahead of only the Virtual Boy and Wii U. That modest print run is exactly why a clean GameCube library is worth tracking down today: discs that didn’t ship in huge numbers, controllers that took a beating, and memory cards that are easy to lose track of in a drawer.
