The 15 Rarest Nintendo GameCube Games – SlashGear

If you grew up in the ’90s, it’s likely you had a Tamagotchi or two. If you didn’t, you probably had one of the dozens of copycat toys which offered a version of the same experience. While Tamagotchi was the reigning champ of digital pets at the turn of the millennium, Digimon was close on its tail, and for good reason. After launching Tamagotchi, the toymakers realized it wasn’t as popular among young boys, so they repackaged the toy with monsters and called it Digimon (via CBR).

Those digital monsters have since broken out of their plastic casings to inhabit cartoons, video games, and more. And in 2004, the franchise made its way to the GameCube with “Digimon Rumble Arena 2.” Unlike other Digimon games, this one isn’t about collecting creatures and battling foes one at a time. Instead, it takes a battle royale approach similar to “Super Smash Bros.” in a last ‘mon standing contest.

The game got mixed reviews at launch with some critics recommending you rent it, while others suggested skipping it altogether. But Digimon has a fervent fanbase that persists to this day, allowing even an average title to retain popularity among collectors. Today, you can get a used copy for a few hundred dollars, but a factory-sealed copy goes for upward of $850.
