Though Square never brought Seiken Densetsu 3, Secret of Mana's sequel (which itself was a follow-up to Final Fantasy Adventure), to the states, a fan translation project provided gamers with a localization ROM patch in 2000, five years after its release in Japan. Even with just an unofficial translation, the cooperative ARPG is widely acclaimed by those who've played it, some even claiming it as the Mana series' apex.
As fun as Seiken Densetsu 3 is, the Super Nintendo experience just doesn't seem "authentic" unless you're playing the game with the original rounded controllers on hardware yellowed with age. This auction on eBay plays on that sentiment, offering up a "Secret of Mana 2" set which includes the patched game on an SNES cart, a mocked-up box, and an English-translated instruction booklet.
Everything about its production screams "bootleg," and counterfeit releases like these can never be trusted for their quality or reliability, but that hasn't stopped bidders from running its auction price up to $300 with 15 hours still left on the clock!
