On September 10, 2001, Akira began searching for one of the hundreds of Tetris knockoffs that graced the 16-bit Commodore Amiga in the 1980s. Or, rather, he began the public search: he'd already tested and discounted a few dozen before appealing for help. The 23-page forum thread–and the hunt–continues to this day, despite Akira's offer of a cash bounty; his or her most recent post was just a few weeks ago.
He seems dejected: "It was the best Tetris port to any system. Second place is for Gameboy Tetris and third is for Tengen Tetris on the NES. [But] I have no will to invest this much energy in a stinking game. Looking around for disks and stuff … May it be lost forever!"
