Did you know that the Sega Genesis (nee Mega Drive) version of Alexey Pajitnov's Tetris is exceedingly rare? That there are reportedly only about ten copies of this cartridge in the wild? Then you're probably not in the market for a million dollar copy of Tetris.
Alexey Pajitnov, creator of Tetris, may be semi-retired these days, but he still likes to dabble in a bit of game design from time to time. At the moment, for example, he's working on multiplayer Tetris.
With more than 125 million copies sold on more than 30 platforms, Tetris is rolling into its 25th Anniversary with a bright future.
