Mega Man 6 was the final entry in the Classic series to be released on the NES. The NES was deep into its twilight years, and as such, Capcom opted not to publish the game in the West; instead, Nintendo took up publishing duties. Rockman 6: The Greatest Battle of All Time!! was released in Japan in October 1993, while Mega Man 6 was released in March of 1994, three months after Mega Man X blasted its way onto the Super Nintendo. Mega Man 6 was not released in Europe until 20 years later on the Nintendo 3DS Virtual Console.
