Super Mario Generations is a video game developed by Bronze Piston Productions, Bluesilver Studios, and Nintendo EAD, and published by Nintendo. Sonic Generations was inspired by this game, a future game to be released in 2011, although not heard of at the time. Super Mario Generations was released to the public on September 19, 2016. This was to celebrate Mario's 35th anniversary. It was first thought to be released for only the Nintendo 3DS and a rare edition for the Sega Dreamcast, but it was released for the Nintendo 3DS and the Xbox One instead. The game sold 10 million copies by November 21, 2012. As of July 31, 2013, it has sold over 13,000,000 copies and counting.
