Sonic the Hedgehog (1991) is Sega’s most successful game ever. It had already sold over a million copies as a standalone release before two Sega executives approached the developer’s then-president with the idea of bundling the title with the Mega Drive/Genesis. As of September 2013, the game has shifted more than 13.67 million units, and Sega has outsold Nintendo in the West for the first time.
