Sonic The Hedgehog 2 Game

In 1992, Sonic the Hedgehog 2 was released as a Sega Genesis video game. Since Sonic was the only character in the original game, Tails joining in to assist Sonic made this game special. Sonic the Hedgehog 2 allowed you to play as both Sonic and Tails at the same time, which was revolutionary for its time. In Super Mario Bros, you had to control Mario and Luigi separately.
