List of Sonic Team games
In addition to the "Sonic" series, the company has developed other games for Sega, such as "Nights into Dreams" (1996) and "Billy Hatcher and the Giant Egg" (2003). The 1991 release of "Sonic the Hedgehog" is considered significant in video game history, as it increased the Sega Genesis's sales and Sega displaced Nintendo as the leading video game company. Some of Sonic Team's games, such as the Genesis-era "Sonic" games and "Nights", are considered by critics to be among the greatest video games ever released.
List of Sonic the Hedgehog characters
The "Sonic the Hedgehog" video game franchise began in 1991 with the game "Sonic the Hedgehog" for the Sega Genesis, which pitted a blue anthropomorphic hedgehog named Sonic against a rotund male human villain named Doctor Eggman (or Doctor Ivo Robotnik). The sequel, "Sonic 2", gave Sonic a fox friend named Tails. Shortly afterward, "Sonic CD" introduced Amy Rose, a female hedgehog with a persistent crush on Sonic, and "Sonic 3" introduced Knuckles the Echidna, Sonic's rival and, later, friend. All five of these have remained major characters and appeared in dozens of games.
