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.
