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.
Sonic &amp; Knuckles
For the series' twentieth anniversary in 2011, Sega released "Sonic Generations", a game that remade aspects of various past games from the franchise. A remake of the Sky Sanctuary stage was made for the Xbox 360, PlayStation 3, and PC versions of the game, while the Mushroom Hill level was remade for the Nintendo 3DS version of the game. "Sonic & Sega All-Stars Racing" features a track inspired by the Death Egg as downloadable content along with the Metal Sonic character. The sequel, "Sonic & All-Stars Racing Transformed", featured the same race course, and an additional new one inspired by the Sky Sanctuary stage. Re-imagined versions of the Flying Battery and Lava Reef stages, along with the Blue Sphere bonus game, appear in the 2017 game "Sonic Mania".
