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.
Sega Technical Institute
Sega Technical Institute (STI) was an American development division of Sega. Founded by Atari veteran Mark Cerny in 1991, the studio sought to combine elite Japanese developers, including Sonic Team programmer Yuji Naka and his team, with new American talent. STI developed a number of "Sonic the Hedgehog" games, as well as other games for the Sega Genesis, before it was closed at the end of 1996.
