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.

In Brazil, where the Genesis never ceased production, Tectoy released a portable version of the Genesis with twenty built-in games on December 5, 2007. Another Tectoy variant of the console called "Mega Drive Guitar Idol", released in 2009 in Brazil, includes two six-button joypads and a guitar controller with five fret buttons. That year, AtGames began producing two new Genesis variants in North America and Europe: the Firecore, which can play Genesis cartridges as well as preloaded games; and a handheld console, the Sega Gopher, as well as a dedicated motion console, the Sega Zone, preloaded with 20 Genesis games. Companies such as Radica Games have released compilations of Genesis games in "plug-and-play" packages resembling the system's controller.
