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.

For his part, Kalinske highlighted Sega's role in developing games for an older demographic and pioneering "the concept of the 'street date'" with the simultaneous North American and European release of "Sonic the Hedgehog 2". John Sczepaniak of "Retro Gamer" noted, "It was a system where the allure was born not only of the hardware and games, but the magazines, playground arguments, climate, and politics of the time." Sega of America's marketing campaign for the Genesis was widely emulated, influencing marketing in the subsequent generation of consoles.
