Sega Genesis
30.75 million first-party Genesis units were sold worldwide. In addition, Tec Toy sold an estimated three million licensed variants in Brazil, Majesco projected it would sell 1.5 million licensed variants of the system in the United States, and much smaller numbers were sold by Samsung in South Korea. By the mid-2010s, licensed third-party Genesis rereleases were still being sold by AtGames in North America and Europe. Many games have been rereleased in compilations or on online services such as the Nintendo Virtual Console, Xbox Live Arcade, PlayStation Network, and Steam. The Genesis was succeeded in 1994 by the Sega Saturn.
Sonic the Hedgehog 2
Due to the popularity of its predecessor, "Sonic the Hedgehog 2" already had an established fanbase anticipating its release. The game received critical acclaim and was a bestseller in the UK charts for 2 months. As of 2006, the game had sold over 6 million copies, making it the second best-selling game for the Sega Genesis (after the original "Sonic the Hedgehog").
