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.
Madden NFL
EA reverse engineered the console to sell the game without paying the standard $8 to $10 license fee per cartridge to Sega, then proposed a compromise of $2 per cartridge and a $2 million cap on the fee. The console maker agreed, afraid that EA would sell its reverse-engineered knowledge to other companies; the agreement saved EA $35 million over the next three years. As its own Joe Montana-endorsed football game would miss the 1990 Christmas shopping season, Sega asked EA to let it sell "Madden" with the Montana name. EA refused, but offered an inferior alternative that lacked "Madden"'s 3D graphics and most of its 113 plays. "Joe Montana Football" sold well despite shipping after Christmas 1990, and remained popular after BlueSky Software took over development. "John Madden Football" for the Genesis, however, became both the first hugely successful "Madden" game—selling 400,000 copies when the company expected 75,000—and the first killer app for EA and Sega, helping the console gain market share against the Super NES. From 1992 to 1994, "Mega" placed the game at #1 in their monthly Top 100 Mega Drive Games of All Time.
