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.

Sega scaled down and adapted their Sega System 16 (used to power arcade hits like Altered Beast and Shinobi) into the Mega Drive (sold as the Genesis in North America) and released it with a near arcade-perfect port of Altered Beast. Sega's console met lukewarm sales in Japan, but skyrocketed to first place in PAL markets, and made major inroads in North America. Propelled by its effective "Genesis does what Nintendon't" marketing campaign, Sega capitalized on the Genesis's technological superiority over the NES, faithful ports of popular arcade games, and competitive pricing. The arcade gaming company SNK developed the high end Neo Geo MVS arcade system which used interchangeable cartridges similar to home consoles. Building on the success of the MVS, SNK repackaged the NeoGeo as the Neo Geo AES home console. Though technologically superior to the other fourth-generation consoles, the AES and its games were prohibitively expensive, which kept sales low and prevented it from expanding outside its niche market and into serious competition with Nintendo and Sega. The AES did, however, amass a dedicated cult following, allowing it to see new releases into the 2000s. Fourth generation graphics chips allowed these consoles to reproduce the art styles that were becoming popular in arcades and on home computers. These games often featured lavish background scenery, huge characters, broader color palettes, and increased emphasis on dithering and texture. Games written specifically for the NES, like "Megaman", "Shatterhand", and "Super Mario Bros. 3" were able to work cleverly within its limitations. Ports of the increasingly detailed arcade and home computer games came up with various solutions. For example, when Capcom released "Strider" in the arcade they created an entirely separate Strider game for the NES that only incorporated themes and characters from the arcade.
