This is an alphabetical list of released games for the Genesis. Titles listed do not include releases for the Sega CD and Sega 32X add-ons. Included in this list are titles not licensed by Sega, including releases in Taiwan by several developers such as Gamtec, as well as releases by Accolade before being licensed following the events of Sega v. Accolade. This list also includes titles developed by unlicensed third-party developers after the discontinuation of the Genesis, such as Pier Solar and the Great Architects.
A few games were released exclusively on the Sega Channel subscription service; which was active from 1994 to 1998. This means that no physical cartridges were officially released for use on consoles. While few games were released this way, some of them are considered to be staples in the Genesis library, such as Pulseman and Mega Man: The Wily Wars. These titles have been specified in the list with their release status on a yellow background.
