The Sega CD, an add-on peripheral for the Sega Genesis, expanded the capabilities of the 16-bit console by allowing it to play CD-ROM based games. This opened up new possibilities for developers, who could now create games with larger file sizes, more complex graphics, and CD-quality audio.
The Sega CD library is home to a number of classic games, including Sonic CD, Lunar: The Silver Star, and Snatcher. These games showcase the unique capabilities of the add-on, and offer experiences that are not possible on the Genesis alone.
