The Sega 32X (codenamed Project Mars during development), was an add-on for the Sega Genesis released a few years after the Sega CD, releasing in 1994 in Japan and the United States, and 1995 in Europe. The add-on was created as essentially a stop-gap between the release of the Genesis and Sega Saturn, being a lower-cost option for people who wanted to play 32-bit games but not being able to afford the leap to the Sega Saturn. However, third-party developers didn't pay it any attention due to the Sega Saturn already having launched in Japan by the time it was released in the United States, and most consumers opting to just wait until the Saturn launched. Regardless, Sega and some third-party devs still developed games for it, some of which taking advantage of the system's 3D graphics capabilities, as seen with the port of Virtua Fighter, Virtua Racing Deluxe, and Darxide. Some of the system's most notable games (out of a library of only 40 games) were Knuckles Chaotix, Doom, and the aforementioned Virtua Fighter. The 32X sold less than 1 million units and was discontinued in 1996. While initial reception was somewhat positive, later reviews were much more negative, with it being considered one of, if not the reason Sega ended up dropping out of the console market, due to its shallow library of games, the lack of quality or standout titles, poor timing, and market fragmentation of the Genesis.
