The Sega 32X was the last add-on released for the Sega Genesis to compete with the Super Nintendo (the first was the Sega CD). It allowed the Genesis to produce 32-bit graphics.

Initially, the 32X was planned to be a standalone 32-bit cartridge-based console called the Neptune before Sega decided to make it an add-on for the Genesis.

Why It Flopped

  1. Like the Sega CD, it had its own power supply, requiring a total of 3 AC cables to use it (2 from the console and 1 from the TV), 4 if you also have a Sega CD. These AC cables also have huge boxes so they take up a lot of space and make them harder to plug at once.
  2. You need special metal prongs to attach it to a model 1 Genesis.
  3. It requires another cable to connect it to the Genesis, which makes no sense because it's already plugged into the Genesis.
  4. Only 40 games were made for it and virtually none of them were good.
  5. It had a very expensive launch price of $159.
  6. The main reason it failed was that the Sega Saturn was due to be released six months later, making it nearly pointless to own one.
  7. It had many technical problems, like being able to mess up Genesis games.
  8. There were no proper Sonic games for the system aside from Knuckles' Chaotix (if it counts as one).
  9. Terrible marketing with innuendos.

Redeeming Qualities

  1. To be fair, it DID have some good games, such as Virtua Fighter, Tempo, and Knuckles' Chaotix.  


The add-on failed miserably with only 660,000 units ever sold and only 40 games made. The Sega Saturn was released just six months after the 32X (and was already out in Japan), so most gamers chose to ignore the 32X and just wait for the Saturn or the Sony PlayStation.

James Rolfe (in his Angry Video Game Nerd persona) described the 32X as the Genesis "being on life support" due to the massive number of cables on the back of the console when the 32X is plugged in.

The massive failure of the 32X was one of the major factors to Sega flopping as a console developer and be forced to become a third-party developer. Sega was heavily criticized for releasing too much hardware too quickly. Many developers would later refuse to make games for Sega, as they kept cycling out their consoles. The terrible financial losses and loss of trust from third-party developers caused by the 32X went on to affect the Saturn and Dreamcast as well, causing both consoles to fail.
