Sega Mega CD

One of two very much unneeded add-ons for the excellent mega drive that was too expensive at launch, had few classic titles and was seen by many as a massive failure which had damaged Sega's reputation which resulted in the failures of the Saturn and then the Dreamcast. It was technically superior to the mega drive however which meant that some of the games looked better, even those ported from the mega drive such as Ecco the dolphin and Chuck Rock which had much better music as well and when sonic CD is played compared to the mega drive sonic games, you will see just how much better a simple mega drive game can be, with its amazing tunes being the main thing. Overall though, it is not recommended as there were not many games and of those that were relesed the vast majority were ultimately unplayable.
