The development of the Sega CD was top secret. Game programmers were unaware of the support for which they were developing until the Tokyo Game Show 1991, where the announcement of the Sega CD made a great noise. It was the first console CD player intended for the general population. Unlike the PC-Engine (TurboGrafx-16), which already supported the medium, the Sega CD was much more accessible for the non-hardcore fans.
The machine is launched in the land of the rising sun on December 1st, 1991, for a price of 49,000 yen (about $ 200). 100,000 units were sold the first year. The high price of the Sega CD slowed down the sales in Japan and in North America.
It was difficult to create CD games for a console that, basically, was not powerful enough for this kind of support. The result was often very poor: very low quality videos with only a few colors and games with failed gamplay.
