The Sega Genesis
, also known as the Sega Mega Drive
, was released in 1989, and quickly grew to become Sega's best-selling console system. Boasting 16-bit graphics, the Sega Genesis had three different primary models of it released, two of which used their own special RF adapters, which can be difficult to find in modern times. Several add-ons to the video game system itself were also released, including the Sega CD and the Sega 32X adapter. All of these things were able to connect together to form one large system.
Sega Genesis games were extremely popular, so vast numbers of the game cartridges were made. As a result, in modern times, prices on these games are often quite low, especially with sports games... The Sega Genesis has numerous sports games for it that, in modern times, are all worth only $1, due to the sheer number of them that were originally made.
