About the SEGA Genesis

The Sega Genesis

The Sega Genesis or also known as the Mega Drive outside of North America is a console that was developed and sold by Sega. It is also the successor the Master System console.

Like most of Sega’s consoles this again didn’t go to well against the two competitors the NES and the NEC’s PC Engine. It still however was able to achieve success in North America and Europe. The huge game library was one of the factors that helped the console sell well.

The Sega Genesis boasted a game library of over 900 games these were developed by Sega and also a wide range of third party publishers. The games came in form of a ROM based cartridge. The console featured games such as Sonic the Hedgehog, Disney’s Aladdin, Mortal Kombat and many more classics that we know and love.

There were a number of peripherals released for the consoles such as a light gun, a mouse, a foam covered bat and many more extra items to add extra functionality to the console. At the end of 1994 when the newer 32bit bit consoles were released the console became obsolete very fast. By the time the Sega Genesis was discontinued it had sold an estimated 40 million units.

The Sega Genesis still maintains a strong fan base with people collecting the old consoles and games. As well as people turning to emulators to replay some of the classics they grew up with.
