Degenatron

Degenatron is a fictional game console that's advertised in Grand Theft Auto: Vice City. It was a low end games console which came with 3 games. They were not considered very good and struggled with much better competition from the home computer market. This is mostly like a parody of Atari 2600. The 'GEN 2' was launched in 1991 but the company vanished a year later.
