For all of the hullabaloo its generated with its tiny consoles, Nintendo didn't invent retro gaming consoles. Not by a mile. When it released the NES Classic late last year, Nintendo wasn't creating a new field of consoles fuelled by nostalgia and the fat wallets of ageing Gen Xers. Rather, Nintendo was reinventing the retro console, which has long existed as a series of crummy knock-offs. AT Games was one of the purveyors of those crummy consoles -- churning out Sega Genesis and Atari 2600 clones that cost next to nothing and often times felt like they played even less.
