GamerFitNation: In south hall at CES 2013, it seemed to be a hub for health and video games. What better location for GamerFitNation to hang out in!? While we were there we ran into an old school device with new school flavor. Meet the Retro Duo or as I like to call it the real game boy. The retro duo is device that brings old school gaming to a new school of gamers. You can play old Nintendo, Super Nintendo, or even Sega Genesis games via an attachment on it. Its an absolute pleasure to play and although it does look albeit big, it is still a device that you will have a lot of fun with.
