This is a nice video from ReplayRetro looking at the Atari 5200 console. The video goes into the history of the system and also does a bit of a review of the system and a couple of games. Worth watching if you're interested in the system.
There's no denying that the Atari VCS left a huge mark on video game history and it's probably one of the most important consoles of all time, but with such a huge amount to live up to how could Atari ever follow it up? This is the story of the ill fated Atari 5200, a console doomed to live in the shadow of its predecessors success.
