Long story short, it had long been urban legend that Atari buried thousands of copies of ET for the Atari 2600 after the game flopped. It's considered by many to be possibly the worst console game...ever.
Having had it myself, I can verify it was indeed awful. Worst ever? Not sure about that.
I wonder if they'll find any of the Swordquest games too?
...these are my continued thoughts on the gruesome game, Manhunt. Since I've been playing this game for a few days now I can give you some more thoughts regarding this excellent stealth/suspence 3rd person roamer.
