First comment reeks of "I suck at this, so it's bad". Get a time under 6.00 then tell me honestly ET is the better game.
I would normally not even respond to your second comment, but since now it's fair to say I know you: Home Run, Bowling, Activision Ice Hockey and Tennis, Fishing Derby, M Network Football, M Network Baseball, Decathlon. Not so strong on adventure games, although Adventure is rumored to like have, you know, started the entire genre and everything.
There are at least a hundred VCS games worse then ET/Pac-Man. Regardless, there has been no game in the entire history of video gaming that fell as far short of expectations as Atari Pac-Man. I don't even know what other game would come into the conversation.
ET was disappointing too, but to be honest there was no particular reason to expect a good game to come out of that... it's just that at the time the whole world was high on ET. Don't get me wrong, I think it's a terrible game, just not any more deserving of notoriety than, say, the Swordquest series.
