Pitfall. Oh, gawd I loved this game. I was in love with the wild adventure of Indiana Jones (there was only one at the time), and as far as video games go, Pitfall Harry was the shizzle. The game's main flaw was that it put a 20-minute timer on the gameplay. You had to get as much gold and booty as you could in 20 minutes. Unfortunately, there was no clear objective, so you were left with your greed as motivation. Watch for a young Jack Black right at the beginning.
This is a commercial for Atari in general. They'd already released a crappy port of Pac-Man, which was programmed in a mere six weeks by Todd Frye. I loved it, but mostly because popular culture told me I should. Soon home video games would hit a lull which would be known as the dreaded North American video game crash of 1983. It was a dark time for home video games until a brave plumber named Mario came to save the day.
