Disclaimer: First off, forgive me if this has been brought up and discussed before. It's been thirty years (damn!) since the Atari 2600 got it's home port of Pac Man, and a lot of discussion can be done in three decades. If this observation is a revelation only to me and I'm a few years late to the party, then nevermind.
Ever since I was a kid, I've loved Atari box art. I'd spend hours pouring over the images in the catalogs that came with the games, but it wasn't until earlier today that I really took a serious look at the Pac Man art and was surprised at what was right in front of me.
Atari's art almost always had this way of blowing your mind with their interpretation of the action taking place on your television screen. Remember the art for Outlaw? With it's visions of the Old West, of Conestoga wagons, and shoot-outs? The graphics? Not so much. Pac Man is the only game I can recall that uses the actual game play as the template for the box art. The "non-arcade" maze folks complained about? Right there on the box. The white(ish) ghosts? Right there. And Pac man? The way he's positioned in the maze, you'd naturally assume he's going to the right; Pac Man faces the direction in which he's eating, after all, right? The 'dots' below him have been eaten, and given the final product with Pac Man's inability to face up or down, it could be argued he may very well be going upwards. The Video Wafer? Yep. That's there, too.
The gist of my verbose rant? It seems like Atari knew in advance they were going to be selling an ersatz bill of goods. Even with other games released around the same time where the box art is a more literal depiction of the game play, Demons to Diamonds for instance, the art is a lot more exciting and stylized. Chrome skulls? Snazzy!
I now return you to you regularly scheduled discussions.
P.S.: I was there on release day for my copy of Pac Man, and I'm not a hater of the game by any stretch. Heck, being able to play Pac Man at home in the 80's was like being able to brag to your friends you had been to second base (wink, wink). Atari 2600 Pac Man wasn't the prettiest girl at the dance, but it was available and fun for what it was.
