I just wanted to note that I love the artwork for defender on the Atari cart. Tasteful inclusion of a svelte lady to add drama is duly noted.
I found the labels on many of the atari carts cool. Defender, Night Driver, Sword Quest, asteroids, Super Breakout, and even Pac-man just to name a few. The artists were definitely not afraid to get creative and most of the time they got their point across. I remember my parents buying the games because the covers looked fun.
