Surround / Chase

There's a multitude of ideas going on here, the Atari artwork shows two people playing Surround as a computer simulation (kind of how I've always envisioned it), while the Sears artwork depicts knights jousting, wagons circling, and what looks like people charging a wall.  I'm not exactly sure how the knights fit in, I can see the wagons circling, and as for the people charging the wall it's anybody's guess.  Still, I love the Sears artwork (probably because of the knights I don't understand).
