Walking vehicles have intrigued me ever since I got my hands on the 6876-1 Alienator as a kid. Add to that my first contact with Star Wars was flipping through the channels and landing in the middle of the battle of Hoth with the AT-AT walkers. On the one hand, I get that walkers can be useful to travel over rough terrain, but they are soooooo sloooooooow, making them an easy target.
