I love the concept art, especially the Rattler (Tank Smasher: how cool is that name? You don't have to guess its intended purpose) and the HISS. I like the idea of side by side seats that drop from the bottom.
The boxes of Joe toys that go on for miles and miles is a whole bunch of awesome; I had immediate flashbacks. Ah, the glory days. If only I had the money I have now back then.
