Those are cool...
But...
A local EM collector has one thats ten times cooler and better, and its called Lunar Lander, but there is basically zero info about it on the net!

Its made by Coin Tronics or some other really oddball company, but the art, gameplay, sounds and LM blow this set of 4 away!
I asked if I could go over to his house with a video camera so the world could see how alot of the really rare EM's work and he didn't have a problem. He's got 40 or so that I'd like to chronical since the information is scarce.
